Sender Harness

Mammut's Sender series consists of high-performing climbing gear for all styles of ascent, and the Sender Harness is hyperlight and geared for all-around sending. It has that light, breathable, free-moving design that sport climbers love to fall into when they're projecting, and it's extremely packable for mountaineers and ice climbers. Mammut added four attachments for ice screws, and there are two rigid gear loops and two webbing gear loops for cams and quickdraws, and Mammut added a haul loop and chalk bag attachment for a full arsenal of climbing gear for whatever route you want to send.
