Black Diamond Couloir Harness (2020)

1 review   |  

The Black Diamond Couloir Harness is a full-featured, ultralight, technical harness that packs down to the size of an orange. 

Easily stash-able in your pack or jacket pocket, and designed with a full-strength belay loop, the Black Diamond Couloir Harness features low-profile comfort with a Speed buckle closure that makes for easy on and off while wearing skis or crampons. For technical big mountain lines, crevassed ski terrain or moderate glacier climbs, this should be your harness of choice. 

There are two Ice Clipper slots that pair with an integrated ice screw slot in each leg loop to reduce clanking during long approaches and flat glacier travel, and two webbing gear loops secure cordelettes, extra biners and other essential gear.


  • Redesigned ultralight construction with hydrophobic fabric
  • Speed buckle for easy on/off while wearing skis or crampons
  • Two webbing gear loops
  • Four Ice Clipper slots with ice screw slot in each leg loop to reduce clanking
  • Full-strength belay loop

    Black Diamond Couloir Harness

    I bought the above as I wanted a lightweight harness for BASE jumping as on some exits we need to gear up and then abseil down to an exit point on a ledge. It needs to be lightweight as we hike with all our gear to the X it point and because I didn't want anything bulky to have to put on over my parachute harness. On paper this fit the bill and I am delighted with it. Also great and hassle free service form Rock+Run. Thank you .
