Psshaw, this picture is pure fiction. I went up there recently, and there's no ice at all.

All Day Comfort.

  • Familiarity: I've put it through the wringer

Ive used a lot of different harnesses over the years. This is by far the most comfortable harness I have ever worn, especially when you are in it all day. I am size 34 waist and the large is perfect. I can almost cinch it down all the way but, there is more than enough room when I am ice climbing in it. I just started trad climbing and this is the only helmet I have used for that so I cannot comment on the gear loops and such, ice climbing same thing, only harness I Have used to clip screws. Definitely use this all 4 seasons, I do believe the more trad or big wall specific harness they make is more breathable as this one as this use is specific to ice climbing, though I use it for everything.

All Day Comfort.

great harness

  • Familiarity: I've put it through the wringer

I love how thin this harness is. I was using it with a large backpack and any other harness I tried tended to be much more noticeable and rub uncomfortably.

I generally wear size 32 or 33 inch pants and the medium fits me well. It's just on the tight side but it's quite comfortable.

The only downside is that I've been having trouble with the plastic parts of the gear loops. A few of them have broken off. Not really a big deal though, the webbing part still functions fine as the loop.

Misses the Mark

  • Gender: Male
  • Familiarity: I've used it several times

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.

Doug - can you comment more on the size of the gear loops? How do they compare to the x350a? or just an actual measurement for size? I have the x350a and was considering upgrading to this harness based on it having more ice clipper slots and because the older one is gotten plenty of use and might be time to replace it; but am a little concerned based on your review (which is good, its what these reviews are for)

Responded on

Dave - Both of the gear loops are the same size as the smaller rear loops in the back of the x350a. Instead of having the large gear loops similar to the x350 and r340 (previous gen) in the front. They have moved to two smaller loops. So using this as a 365 harness, would be challenging, but not impossible. If you are looking for an update with more clipper slots and ample room for racking gear, I would recommend the B360a.

Responded on

I guess it depends on what we compare to. I bought this in Large as an upgrade/replacement for my old (bought 2005) Petzel Corax. I feel that the gear loops are noticeably larger on I340a than on the old Corax, which I consider a nice improvement. I have not yet used it for ice, so I cannot comment on clipper slots. I feel that only the far back will be good for screws. I feel that there is plenty of space for my rock rack, typical Gunks rack,which I admit may be relatively small. Actually, I do not need more space. If I were, I would probably carry too much gear, i.e., too much weight. Relatively, light weight is one of the reasons why I bought this harness, so having too much gear would kind of defy the very purpose. Just my 5 cents.

Responded on

I would agree with Doug. After using it couple times for ice climbing I can say that harness is very comfortable and lite but gear loops are not so great. The size is probably ok but location is quite inconvenient for me. I have three more harnesses and wanted this one for alpine/ice specifically as replacement for BD mountaineering harness (webbing basically). Will keep using it may be I am missing some "new technique"... Tried two sizes S and M but have decided to keep M. I am 5'6"" 153 lb.

I dig it...

  • Familiarity: I've used it once or twice and have initial impressions

Price is a little steep, but it's worth it. My previous harness was a 2008 model BD Momentum AL. Not a bad harness, but I didn't do enough homework before I purchased it. Doing primarily ice climbing, the Momentum doesn't have any ice clipper slots and fixing ice clippers to a gear loop doesn't work that well. After checking out Gear:30's review ( http://gearthirty.blogspot.com/2012/06/arcteryx-i-340a-harness-review.html ), I committed to the I-340a (Xenos was the other one I was eyeballing). I used it for the first time last weekend and most of the time I forgot I was even in a harness! It's super light and very comfortable. Self-locking buckles are a dream. Typical quality you'd expect from Arcteryx.

I am struggling with sizing this harness....

I am struggling with sizing this harness. My measurements fall right between M and L. Would it be better to take M and hope that I will still get in with some thicker closing or go for L and hope that I will be able to tighten it up in summer?

Responded on

I would go with a Large if it was me especially if you are going to get any Fall or Winter use out of it.

Responded on

I find these run a touch small, definitely go Large.

Responded on

I was in your situation recently- between M and L- and I ordered the M, thinking I'd just have to loosen the belt. Unfortunately, being on the very large end of the fit for the M harness was extremely uncomfortable! When I did try on a Large, the difference in terms of comfort was remarkable.

Best One-Quiver Harness on the market

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.

Responded on

Conor - do you have the x350a? I do, and it does have the drop-down leg loops, it also has ice clipper slots (3, to be exact). Just making sure that all the right facts are out there on these harnesses.

Responded on

I did have the x350a yes, however the "drop down" leg loops were a pain in you know what to operate with gloves on that model. On the i340a, the drop down function is vastly improved with the easy clip buckles. As well, being left-handed, the fact that the x350a has only 3 ice-clipper slots, was frustrating. I much prefer the fact that on the i340a, one can place their ice clippers wherever they see fit. Again, a big improvement over the x350a.

In summary, is the x350a a good harness? Absolutely (better than most on the market I'd say). That said, do I feel there have been improvements made with the new i340a? Yes.

Cheers!
