The North Face Catalyst 75 Backpack - 4300-4900cu in

The incredible comfort and support of The North Face Catalyst 75 Backpack won it the 2005 Backpacker Magazine Editor's Choice Award. The secret to the Catalyst 75's comfort is the Pivotal suspension system. Pivotal gives you amazing support with its burly frame while flexing with your body to allow a natural stride and help your balance when you're on really rough trails. This 75L (4600cu in) pack from The North Face is a great size for backpacking trips up to a week. The Catalyst's sleeping bag compartment and side access lets you get to any part of the pack, so you can find your headlamp without unloading everything. There's even a removable hydration sleeve for short hikes away from camp.
