Story
The ultimate 55-liter thru-hiking pack, built from ultralight, stronger-than-steel Dyneema®
Hyperlite Mountain Gear pioneered the use of Dyneema® fibers (an incredible material that’s lighter than Silnylon and stronger than Kevlar) over a decade ago to create ultralight, insanely durable packs for backcountry travelers. Trail-tested for tens of thousands of miles through rugged backcountry environments, the 55-liter Unbound Ultralight Dyneema Hiking Backpack is the ultimate thru-hiking companion, built to thrive in any terrain. Loaded with easy-access external pockets and daisy chains for near-infinite storage options, this thru-hiking pack is built to go the distance—again and again.

About HMG
Hyperlite Mountain Gear can’t be mistaken for anything else. It’s nearly weightless, packs down to almost nothing, and looks as sleek as NASA equipment. Based out of Maine, they use stronger-than-Kevlar Dyneema® fibers to design the most efficient gear possible—so you spend more energy covering ground, and less hauling your pack. We brought along their packs, totes, and camera pods overlanding and can attest that they’re pretty tough to beat. Now’s your chance to snag ‘em before our very limited supply heads out into the wild.
