A pictoral representation of UIAA-105 and EN-12277 standards for harnesses.
Ultralight, and extremely packable, the Couloir is the harness of choice for mountaineers and skiers on steep snow climbs, short rappels and technical glacier travel.
For technical big mountain lines, crevassed ski terrain or moderate glacier climbs, the Black Diamond Couloir harness is a full-featured technical harness that packs down to the size of an orange and easily stashes in your pack or jacket pocket. Designed with a full-strength belay loop, the Couloir features low-profile comfort with a Speed buckle closure that makes for easy on and off while wearing skis or crampons. Two Ice Clipper slots 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 cordalettes, extra biners and other essential gear.
- Redesigned ultralight construction with hydrophobic fabric
- Speed buckle for easy on/off while wearing skis or crampons
- Full-strength belay loop
- Extremely light, packable and low profile
- Primary fabric is bluesign approved

If there are differences in weight (due to multiple sizes or optional accessories) we'll list them here.
The default weight is the middle-most size, often this is size M.

Number of Gear Loops
Gear loops are used to hold gear (quickdraws, cams, etc) onto your harness. 4 gear loops is most common.
0 - 1 Gear Loops
Most often on full body harnesses or guide/gym style harnesses.
2-3 Gear Loops
Mostly found on lighter harnesses made for [ski] mountaineering or high-end sport climbing where weight is a high priority.
4 - 5 Gear Loops
The standard/most common number for climbing harnesses. Perfect for sport and trad.
More Than 6 Gear Loops
Designed for long multi-pitch and big wall climbing, found on harnesses made to hold the maximum amount of gear.
Occasionally, the number of gear loops will change on a harness model depending on the size. There could be 7 gear loops for the med/large but only 5 gear loops for the xsmall/small. In this case we list the highest number for the filters, and then write an explanation on the product page like, “Size S/XS can only fit 5 gear loops.”

|Ice Clip Slots|
Ice Clip Slot
Ice clipper slots are made to fit a carabiner that holds ice screws. These slots are generally only used by ice climbers but there is no disadvantage to having them on your harness.
Less than 40% of harnesses will have ice clipper slots. And those harnesses will usually have 2 or 4 slots, often located next to, or between, the gear loops.
|Belay / Tie-In||One Loop|
|Waist Buckle Type||Quick Adjust|
|Leg Buckle Type||Clip|
Trad climbers often look for a haul loop as they're intended to haul a rope (second line) or pack (while you climb the chimney).
A haul loop can also hold shoes or other accessories. Although not the intended use, it is also commonly used to hold a chalk bag.

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
