For a long day of adventure climbing any time of year, grab the Osprey Hornet 32 Backpack, an ultra-lightweight pack with plenty of room for all your gear. It has a 32 liter main compartment with plenty of room for extra winter clothes, along with three outer mesh pockets that are perfect for storing items you want to reach quickly, like energy bars or a rain jacket. The Osprey Hornet 32 also has a separate reservoir area that's super convenient, allowing easy access to hydration. The removable top lid has a mesh pocket, too, which is perfect for storing maps, compass and snacks when doing quick summit hikes in the summer. This lightweight pack is made of triple rip-stop nylon that wears superbly and feels so comfortable--almost as if you have nothing on your back at all. A removable back pad adds to the plush feel of the Hornet 32 Backpack, as do cushioned shoulder straps and a fully adjustable hip belt with another convenient zippered pocket.
