Fine tuned for hiking, Black Diamond's Nitro 26 Backpack is ready for day long adventures in mountains, deserts, and canyons. With a 26 liter capacity, this backpack has enough room for a lot of food, layers, and more. Its ReActiv suspension system includes shoulder straps and a waist belt that move with you on the trail. This innovative system provides maximum efficiency, ensures a natural stride, balances load transfers, reduces knee stress, and eliminates sore spots and bruising. Made with Black Diamond's OpenAir technology, the Nitro's back panel, waist belt, and shoulder straps circulate airflow to keep you cool in warmer weather. The zippered panel opens wide for easy retrieval of gear. Black Diamond also equipped the Nitro with an external access hydration sleeve for your own reservoir, attachment loops for trekking poles or ice axes, and multiple pockets at the front, sides, and waist belt for electronics, valuables, layers, and snacks for the trail.
