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.

Disclaimer
I paid full retail for this, am NOT a sponsored climber, and only “curmudgeon” when companies quit making something amazing, eg. LaSportiva’s Gandalf approach shoe...

 

They don’t make harnesses this amazing anymore, it’s almost as if Deadbird thought:

“...if we stop making this, we’ll settle into a great little nichè of ‘gear-dweeb-history’!”

It’s actually quite perturbing, but alas I can see how such a specialized harness wouldn’t sell...

UK Climbing Gear Review no rating given just a review

Overall the M270 is a lovely but rather specialist bit of kit. Arcteryx's own description 'designed for performance-focused ice and mixed climbers' seems very fair; it won't be the difference between you getting up Tower Ridge or not, but for those pushing the harder grades, if it's racking system works for you, the M270's lithe strength makes it a very attractive choice. A winter-specific harness may seem a bit decadent to some, but then some of us spend a third or more of our climbing year in crampons, plus of course it will mean your summer harness will wear out less quickly!
