Unbound 55 Pack

Features

Redesigned for thru hikers and long-distance backpackers, the Unbound 40 is 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.

• 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.
• Dual-entry stretch mesh front pockets ensure organized storage and quick access to gear.
• Large, easy-to-reach side pockets keep water bottles or gear accessible on the go.
• Exterior bottom pocket with dual entry provides quick access to snacks or trash storage.

Additional Features:

• Roll-top closure system with removable side compression straps for vertical compression.
• Updated removable hip belt provides more cushion and the ability to customize your pack fit. Built using Hardline with Dyneema, dual-density 1/8" closed cell rigid foam, 1/4" closed cell foam, and spacer mesh.
• Integrated plastic sheet with 1/4" high-density foam back panel.
  
• Seam tape on all vertical side seams and behind all sewn-on pack features.
