Familiarity: I've used it once or twice and have initial impressions
I am 5'9" and 153 lbs - generally athletic body with bigger quads/thighs and a 31" waist. The leg loops fit fairly tight over shell pants and long underwear (basically perfect). I could not fit much more under there but don't think I would if using the harness for it's intended use. The waist belt leaves just a bit of tail, not enough to tie off if you like to do that sort of thing - although the buckle design requires you to be doubled over anyway.
Shockingly light, seems well made, and literally the size of your fist when put in its bag. It actually seems like it might be comfortable too.
