The Alpha SL Harness is built for mountaineering days when speed, weight, and efficiency matter most. It’s our lightest harness ever—yet still fully featured with two gear loops and adjustable, separating leg loops via the novel BraidLock™ buckle design. This harness also introduces WARP Strength Fusion Technology™, an industry first and a new construction that leverages laminated composites and braided ultra-high molecular weight polyethylene (UHMWPE) yarn to achieve exceptional strength with zero bulk—and keep you super comfortable while hanging.
