This Stratos backpack by Osprey is the perfect pack for day hiking, hauling heavy gear to the next climb, long days in the mountains, or hiking hut to hut. With a top zippered pocket for incidentals, two zippered slash side pockets-the left pocket offering zippered access to the main top loading pocket, two water bottle pockets, an interior hydration pocket, and a front stuff pocket for jackets or extra layers. There are also two zippered pockets on the hip belt for snacks or tools, a sternum strap, load lifters, and a zippered access to the mesh ventilation back that allows a water bladder to be place here as well. Dual tool locks with bungees for ice axes, hiking poles, or tripod, and plenty of compression straps round out the features.
