Made for ice climbing, the I340a Harness from Arc'teryx is specially designed to make your trip up the ice as pleasant as possible. Strong Double-weave, four-way stretch fabric and warp strength technology swami all work together to make for an incredible durable, strong, and comfortable harness. Adjustable leg loops make for a precise fit, 14 ice clipper slots keep things organized and handy, and the reinforced tie-in points and gear loops make for a worry-free climb. There's a lot to love about the I340a Harness, except for the weight. It doesn't have much of that.
Arc'teryx designed the I340a Harness with ice projects in mind. Burly Double-Weave, four-way stretch fabric helps keep you comfortable while you battle with vertical mileage, and Arc'teryx's proprietary Warp Strength Technology swami helps spread pressure without adding weight.

The Arc'teryx I-340a Harness 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 anatomic conical shape for greater comfort while hanging. Fourteen slots present more options for clipping ice screws.

Arc'teryx I340a Harness Reviews:

Positive Reviews:

I've tried other harnesses out there, but in the end I keep coming back to Arc'teryx. In my opinion there is no better combination of lightweight, comfort and functionality than the new I340a harness.
Arc'teryx has fixed the lack of drop-down leg loops and added ice clipper slots that were lacking on the X350a harness, and have actually managed to shed some weight too.
The WARP technology keeps this harness so light and packable, yet surprisingly comfortable while hanging or belaying.
While a bit pricey, in my opinion, for Year Round climbers, there is no better one-quiver harness out there on the market.

Neutral Reviews:

Overall, I have found the WARP Technology harnesses to be amazing. They are both comfortable and light, perfect for the alpine. The i340a is no different. The revisions and improvements to the waist and leg loops in this generation are noticeable, or not noticeable as I barely can tell I am wearing it.
However, I do have some issues with this harness. The gear loops are very small. I realize that this is an ice climbing harness, but at $168.95, I planned on using this as my only harness. In order to fit a "standard" rock rack, I have to creatively rack the gear on my harness, which is less than ideal. The other main issue is, while clipper slots are plentiful, they are in not ideal locations and the elastic slots are only sturdy in the front (useless for screws) and rear positions (almost too far back). Using any of the slots will mean overlapping gear loops, which are already too small and thus losing more racking real estate.
I give this harness five stars for fit, comfort and compactness in the pack. Two stars for practicality and usage for tiny gear loops and ineffective ice clipper slots.
