Choucas Pro Harness

For the same weight as comparable ultralight harnesses (like the bd couloir) you get gear loops with structure that are much easier to clip things to, 4 ice clipper slots, and leg loops with buckles that don't snap as soon as you go on rappel. Its not amazingly comfortable, but I was surprised at how little it bothered me when rappelling. The gear loops are sturdy enough that I have no concerns leading runout trad in the alpine, and I've started using it as my primary ice climbing harness. While the leg loop connecters are a bit tricky, a frequent climbing partner reported replacing the buckles on his bd couloir harness 3 times, something I'm happy to avoid.

I'm really happy with this thing. A good all rounder that can do most things! I also had a pretty tough time undoing the leg loops with my bare hands (as in I couldn't really do it) and I have concerns about the usefulness with gloves. Doesn't bother me much as I just sit down and walk the crampons through the leg loops.
Also the size chart is WAY off. I have a 32" waist at the smallest which puts me in the center of a size medium. I tightened the medium all the way down and still could slip a couple fingers in there. Need to return.

A fraction of the weight of my Arc Teryx and all of the comfort

Choucas Pro Harness

This has replaced my BD Couloir as my go to mountaineering harness. I have even worn it in the climbing gym a couple of times when I forgot my 'regular' rock climbing harness and it's surprisingly comfortable when lowering and belaying.
