Our most technical climbing pack, built for light and fast missions from Alaska to Patagonia and beyond, the Speed Ultra 35lt combines an ultralight design with maximum durability.
This balance of weight and strength is largely achieved through an integration of Challenge Sailcloth's UltraWeave™ 200d body fabric combined with their UltraTNT™ PSA seam tape. The Speed Ultra’s durability is also boosted by the bomber UltraWeave™ 400d body fabric on the pack’s reinforced bottom. The Speed Ultra is a top-loader and the pack is also fully strippable with a removable waistbelt, lid and frame-sheet, as well as side compression, crampon and ice-tool straps. Inspired by the technology used in our Solution Harness, we developed a new, low-profile shoulder strap system that is extremely comfortable while remaining low-profile. Ice tool PickPockets™ feature a custom metal dogbone ice tool attachment, boosting ice tool security, plus the snag-free crampon straps and a tuck-away rope strap secure gear to the outside. Industry leading Siberian SR buckles are glove-friendly and never freeze up, and a double skirt design that’s easy-to-access keeps out spindrift and light precip.
