55L Ultralight Backpack with Dyneema DCF in White, Medium | Unbound 55 by Hyperlite Mountain Gear

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.;.
