The Alnasca is Mammut's lightest climbing harness tailored for sport. It combines Mammut's most innovative technologies; Split webbing reduces weight without inhibiting durability or pressure distribution, while Mammut's Frame technology laminates the split webbing to mesh for a breathable, flexible feel. The Alnasca also touts a single self-locking waist buckle with elastic leg loops for easy on-and-off. There are two stiff gear loops that hold plenty of quickdraws, and two flexible gear loops behind hold belay gear as well as a few more draws.
