The 20-liter R20 slots in toward the bottom of Kriega’s extensive lineup and is about the size of a typical student’s backpack. It has enough capacity to carry all the essentials for an overnight trip, but internal organization is limited to two zippered pockets. Oddly, the more you fill the pack, the better it feels. The R20 has a semi-rigid panel in the back that helps it rest flat on yours, and four cinch-straps compress the load and keep the contents secure and stable. Fully loaded, the pack hugs your torso like a baby lemur. It worked wonderfully for a variety of adventures, including aggressive trail riding where freedom of movement was crucial.
