The Flex can be whatever you want it to be. The adjustable suspension and waist belt secure around most torso and waist sizes for a totally customizable fit. Three storage compartments are just a reach away, and four compression straps can handle additional gear. This compact pack features 650 cubic inches of storage and three interior organizational compartments. Yet with a weight of just over 1.5 pounds, you may not even realize you're wearing it.
