Arc'teryx B360a Harness Reviews:

Positive Reviews:

I really like the B360.
I have a small frame, and find that the harness forms quite well to my body with a snug fit. The buckles are smooth and easy. When I hang in it, my weight seems to be distributed evenly and I don't feel any particular areas where the harness is digging into my body.
Still, the harness doesn't have a ton of padding--its not meant to--and I agree that it isn't necessarily the most comfortable harness to hang in for long, long periods of time--for example, if you are aiding a big wall--but on climbs like that, I essentially want a big-puffy chair of a harness.
Overall, I really like this harness. Its really light and is great for multi-pitch sport routes where you need to carry plenty of gear, or for those who climb big wall and prefer not to aid and want to save as much weight as possible.
Also, the harness looks really badass.

I like this harness.. A lot. I don't use it for big wall, I dont do much aid climbing, but I do love it for alpine, ice and trad. Its comfortable to me and LIGHT. Extra clothing probably helps. Plus the gear loops and ice clipper slots do add adjustability and options. I think if you are hanging out on a route carrying around a bosch, bolting, chill-axing, updating your status etc. then yeah its probably going to hurt. I havn't found a harness where that wouldn't be the case. But in this case light is right and I will go with it. Adieu.

Light weight, comfortable harness

Overall great harness, folds up and stores smaller than my BOD harness which is impressive. Can not even feal the thing once its on, but it takes a little longer than the BOD to put on and take off.

Negative Reviews:

I was disappointed with this harness. The padding beneath the waist strap kept flopping out from under the webbing and required a lot of readjusting. The lower loop you tie into while climbing would consistently catch sideways on a fall instead of dead center. I tried to remedy this by keeping the cinch on this lower loop as tight as possible but this either didn't work or came loose so quickly it didn't matter. Also that little thing was a bear to adjust. The big lumbar support was comfortable as were the large leg loops.

I have had 3 other of the older WARP harnesses from Arcteryx and have enjoyed them, but was hoping the rolling and pinching would be solved...but alas, it is worse! I tested mine out doing tons of hanging in it for cleaning new routes in Squamish, and all I can say is PAIN! Not comfy, the excess straps from the leg and waist belts don't stay in and dangle everywhere, I have not complained about a harness this much ever I don't think. BUMMER!
