JanSport's Katahdin 50L Backpack helps you track more miles than you might be accustomed to. Full padding at the shoulder straps, waist belt, and back panel give a cushy ride to keep you trekking, and the adjustable suspension system ensures a customized fit for even more comfort. The top-loading main compartment stores enough camping gear for three to five days. The Katahdin also features a sleeve for your own hydration reservoir, with a port and convenient clip on the shoulder strap. There's also a zippered compartment for your sleeping bag and a zippered pocket at the top lid for electronics and valuables. JanSport also equipped this backpack with a front stash pocket, a daisy chain to clip gear, dual water bottle pockets, and compression straps all around for a secure fit.
