Rose Hip Tea: A Nutritious Backwoods Beverage

Written by

When it’s chilly out, there are few things more rejuvenating than a steaming hot drink that warms your core. However, if you’re out hiking or backpacking in the woods, it’s not as easy as stopping by the local drive-thru coffee joint for a latte. Those of us who carry coffee or tea bags in our packs can cook up a drink over the campfire, but it’s wise to know how to improvise some beverages as well. Rose hip tea is a great example — it’s easy to make, tasty, and packed with healthy nutrients such as vitamin C, beta carotene, and lycopene.

Rose hips are simply the fruits of the rose plant, which form in spring or summer and typically turn red, soften, and ripen by the fall. They often remain on the plant through late fall or early winter. A handful can simply be steeped in boiling water for about 10 to 15 minutes until the desired tea color and flavor are achieved.

Most varieties of rose hips are filled with small seeds, so you’ll probably want to strain them before drinking. These fruits can also be preserved for future use by drying them in an oven (or over hot coals) and grinding them into a powder.

The 3-minute video above from The Outsider shows the basics of finding and harvesting wild rose hips, as well as how to make rose hip tea. For more information on another traditional winter beverage, check out our previous article on Boilo.

Inforce 9 Zero Weapon-Mounted Light

Written by

Last Friday, we flew out to Georgia to attend the Big Daddy Unlimited Epic Shoot event — you may have seen our on-site coverage on our Instagram page as well as RECOIL’s Facebook live videos. While visiting the Inforce booth at the range, one of the representatives pulled us aside and said he had something new to show us. He then presented the pre-production prototype of the company’s latest weapon-mounted light, currently referred to as the Inforce 9 Zero.

The BDU Epic Shoot is an annual invitation-only event for manufacturers and media.

We had the opportunity to snap a few quick photos of the new flashlight, and then inquired about its details. Each Inforce 9 Zero is made from machined aluminum, and includes a reversible picatinny rail mount with a built-in activation button. Both 45-degree and 90-degree-mount versions of the light will be available — the pictured example is the latter. The button offers momentary (half-press) and constant-on (click) activation modes.

As seen above, there’s also a sliding lockout switch that prevents inadvertent activation when the weapon is being transported or stored.

A rubber dust cover on the back of the light flips open to reveal a tape switch attachment point. This switch will attach via strong magnets, requiring roughly 10 pounds of pull strength to remove the cable from the socket. The onboard switch can still be used alongside the tape switch, offering redundancy in case one of these elements is damaged in the field.

The new Inforce 9 Zero light is powered by either a single 18650 lithium battery or two CR123 batteries. With the 18650, it will produce 1,300 lumens and run for approximately 1 hour 45 minutes. With the CR123s, output decreases slightly to 1,100 lumens.

Inforce tells us that the 9 Zero will retail for $220 with the 90-degree mount, or $240 with the 45-degree mount. The tape switch will be sold separately for about $50. Estimated ship date for the first batch is January 2020, which means that we should be able to get our hands on the final production version at SHOT Show that month.

We also hear that Inforce will soon be releasing two new all-metal pistol lights, a two-battery light and a single-battery compact light. Stay tuned for more info here on OFFGRIDweb, or check out Inforce-Mil.com for more on the company’s lighting products.

Review: Zenbivy Bed

Written by

Editor’s Note: The following article was written by Hannah D., a 15-year-old up-and-coming outdoor adventurer. She tested the original Zenbivy Bed on several recent camping and backpacking trips, and shared some helpful feedback based on her experiences. We’re always glad to see the next generation developing an interest in nature and learning survival skills firsthand.

The ZenBivy Bed system is lightweight, comfortable, and rugged… but it’s also really confusing. At least at first. I didn’t completely figure it out until after I’d used it the first time, even though I watched some videos and looked over the website beforehand. It kept me warm though, despite using it incorrectly, so it wasn’t as bad as it could have been.

It is possible I should have listened to my dad and uncle, who recommended I field test in the back yard overnight before relying on it.

About the Zenbivy Bed

Zenbivy first released its two-piece sleep system in late 2017. Since then, the company has also added a Light Bed variant to its product line — you may remember that item from the previous OFFGRIDweb article about its IndieGoGo campaign.

I recently received a sample of the original Zenbivy Bed, which the company calls “the most comfortable backcountry sleeping bag ever designed.”  That’s a bold claim, but the product caught my attention.

The whole system (with pillow) weighs less than three pounds and features left and right zippers to secure the quilt to the fitted sheet. You can use it sort of as a sleeping bag and mostly like a quilt, with a little bit of both and neither depending on how you arrange it. If you’re someone who kicks the blankets off during the night, you will probably like it, though if you have one leg stuck out into the snow that will kind of defeat the purpose of using it.

The Zenbivy fitted sheet attaches to a sleeping pad or mattress.

Described as a two-piece sleeping bag, the Zenbivy Bed is designed with a top quilt and fitted sheet. That quilt can be tucked in during cold weather, or left untucked on warmer nights. The fitted sheet can be secured to a 20- to 25-inch rectangular or tapered sleeping pad to prevent the bed from sliding out of place, and features a hood for your head and arms. The 20D nylon shell is coated in a water repellent finish and filled with 700 fill-power HyperDRY water-resistant 80/20 duck down.

In the Field

If you pick up the Zenbivy Bed, it doesn’t seem heavy enough to really protect you from the cold. However, it does so very well. I used it on Pigeon Roost Trail in Arkansas with my Venture Crew back in late March.

Temperatures dropped to the low-20°F (-6°C) range with some wind chill, but despite how insubstantial it seems, the Zenbivy does a great job keeping you warm. It features an EN Limit rating of 23°F and a EN Comfort rating of 34°F.

It probably helped that I was using a good Marmot tent, too, but it does stand up to cold temps on its own well. I used it later for a week at Scout National Youth Leadership Training (NYLT) event and it worked great, though most of the time during that trip I was just sleeping on top of it. I don’t have photos from that time because we don’t keep phones with us during NYLT.

I also used this bag in early October on a backpacking trip with my troop. We hiked part of the Buffalo River trail system in Arkansas. We did not hike very far, but I’m okay with that because I still don’t have much experience when it comes to backpacking. Regardless, I was grateful for the lightweight bag. This campout was part of the requirements for our Wilderness Survival merit badge. Normally we would not be able to bring a sleeping bag, but because of the weather we were allowed. It got down into the 30s, and we had to build our own shelter that night! This bag made my night so much better — I would have been miserable for sure if I hadn’t had it with me.

Here are some additional benefits and issues I noticed while using the Zenbivy Bed.

Pros:

  • The material shed water very well, both rain and dew.
  • It’s light, fluffy, and comfy, and you can really compress it for storage. In fact, you could get it compacted even more tightly with your own compression sack than the stuff bags it comes with, if you wanted to.
  • I love the Zenbivy pillow. For how light it is, it’s a great pillow!

Cons:

  • If you’re not used to hooking your sleeping bag to your sleeping pad, it may cause you a few minutes of confusion.
  • The construction isn’t straightforward at first. I worked with it for a little while before finally there was an ah-ha moment, and I realized how it was supposed to go.

The assembly issue might not be as bad for experienced (or younger) backpackers. My dad and uncle were having some trouble figuring it out, but they’ve been using old regular-style sleeping bags for a loooooong time in the military and for camping. They had also been trying out a new bourbon for a while the night we were messing with it. This might have had some impact on their ability to put it together and explained why their attempts to wrap up in it were kind of a trainwreck.

Final Thoughts

I would suggest someone “test fire” a bag like this before using it. It isn’t intuitive. You definitely need to play with it for a little bit or watch some videos before using it in the field. If I had read some of the other reviews of the system, I might have expected that.

I was advised to try to put it together and to sleep outside in it before the trip to get a sense of it — more to see if it would be warm enough than to “make it work.” But I didn’t do so. Lesson learned: I’ll figure out my own gear on my own ahead of time. If I do get help from my dad or uncle, I’ll do so earlier in the evening. Or on an evening when they haven’t just gotten a kind of booze they’ve never tried before.

I would have preferred a better color than mustard yellow with a cactus green stuff sack, but that really doesn’t impact how it performs, and there are other options now available. I have recommended it since then to some of my friends.

Video: Comparing Car Jump Starters

Written by

It’s always a terrible sinking feeling when you turn the key in your car or truck and hear the engine fail to turn over. By the time you’re in the driver’s seat, you’ve already got somewhere to be, and this scenario means those plans are suddenly on hold. That might cause you to be late to work, miss a flight, or be unable to leave your home in an emergency. In some cases, you’ll be able to grab a pair of jumper cables and give your battery a boost from another nearby vehicle, but that’s not always possible, and it’s certainly not the most self-reliant solution. This is why we’re big believers in adding portable jump starters to the emergency kits in your vehicles.

Jump starters, or jump boxes, are essentially portable battery packs that can deliver a sudden jolt of cranking amps to start a car that has a weak battery. Each comes with a jumper cable attachment that connects to the battery terminals, and many of them include additional features such as a flashlight and USB output ports for charging small electronics. They can be built around common lithium-ion power banks, traditional lead-acid batteries, or other forms of tech such as supercapacitors.

A 500-amp load tester was used to determine the output of each jump starter.

In the following 20-minute video from the Project Farm YouTube channel, the host bought eight different jump starters and evaluated each of them based on a variety of tests. These include bench testing on a meter, starting a pickup truck with a weak battery, turning over a diesel tractor engine, and performing in freezing conditions. As with his previous experiments, Project Farm clearly states that he wasn’t sponsored by any of these companies, and presents the results in an objective manner before sharing his conclusions.

This test serves as another example that big, heavy, and expensive doesn’t necessarily mean effective. Some of the least expensive jump starters in the test performed the best, while also fitting into a small package and including helpful extra features. However, that wasn’t always the case — a few of the cheaper units failed miserably. Overall, we agree with Project Farm’s conclusion that lithium-ion jump starters are a good way to go. I carry one of them in each of my own vehicles, and although they haven’t been a literal lifesaver, they’ve saved me from waiting for roadside assistance when my car’s battery died on a 116°F summer day.

SKD Tactical PIG FDT Cold Weather Gloves

Written by

When you’re outside in frigid weather, you might reach for a pair of thick gloves or mittens to stay warm and avoid frostbite. But there’s a major issue with this strategy: the thick insulation that keeps your fingers nice and toasty also robs you of the fine motor skills you need for a survival situation or self defense. In search of a middle ground between warmth and dexterity, SKD Tactical has released a new set of gloves known as the PIG Full Dexterity Tactical Cold Weather Gloves — that’s a mouthful, so we’ll just say PIG FDT Cold for short.

SKD says this new PIG FDT Cold variant is ideal for staving off numbness on a frosty day at the local range. They combine the tactile potential of previous PIG gloves with a fleece lining for wind-resistant insulation, as well as touch screen compatibility on all five digits. A press release states that “the burning hot jealousy from your friends” coveting your sweet new gloves will aid in keeping you warm — that’s taking it a little too far, but we’ll give them credit for the wordplay.

The PIG FDT Cold is constructed with a textured silicone-print palm and terry cloth nose wipe section on the thumb. It’s currently available in black or white, but Carbon Grey will be available in December, and Coyote Tan will be available down the line in March. Sizes range from Men’s S-2XL and Women’s XS-XL. MSRP is $58. For more info on these and other SKD Tactical gloves, go to SKDTac.com.

Video: DIY “Inferno” Survival Matches

Written by

Winter is a little more than a month away. For many of us, that means cold and wet weather. When you’re outdoors in these circumstances, a fire becomes especially important, but also especially difficult to start. Between snow on the ground, scarcity of naturally-available tinder materials, reduced fine motor skills, and other winter factors, it may be a challenge to get a healthy flame going. Even if you already carry a few tried-and-true fire-starters in your kit, it’s always worth considering more creative options for the times when plans A, B, and C don’t work out. A recent video from Far North Bushcraft and Survival shows one such method, which is referred to as inferno survival matches.

Lonnie takes an old-school approach to survival. Just look at that majestic beard.

These matches combine powerful ignition sources with long-burning fuel in a compact, tightly-rolled form. Better yet, you probably already have most (or all) of these items around the house or in the garage. If you don’t they can be purchased online for a few dollars, or picked up at local hardware stores and camping, fishing, or hunting gear shops.

As Lonnie demonstrates below, each of these inferno survival matches consists of two stormproof matches, two strike-anywhere matches, a cotton ball, a paper towel, a few coats of melted-down candle wax, a discarded bicycle innertube (a.k.a. ranger band), and some rubber bands.

Lonnie says this design burns for around 8 minutes without the rubber innertube, but can be extended by as much as 50% with its addition. You may want to consider the way you’ll be using the fire-starter, and decide accordingly. If your fire will be used for cooking or built in a fairly-enclosed space, that burning rubber may be unpleasant. Either way, that long-lasting flame should be more than enough to ignite damp wood in a snowy environment. Lonnie lives in Alaska and often films episodes during the winter, so he’s frequently used it in these conditions.

Looking Back: Missing Hiker’s Body Found in Eastern Sierras

Written by

Studying the stories of lost, injured, or missing wilderness adventurers can help us become better-prepared for survival scenarios we may face in the future. Many of these stories end on a positive note, with the individuals being rescued or making their way to safety, but there are also those that end in tragedy. These sad incidents can also offer insights that we shouldn’t overlook. Last week, the Inyo County Sheriff’s Office was notified that 40-year-old Alan Stringer, of Huntington Beach, CA, had gone missing after embarking on a hike near Bishop, CA. Three days later, his body was recovered by search and rescue personnel.

A photo of Alan Stringer via the family’s GoFundMe page.

According to a statement by ICSO, Stringer set out alone for a day-hike on Sunday, November 3rd, into Inyo National Forest in the Eastern Sierra Nevada mountains. Concerns were raised when he did not return as planned on Monday. He reportedly did not disclose his specific plans or potential routes to anyone, but did have an InReach GPS locator/satellite communicator — unfortunately, that was “never activated” according to the statement. Stringer was said to be an experienced hiker who had participated in mountaineering training courses in the past.

If you’ve been reading our previous articles or studying survival skills, you’ll know the first two lessons we’re going to talk about. Number one: always let someone (ideally several people) know about your plans before you head into the wilderness. This might include your planned departure and return times, your route with as many specifics as possible, and what you’re wearing — all information that can help rescuers find you quickly. Number two: even if you’re experienced in the outdoors, it’s always a good idea to bring a buddy on your adventures. That way, if something catastrophic happens to one of you, the other will hopefully be able to assist or call for help.

The third takeaway here is that even with steps taken to prepare, disasters can still happen. Stringer had cold-weather clothing, cramp-ons, and an ice ax for dealing with the frozen terrain. He took mountaineering courses to improve his skills. He carried a satellite communication device that could send an S.O.S. message with his exact location. Despite all these wise choices, things took a tragic turn — it’s not yet clear exactly what happened, but it’s possible that he became incapacitated and was unable to activate the device. His body was found on a glacier at the base of Mount Darwin.

Alan Stringer’s wife is 37 weeks pregnant with their first baby. A GoFundMe was started on her behalf, and has already raised more than $20,000 to help with funeral and baby expenses.

Forgotten Weapons & InRangeTV

Written by

It’s no secret that most of the big social media sites aren’t friendly toward the subject of guns. Many content creators who use these platforms have seen their content demonetized, mysteriously hidden from subscribers, or have even had their accounts deleted with no warning or explanation. Even creators who focus entirely on educating their followers on the safe handling or historical aspects of weapons have faced these restrictions. This is one of the factors that motivated our sister publication RECOIL to create its own gun-friendly streaming video platform: RECOILtv. The growth of that platform has continued with the recent addition of Forgotten Weapons and InRangeTV.

If you’re into guns and their history, Forgotten Weapons should need no introduction. Its founder, Ian McCollum, who the Internet has lovingly nicknamed Gun Jesus, has been producing fascinating videos for years — we’ve shared a few of them here on OFFGRIDweb. We’ve learned a lot about obscure guns we’d never heard of, as well as the origins and inner-workings of some that are too rare or costly for us to lay hands on. His other project, InRangeTV, also has some great content beyond the historical and weapon engineering realm.

Check the 3:35 mark in the video below for McCollum’s announcement of Forgotten Weapons and InRangeTV coming to RECOILtv, or head over to the Forgotten Weapons channel or InRangeTV channel now to start watching some videos.

Review: Kershaw Launch 8 Folding Knife

Written by

Stiletto is an Italian word derived from the Latin stilus (stylus), a pointed writing instrument used for engraving clay tablets. In the modern lexicon, a stiletto is a knife or dagger with a long, slender blade that tapers to a needle-like tip. The exact origins of this blade design are lost in history, but many experts believe it to be an offshoot of the rondel dagger, a weapon developed for penetrating chain mail and passing between the joints of heavy plate armor.

The stiletto was a favored weapon among Italian assassins during the medieval period, and was eventually outlawed, but it remained a popular weapon among criminals through the end of the 19th century. Its ability to penetrate heavy leather clothing while being easy to conceal made it a desirable and stealthy tool.

A Famous Legacy

Though Italian in origin, the impact of the stiletto reached across cultural divides. During the Second World War, famed British close-quarter combatives instructors William E. Fairbairn and Eric A. Sykes designed the Fairbairn-Sykes Fighting Knife:

The F-S Knife was designed based on the fighting concepts the duo developed while serving in the Shanghai Municipal Police. It employed a stiletto design with a double-edged blade that tapered to a needle point. This knife saw use by the British Royal Marines and SAS, and is the sole symbol found on the “Commando Dagger” badge worn by those who have completed the British All-Arms Commando Course (AACC).

American forces also found use for the stiletto. The U.S. Marine Raider Stiletto was patterned after the Fairbairn-Sykes Fighting Knife and was the first knife to be designed by a Marine Corps officer, Lt. Col. Clifford H. Shuey. Unfortunately, Shuey changed some of the material specifications from the F-S Fighting Knife to reduce costs and the demand for strategic materials, which led to durability problems with the Raider Stiletto.

The V-42 stiletto, also based on the F-S Fighting Knife, was issued to the First Special Service Force (a.k.a. Devil’s Brigade), a joint Canadian/American commando unit. To this day, the V-42 is depicted overlapping crossed arrows on the crest of the United States Special Forces. Even where the stiletto is no longer in use, the historical impact remains evident.

Kershaw’s Modern Stiletto

The Launch 8 was designed for Kershaw by Matt Diskin, a widely-known maker of high-end custom automatic knives. It was based on the classic Italian folding stiletto that many of us grew up admiring through pop culture. Movies like The Warriors and The Outsiders depicted the stiletto switchblade as a staple weapon among rebels, and many of our parents kept these often-outlawed treasures safely tucked away with the family heirlooms.

The classic auto stiletto usually had a bayonet-style blade with a single saber grind and false edge. The Launch 8 has a more symmetrical shape reminiscent of the Fairbairn-Sykes fighting knife, but with the classic false edge. It’s unknown whether or not the Launch 8 was inspired by the F-S Knife, but even the handle profile, right down to its coffin-shaped pommel, is instantly reminiscent of the F-S design.

The Launch 8 handle is constructed out of gray anodized 6061-T6 aluminum. The 3.5-inch blade is CPM 154 steel with a stonewashed finish. This stainless steel offers corrosion resistance properties combined with toughness and excellent edge retention capabilities. When opened, the knife measures at a workable 8.25 inches.

The pivot pin for this spring-loaded auto is hidden beneath a carbon fiber handle inlay, giving the knife a clean, classic look. The push-button release/lock is located on the carbon-fiber side just below the pivot pin. The Launch 8 has a snappy release that will cause the knife to “launch” right out of your hand if you’re not prepared with a good grip on the handle.

With a closed length of 4.75 inches and a weight of just 2.3 ounces (68 grams), the narrow Launch 8 is compact and hardly detectable in the pocket. Its steel pocket clip can be mounted on either side for a tip-up carry.

Hands On

After unboxing our review sample, we noticed it was missing the carbon fiber inlay. This was likely a pre-production oversight, but an oversight nonetheless. However, this gave us a good opportunity to see how Kershaw’s customer service handled the issue. We called them up and explained our dilemma, without offering any indication that we were anything but a regular customer. Within 48 hours, we had a new carbon-fiber handle insert in our hands and had it installed in less than a minute. Three days later, a second brand-new Launch 8 arrived in the mail, followed by an apologetic phone call from a Kershaw representative. We’ll put an A+ in the grade books for Kershaw’s customer service.

The reversible pocket clip may be one of the most robust clips we have ever come across. Using a left-side pocket-carry, this author found himself frequently catching the clip on the seatbelt when getting out of a vehicle. Having experienced this problem with other knives in the past, including other models from Kershaw, the number of bent pocket-clips this author has experienced would exceed the word-count limit for this article to list out. After at least a dozen seatbelt snags with the Launch 8, not once did the clip bend, loosen, or lose tension.

We used the Launch 8 as a daily task knife to see how well it would hold up. We opened packages, cut up cardboard boxes, dug out splinters, and pretty much everything in between. The blade is still as sharp as it was out of the box and has yet to see a stone.

The stiletto blade is designed for penetration first and foremost. The thin, needle-point blade is ideal for penetrating clothing and slipping between ribs and other bone structures, making it an excellent choice for self-defense. Heavy-duty cutting tasks can be a little more challenging because the blade geometry causes the cutting action to slow as it draws toward the point.

The Launch 8 rendition of the stiletto blade design has a little more belly than its predecessors, which helps with cutting, but it’s still limited. We found a push cut to be much more effective with the Launch 8 than a draw cut. This is because pushing essentially reverses the blade geometry and allows the belly dig in as the blade moves forward.

Closing Thoughts

The Launch 8 is a beautifully-designed auto with characteristics reminiscent of the old-world stiletto and the iconic military fighting knives of the past. Its quality craftsmanship and durable design are an attractive addition to any knife collection, and the lightweight materials and slim design make it a joy to carry. With a price tag of $160, it’s a hard knife to pass up if you’re a fan of this classic style.

Video: DIY Solar Water Desalinator

Written by

Whether you’re stuck on a lifeboat in the middle of the ocean or facing a Castaway-style desert island survival scenario, you’ll face the cruel irony of being surrounded by water that you can’t drink. This dilemma is one of the reasons surviving at sea is so difficult. With a little ingenuity, you can extract potable water from saltwater, but the improvised methods of doing this all come with substantial drawbacks. For example, a solar still can convert seawater or even urine into drinking water, but it’s extremely slow — you might only get a few drops per hour. For maximum efficiency, you’ll want a desalinator that strips salt and other dissolved solids from water.

The copper condenser coil is enclosed in a cylindrical shroud to direct airflow from the fan.

Off-the-shelf desalinators are available, and they can be a great way to efficiently produce clean drinking water from seawater. However, these devices are often large, costly, and/or require frequent maintenance. Creating a DIY unit based on the principle of distillation is a good alternative, and a fun project to undertake.

The computer fan is powered by a AA battery pack, which is charged by a removable solar panel.

In the video below, the YouTuber known as electronicsNmore shows off a desalinator he made from a metal water bottle, sterno can, some coiled copper tubing, and an insulated mug. Since distillation relies on quickly cooling hot steam, he also built a solar-powered fan enclosure that constantly pulls cool air over the copper coil.

As mentioned in the video, this design was inspired by a previous water desalinator built by another YouTuber, NightHawkInLight. You can watch that video below for an alternative approach — it’s definitely a simpler design that would be easier to build and maintain in the field. However, it requires frequently discarding and replenishing the liquid coolant for the copper coil, rather than using air and sunlight. It’s up to you whether you’d want to spend more time up front building the complex (and potentially fragile) solar water desalinator, or spend more time during a survival situation maintaining a water-cooled desalinator.
