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

    Surface Fabric is very durable
    Size: Small, Color: Hot Pink
    Surface Fabric is very durable, but the squeaker didn't last two months. I have urged the manufacturer to find a strong more durable squeaker for their product. My dogs really enoys it when the speaker works. One of his 3 work. I have just bought two more he likes them so much. He takes it to bed every night to catch it once or twice before sleeping. Also loves to catch it a few times during the day.

    Best. Toy. Ever. For My Superchewer!
    Size: Large, Color: Skinny Green, Size: Large, Color: Skinny Green
    Best toy ever! My dog destroys toys. Usually within about 15 minutes, she has de-squeakered and defluffed them. By the second day, she has tug-of-war-ed them to shreds. From the time we got this adorable dragon out of the package, she LOVED it. She set to work. It’s been a week, and while she has dewinged him, he lost his squeaker after a few days, and he looks a bit rough, he’s still in one piece! And, we’ve had HOURS of tug-of-war with minimal rips! She’s obsessed 😍 I ordered two more today. We’ve finally found the perfect toy for my baby!

    My 90 lb. Pitbull's All-Time Fave Toy
    Size: Large, Color: Coral, Size: Large, Color: Coral
    I ordered a plethora of new toys for Bruce to keep him occupied while I am working remotely from home. Poor guy gets so bored while I'm stuck in front of my computer 8+ hours a day. All the other toys are animated, but this one is just a big floppy chewy squeaky toy. Bruce quickly lost interest in all the other chirping, hopping, and twirling toys and fell in love with "Diny". When I opened Diny and gave it to Bruce, he had the elated and surprised look of a 3 yr old at Christmas. And he stayed that happy for hours, and then each time he picked up Diny to play. Diny became his go-to toy over all others (and there are many!). It is well made out of durable fabric, and they did not stuff it full of kapoc (I hate kapoc in dogs toys!). And it is delightfully low-tech. Normally he tears a squeaky toy apart as soon as he can isolate the squeaky mechanism. But cleverly, the squeaky box is loose in the long belly so it moves from one end to the other as the toy is handled. That made it difficult for Bruce to locate it. The toy remained in good condition for 2 weeks of near constant attention by Bruce. But yesterday he zeroed in on the squeaky box and ripped Diny to shreds. I was sad to see Diny go so soon. But boy-howdy was Bruce happy with it. I'm gonna buy another because we liked it so much. And so did I : )

    This is one “under the radar” gem!!
    Size: Large, Color: Coral
    This is one “under the radar” gem!! Very strong internal squeaker and way tougher than it looks. My big 125lb Shepard-Husky mix gave it heck, then made it his new buddy. He’ll occasionally give it the business but on the whole, it’s surprisingly tough and my big boy loves it. Nice price!!

    Cute but small
    Size: Large, Color: Skinny Green
    Cute stuffy and has not yet ripped. While my dogs plays with it, the toy is a bit small for him. For reference he is 120lbs.
