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.”

7 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.

Big Gun Harness Review

Outdoor Gear Lab Gear Review rating 3.6/5

It is toward the lighter end of big wall harnesses we tested (but heavy compared to a standard climbing harness). The harness vents reasonably well considering how thick the padding is. The gear loops are easy to clip gear to with their rigid plastic. At first I was not a fan of two belay loops but now I am a convert. You just have more options for clipping stuff. Even though I don't love adjustable leg loops, at least these tuck away nicely if you have medium to skinny legs for your waist size. Best of all, the leg loops are easy to completely remove at night, something that fewer and fewer harnesses let you do. The drop seat feature for dropping the leg loops is very easy to use.

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.
