Redesigned for thru hikers and long-distance backpackers, the Unbound 40 and 55 are lighter, stronger, and more comfortable thanks to an updated build with the exceptionally durable Dyneema® Woven Composite 3.9. Two contoured removable stays, a refined hip belt, and wider, more naturally curved shoulder straps improve support and comfort under heavier loads, while streamlined construction with internal seam taping and low-profile sewn-in daisy chains creates a cleaner, more functional design. A fully removable, customizable compression system makes it easier to secure trekking poles or oversized water bottles, while trail-proven features like the dual-entry front pocket, bottom pocket, V-Pull hip belt, and accessible side bottle pockets remain as intuitive and efficient as ever.

KEY FEATURES:
  • LIGHTER WEIGHT: With the new Dyneema® Woven Composite 3.9, the updated Unbound 40 and 55 offer better performance and comfort on trail while weighing less than the originals. 
  • MORE SUPPORT: Two contoured removable stays provide more support when carrying heavier loads, and redesigned wider shoulder straps feature a more natural curve for a better fit. 
  • STREAMLINED LOOK: A new modified construction allows seam taping inside of the pack without the need for the exterior binding, with a new, streamlined and user friendly sewn-in daisy chain.

Michael I. ★★★★★

Did 400 miles on the PCT this spring with the 55 and the load transfer is unreal — the hip belt keeps everything locked in even on steep sidehills, and the Dyneema weave shows zero scuffs so far. It's pricey but this is the first pack I've owned that feels just as solid on day 40 as day one.

William C. ★★★★★

The Dyneema woven fabric feels noticeably tougher than my old pack’s shell, yet the whole thing still rides light on my hips after a full 12-mile day. I’ve already scraped it against granite twice and there’s not a single mark. The 40L size swallows my gear without making me feel like a turtle.

Thomas ★★★★★

I was skeptical about upgrading my pack for the PCT, but the extra comfort from the redesigned build is real—my shoulders stopped aching by day three. It's noticeably lighter than my old pack, and the 55L carries a full bear canister without any sag. The Dyneema weave already shrugged off a few gran
