The rolltop expands and contracts to accommodate whatever you need to carry and wraps the contents of the pack securely to eliminate bouncing.










Load the pack with the gear you intend to run with, and put it on. Let the weight of the bag settle onto its balance point on your back—neither too high, nor too low.

Tighten the side adjustment cords so that the shoulder straps are wide on your chest and very snug around your rib cage.

Attach the sternum straps. Snug the top strap, and then the bottom strap. Do not overtighten — most of tension should be on the shoulder straps, not the sternum straps.
