The perfect companion for day trips along airy ridgelines and through cool wooded trails or desert slot canyons, the Black Diamond Nitro 22 boasts a reACTIV suspension with high-flow OpenAir backpanel, shoulder straps and waistbelt to maximize comfort. Zippered panels provide easy access, while front, side and hipbelt stretch pockets house need-to-reach essentials, and an external-access hydration sleeve keeps your thirst at bay. We've also added stretch-mesh side pockets to keep essentials secure while you bound down the trail.
