Picked this up one year ago and never looked back. This thing is sick. By far the most comfortable harness I've ever worn in terms of all-day comfort, and then it folds up to half the size of other harnesses. Also, a smaller detail, but the gear loops feel much easier to clip than either BD or Petzl.
Leg loops might be a little tight for those with bigger thighs, but overall sizing actually felt large. I'm usually a medium, and I fit into a small cinched as tight as it can go.
