Born from and for the most transformative journeys, the Unbound 40 is built to go above and beyond the rigors of thru hiking. | WINNER OF: 2022 GEAR PATROL GP100 AWARDS “BEST IN OUTDOORS” | 40L PACK, IDEAL FOR Long Distance Backpacking & Thru Hiking Any Environment DAY IN, DAY OUT. THIS IS THE PACK FOR THE LONGEST TRAILS 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 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.
