A light, full-featured harness for technical big mountain lines, crevassed ski terrain or moderate glacier climbs, the redesigned Black Diamond Couloir harness packs down to the size of an orange.


  • Redesigned Couloir harness features a breathable, low-profile vari-width Dynex monofilament webbing that's ultralight and durable
  • 1 speed buckle on the waist with easy-adjust wings and diaper-style leg loops allows for easy on and off while wearing skis or crampons
  • Patented full-strength Infinity Loop for belaying is durable, seamless and low-profile, and the design eliminates the dreaded belay-loop-shift when the belay loop seam catches
  • 4 Ice Clipper slots pair with an integrated ice screw slot in each leg loop to reduce clanking during long approaches and flat glacier travel
  • 2 webbing gear loops secure cordelettes, extra carabiners and other essential gear
  • Color-coded waist and leg loops (inside/outside) make putting on the harness easy and intuitive
  • Extremely light, packable and low-profile; small size easily stashes in your pack or jacket pocket
