My vote: None ( 3.3 avg )


Packable to the size of a soup can that easily stows away in a jacket pocket, the superlight Couloir harness is designed to be the essential skiing and mountaineering harness. Quick-release leg loops allow fast and easy changes while wearing skis or crampons, and low-profile webbing construction allows it to wear comfortably under packs or over clothing. Two webbing gear loops, four Ice Clipper slots and a belay and haul loop complete the package.

Gear Loops

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.

Worth Considering

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.”

2 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.

Haul Loop

Haul Loop

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.

Less than HALF the weight and space FTW!

uber lightweight
easy to adjust
works with alpine gear

This harness is absolutely ideal for what it is intended: Glacier Travel.

While not the absolute lightest harness on the market, it still does a mean job, coming in at a mere 230g. If wadded up carelessly, it is roughly the size of a coffee mug, and comes complete with belay and gear loops. This harness is much more comfortable than a traditional alpine bod harness, but still caters to the glacier-walker in all of us. Waist comes fully open and leg loops unbuckle allowing you to get this harness on over your crampons and all your puffy layers. Don't sacrifice pack space and weight by trying to use your sport harness for glacier--let the Culoir into your life, you will be well pleased.

A Mountain Journey Gear Review no rating given just a review

The Black Diamond Couloir harness is an essential piece of ski mountaineering gear. I haven’t seen many alpine harnesses that compare. I highly recommend picking one up. It comes in a nice burnt orange color (or black) so you’ll never lose it. It’s also a great stocking stuffer.

After that it's all gravy: two lie-flat gear loops, four ice clipper slots, offset buckle, haul and belay loops, and a reasonable price. All check. Oh, and one more thing: it only weighs freaking eight ounces! There are lighter harnesses out there - we've used most of them, and for race day or single day outings on vertical ice or rock we'll grab a specialty harness - but we only have eyes for the Couloir when it comes to expedition use. It really is that good. This holiday season do the mountaineer in your life a favor. If they don't have a Couloir in their closet, hook them up.

Rock and Ice Gear Review rating 5/5

Alpine harnesses are the ninjas of the alpine world. They are ultra-light and compact and can remain hidden in the tiniest corner of a pack until the assault begins. Black Diamond's new Couloir Harness exemplifies what you want and need in an alpine harness. It weighs just 8 ounces and is as spare as a Zen garden. The snap-on, snap-off quick-release plastic fasteners on the leg loops make donning the harness simple even when you are wearing gloves and crampons. The legs adjust to fit anyone from a ballerina to a sumo wrestler. Like most alpine harnesses, the Couloir waist belt has scant padding and the leg straps are basic webbing, keeping the weight down and relying on winter clothing for cushion, if in fact it is ever needed. Two gear loops keep mountain necessities like screws and flukes at hand.
Ironically, the Couloir's closest competition might well be Black Diamond's own and highly popular Alpine Bod. I've worn both, and while fond of the Bod, now prefer the Couloir, which weighs 7 ounces less, is just as easy to get off and on, and has a very handy belay loop.

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.
