General: In typical Arcteryx fashion, the belt is extremely well made and is very robust and versatile for its weight, but also correspondingly more expensive than a "run-of-the-mill" belt.
The climbing harness is packed in a small mesh bag, which makes a high-quality impression.
It is immediately noticeable that the harness in the mesh pocket is significantly smaller than I was used to with my "old" Edelrid. This is probably due to the lack of padding, but it is by no means lacking. Despite the rather thin material, the harness is very comfortable and you can even take longer breaks when projecting without getting pressure points.
Even as a belayer, longer breaks for the climber are no problem.

There is more than enough space for quickdraws and other material in the 4 large gear loops. The rubber cover of the gear loops can be removed, but this is not recommended as they are rather wobbly even with the cover (but still very stable). There is a fifth loop on the back of the strap for attaching tag lines or similar (also good for attaching the chalk bag).
The four loops for gear/ice screw carabiners are also very solid and the gear carabiners are quite easy to mount.
The belt material itself is only a few mm thick, but still feels very robust and can withstand friction against rock or the wall of the climbing hall.
The leg loops are "one size", but have a rubber insert that allows for thick Gore-Tex trousers as well as thin shorts.

I have used the harness for everything from indoor sport climbing to ice climbing and alpine climbing and have had no problems with it so far; the harness shows no signs of wear and has been a very good companion in all environments.
My harness is size L and is in the tightest position when climbing indoors (thin pants + T-shirt), when ice climbing with a jacket and insulation layer it is about 30%; I am male, 1.74m, 78kg, athletic

Pros:
+very light
+comfortable
+abrasion-resistant
+real all-round performer

Cons:
-Leg loops may be tight for very thick legs in combination with winter clothing
-Material loops "flutter" quite a lot (up and down), with an empty loop you have to clip the first piece of equipment a little more carefully
-more expensive than many other belts on the market

Great handling, feels as comfortable as pajamas compared to my older harnesses, even hanging/abseiling for longer periods is no problem. I can't yet give a review of longer ski tours with it, but so far I would buy it again at any time

The width of the hip belt is great, it sits very comfortably on the back. The leg loops are brilliant with elastic bands that sit loosely but still fit snugly on the leg. TOP
