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.”

4 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.

Best winter Harness ever?

super light
Fully Featured
Quick to put on over crampons
leg loops can get tangled
I’ve used it a ton

I have used this harness as my Scottish winter climbing harness this season. When I first removed the chocus pro from the bag it comes with i was shocked at how light and thin it seemed. A bit too sexy really.  It really is super light and with no padding it packs down to a crazy small size.

It takes up next to no room in my bag and easily fits in side a helmet along with a belay plate.  

Despite its small size and weight it is fully featured and VERY comfortable.  As mentioned above it has zero padding as it has been designed specifaclly for alpine/winter climbing where it would be worn over winter layering systems.  I have found that the absence of padding has actually made it more comfortable than many of my other harnesses (such as my BD Zone). It doesnt seem to lift or rub in any spots at all, it feels snug and secure whilst tightened up bearing a full rack for scottish mixed.

The clipper slots are well placed and gearloops are generous, although they are made out of thin stiff cord they dont seem to catch on quickdraws they way you might expect.  The only critcism I would have is the second gear loop is a little far round your hips to your back, however the front loops being the size they are allows for all the important bits to be racked there (I usually rack 3 cams 5 draws and a set of offsets on one of my front loops for example) and for the other bits to be kept neatly out the way. The leg loop system works well but you need to get your head round spotting twists in the legs before securing them. I will admit to having started up an approach slope for my partner to tell me one of my legs were twisted upside down. This is probably down to it being so sexy and thin!

The belay loop is THIN, the tie in points seem to have been reinforced a bit more. I was bit dubious at first about the harness's durabilty, particularly using it for scottish winter, which often involves physical grovelling up chimneys and grooves, however i am pleased to report there are little to no signs of wear at all.

All of this considered its a FANTASTIC harness would recommed for mountain trad, scottish winter , ice and alpine. Get it and see for yourself its the best.

Outdoor Gear Lab Gear Review rating 5/5

This harness is divine for lightweight gear enthusiasts who are constantly trying to shave weight from their kit. It has all the features you need on any technical alpine route and nothing you don't. However, the major caveat is that this harness isn't comfortable for hanging. If you plan on doing long rappels or hanging from anchors for extended lengths of time, you'll wish you brought a more comfortable harness with more padding.

Climbing Gear Review no rating given just a review

The Choucas Pro, though a featherweight harness, is surprisingly supportive and has all the features you’ll need for a big day in the mountains. One huge selling point was the real gear loops—not like the dental floss found on other ultralight harnesses. The harness packs down to peanuts and is breathable while moving fast on route, and its light weight encouraged me to pack it for long days of scrambling in the alpine. While no single harness will become your go-to for trad, hard sport, and alpine speed missions, the Choucas Pro does each task quite well.

Choucas Pro Harness Review

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.
