Unbound 40 by Hyperlite Mountain Gear

Ships in 1-2 business days | Based in Biddeford, ME | Est. 2010 Day in, day out: this is the pack for the longest trails Born from and for the most transformative journeys, the Unbound 40 is built to go above and beyond the rigors of thru-hiking. There is simply no better way to measure the effectiveness of a pack design than to send it out on thru-hikes. Over 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 will tell you the truth. So, that’s what Hyperlite Mountain Gear went after, and the Unbound 40 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 40 carry some of the weight.
