Blue Ice Choucas Pro Harness
The Choucas Pro has little in the way or padding or frills but is the stripped down version of the highest performing alpine harness. You will be wearing this harness in the mountains over layers that will provide the padding the harness lacks removing redundant weight. The leg loops have small aluminum tabs that thread through specially designed loops that allow easy on-off even with skis or crampons on and use Blue Ice’s signature separating leg-loops to give comfort. The Choucas Pro has four gear loops, two ice-clipper slots and UHMW PE reinforced dedicated tie-in points and belay loop. Weighing a mere 140-grams for the Medium size.
Ultralight, fully functional 3-buckle harness with buckles on the leg loops for for alpine style missions into high mountains or multi-pitch rock climbs. The Choucas Pro is the ideal harness for climbing technical alpine terrain.

This harness is exactly what I was looking for, fully-featured, light, comfortable. I have had it about a month now and have used it glacier ice climbing, rock cragging, and on mixed alpine routes. It performs very well, you barely know you're wearing it and when it comes to weighting it, it's surprisingly comfortable (especially when dressed for colder weather).
Highly recommend this harness.
For alpinism, this harness gets everything right. I use it for solo alpine climbing and ski mountaineering. It really doesn't have anything you don't need, but has a surprising number of features for such a light harness. For example, it lets me run ice clippers for tools and screws, the waist is supportive enough to carry a light rack, and the easy-open waist and leg straps mean I don't have remove my crampons or balance on one leg to get it on. It saves me time in the transitions, and I hardly notice its there.
