In reply to John Kelly:
I have one and I f*cking love it. Super light, mine has 4 real gear loops, comfortable (almost as comfy as my regular rock harness), ice clipper slots. Can't recommend it highly enough for ice/alpine/winter use. It's not great as a summer harness because it's not as comfortable for hanging in, but it's still pretty decent. Weighs almost as much as a minimalist harness like the BD couloir but is actually serviceable as a harness.
The mesh outer layer is prone to getting "runs" in it, but it's just cosmetic. As far as sizing goes, I wear a medium in every harness I've tried, including the Air.
Go buy one.
