Size chart of Arc'teryx Harnesses. Men, women and unisex.
The I340a is officially retired.You've found a page of history! The I340a is no longer produced by Arc'teryx and it is not available to buy from major online retailers. You can still check out all the specs and claim your ownership.
The I·340a is an ice specialist with the ultimate combination of lightness, suppleness and support. A wide Warp Strength® Technology swami gives greater support without adding weight. Brawny tie-in point adds more critical strength where needed and adjustable leg loops are patterned with an anatomical conical shape for greater comfort while hanging. Fourteen slots present more options for clipping ice screws.
Wear safety markers on belay loop and tie-in points.

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||Quick Adjust|
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.

Good, but not great. Given the huge price tag, I find it hard to recommend this harness unless light weight and packability are at the top of your priority list.
Arc’teryx isn’t known for making cheap stuff, and at $169 the I-340A is their most expensive harness. It is, in fact, the most expensive harness, period. I tied into the harness between 300 and 500 times, however, and the harness shows minimal wear. Although the I-340A feels flimsy, I’ll give it an “A” for durability, and I anticipate getting a couple more years of regular (two to three days a week) use out of it. Seems the old axiom holds true: You get what you pay for.
