Osprey Kitsuma 7

A vertical-zip front compartment is big enough for a spare tube, multi-tool, and light windbreaker. Behind it, a separate external sleeve stores an included 2.5-liter reservoir with a magnetic sternum strap attachment for the bite valve. An AirScape backpanel features outstanding ventilation via airmesh-covered foam and a center air channel. A super light and airy harness with rolled, soft edges make for a pack so stable and comfortable you’ll barely notice it. Side mesh pockets store things you’ll want to access easily, like food or arm warmers.
