Become UNBOUND to go bigger for longer! The UNBOUND 55 expands your capacity for more adventurous trips by adding extra volume to accommodate seasonal clothing and gear changes, or more food and water when resupply points are fewer or farther in-between. There is simply no better way to measure the effectiveness of a pack design than to send it out on thru hikes. Over the course of 2,000+ miles and an average of five to six months, day in, day out, loaded and unloaded, jostled and dragged, and exposed to the elements, one of these long walks is going to tell you the truth. So, that’s what we went after, and the Unbound 55 is the honest to goodness result. Every carefully considered feature fought for its right to remain, leaving only the essentials required for an efficient, comfortable, adaptable, and dependable travel companion. Thru hiking is hard enough. Let the Unbound 55 carry some of the weight.

Honestly, I bought this mainly for the extra 55-liter capacity, and it's been a game-changer for throwing in bulkier cold-weather layers without sacrificing my food stash. The extra volume for seasonal gear is exactly what I needed for longer, more adventurous routes.

Natalie M. ★★★★★

Packed for a week in the mountains and still had room to toss in extra layers and a few liters of water—that added volume is a real lifesaver when the forecast shifts. The extra space makes it feel like a completely different bag on longer trips.

Sofia ★★★★★

The extra 55 liters of room meant I could finally haul both my winter puffer and a bulky camp stove without strapping anything to the outside. The main compartment swallowed a week's worth of food and water with space to spare, and the extra volume really saved me when a cold front rolled in mid-tri
