The Junior features deuter’s proven Airstripes back system for effective ventilation. The S-shaped shoulder straps with Soft-Edge finish make it comfortable to carry and the sternum strap keeps the pack securely in place, even when running hard. In addition to a spacious main compartment, it has a stretch stash pocket on the front and stretch side pockets for a whole host of items. The extra-tough, PFC-free recycled fabric (using 13 x 0.5-liter PET bottles for each pack) makes this Green Button-certified, bluesign® product a practical companion for all their explorations in the natural world.
