The TRIAB 18 is designed as a one-strap sling bag that can be used for a wide range of applications. For those who like a traditional-style pack, a second strap is also included for two-shoulder carry configuration. It's rugged and accommodates a hydration bladder in a slot pocket at the rear. It has hydration tube routing provisions at the top of the bag as well as on the shoulder straps. A unique feature is that the TRIAB 18's large main compartment is accessed through the bottom, requiring the user to set the bag down to open it up completely. For those who like access to the entire interior of the bag this is a good thing since, when unzipped, it opens up completely. It has MOLLE on the front and sides and has plenty of hidden zippered compartments throughout.

Pros:
– Modularity up the yin-yang
– Hidden compartments galore
– Sling bag that can be converted into a two-strap backpack

Cons:
– Access to main compartment is only through the bottom
– No reservoir included (it's shown here for demonstration purposes)
