JanSport Klamath 55R
Here's what other sites are saying:
Since large doses of wilderness are all that keep you sane in our disconnected society, pack up the JanSport Klamath 55R Backpack and reconnect with the real, shrinking Earth. Happily exist in a natural ecosystem for a few days with a little help from the food, water, and layers you stow in this pack's 3300 cubic inches of pocket space. Even if you attach more gear to the exterior straps and loops, the adjustable GridFit harness and PE framesheet channel the weight to your legs for comfortable trekking many miles into roadless terrain.
Slightly smaller and lighter than the 55, the 55R's adjustable torso and dedicated sleeping bag pocket let you load up for multiday adventures and explore the wilderness in personalized comfort.
