The LifeStraw Go takes the hollow fiber filtration technology of the original LifeStraw and incorporates it into a sturdy water bottle. It’s a simple concept, but it’s executed well. The blue hard-sided water vessel reminds us of a Nalgene bottle, and it feels as though it could take some abuse. There’s a built-in carrying strap with a metal D-ring and carabiner, so you can easily attach this bottle to your existing loadout. The bottle top features a flip-up straw with rubber mouthpiece, and is attached to a replaceable filter cartridge that sits inside the bottle. This filter didn’t affect the taste of our tap water, and it did an excellent job removing particulates in our murky water test. We could see using the LifeStraw Go as a daily-carry water bottle, forgetting that the filter is even there at all. Considering the complexity of other filters we tested, we’d say that’s a big plus.


  • Affordable with low recurring filter cost
