The REI Flash 22 Pack combines an ultralight design with comfortable touches for your day on the trail.

It features stretch-mesh on the shoulder harness and hydration system compatibility and the hip belt and sternum strap are incredibly comfortable to wear snug throughout the day, but if you're finding that they get in your way, you can bet that REI has your back - they're both detachable.

The organization design on the 22 Pack is also incredible, offering 3 exterior pockets, one top lid zipper pocket and even two daisy chains for hanging extra gear off the front.
