Arcteryx Alpha SL Harness

The Arc'teryx Alpha SL Harness is the lightest climbing harness the brand has ever made, built for fast-and-light mountaineering and ski touring when every gram counts. Weighing just 77g, it still carries two semirigid gear loops, plus low-profile UHMWPE loops that hold up to two ice screws for crevasse rescue. Its WARP Strength Fusion Technology™ bonds ALUULA Durlyte™ and Aeris X™ materials, stronger than steel by weight, with braided UHMWPE yarn to create a slim, high-strength chassis with zero bulk. Load is spread across the waist belt and leg loops, so you stay comfortable when hanging or belaying. Fully separating, adjustable BraidLock™ leg loops allow you to step into the harness without removing boots or skis, while the adjustable, replaceable rear rise extends the harness's lifespan. Packing down small enough to disappear in your pack, this ultralight alpine harness is a standout choice for glacier travel, ski mountaineering and technical alpine objectives.
