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.

  • Internal Frame
  • Padded Removable hip belt
  • Roll-top closure system with removable side compression straps for customizable compression
  • Top Y-strap compression - Designed to secure gear

    Quality control
    Size: Large, Color: Black-4 Pack, Size: Large, Color: Black-4 Pack
    They did fit well but now the waist band is coming off on all of them. Quality control needs to look into this problem. I would have bought them again if they solve this problem.

    Great!
    Size: Medium, Color: Multicolored19-4 Pack
    I have ordered three packages of these over the years. They are solidly made and withstand washing and drying without the color fading and elastic band stretching. They are sized correctly and are super comfortable.

    Cute, colorful underpants
    Size: Medium, Color: A-multicolored-4 Pack
    Bought these for my fiance because his old (other brand) ones were getting very tired. The price was great and they are brightly colored, which I get a kick out of. These do not bunch up while he's sitting, moving around, or pulling up his pants, and are comfortable with pants with a snugger fit around the legs and pelvis. They are soft, breathable, and durable, and have withstood numerous washes without an inkling of fading, tearing, and wear. I had some difficulties with the shipping and the original order never arrived, but this was immediately resolved after one contact with customer service. They were very responsive and sent out a fresh batch minutes later, which arrived very quickly and without any issue. Overall, impressed with the quality of both the underpants and the customer service.

    KIND OF BAGGY
    Size: Large, Color: A-multicolored-4 Pack
    I guess I'm not built quite like the guy in the photo. I found these to be a little baggy. I buy briefs because I don't want baggy. They were, however, comfortable enough. I liked the wider waist band and the elastic was fine. I wouldn't buy them again though.
