Gossamer Gear Gorilla

The Gorilla is Gossamer Gear's 50-liter thru-hiking pack, weighing 955 g with a removable aluminum stay that gives it real load-carrying structure rather than relying purely on packing technique. Rated for roughly 13 kg, it sits at the upper end of what a frameless-adjacent ultralight design can comfortably handle, and the padded, removable hip belt with pockets and a chest strap help transfer weight off the shoulders. An ice axe loop and side loops for trekking poles round out the exterior attachment options. Access is via drawstring collar and top lid rather than a roll-top, with a removable lid pocket, one front mesh pocket, and two side compression pockets for quick-reach items. The body uses 70D Robic ripstop nylon with a tougher 100D fabric on the base, sensible given the pack is rated for extended trips of six nights or more. At 19.1 g per liter it's heavier than Gossamer Gear's frameless models, tracking with its higher load capacity — this is the pack for hikers carrying more food, fuel, or cold-weather layers over long stretches between resupply.
