{"product_id":"hyperlite-mountain-gear-55l-unbound-s26","title":"Hyperlite Mountain Gear Unbound 55L Ultralight Backpack","description":"\u003cp\u003eThe Unbound is Hyperlite Mountain Gear's redesigned thru-hiking pack, built from Dyneema® Woven Composite 3.9 for an ultralight, highly abrasion-resistant carry. This 55L version scales up the design for longer resupply gaps and heavier loads, while keeping the same dual-entry stretch-mesh front pocket, twin side bottle pockets and bottom stash pocket for gear you need on the move. Removable, contoured aluminium stays and a V-Pull hip belt add structure and support, and 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 matters most.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDyneema® Woven
