The Unbound is Hyperlite Mountain Gear's redesigned thru-hiking pack, built from Dyneema® Woven Composite 3.9 for an ultralight, highly abrasion-resistant carry. A dual-entry stretch-mesh front pocket, twin side bottle pockets and a bottom stash pocket keep gear accessible without opening the main roll-top compartment, while removable, contoured aluminium stays and a V-Pull hip belt add structure and support for heavier loads. Wider, naturally curved shoulder straps and adjustable roll-top compression straps round out the carry system. Suits thru hikes, multi-day trips and long-distance trails where low pack weight and genuine weather protection both matter.
