Comfortable & Supportive
I love that this harness has so many additional safety features on it, like the dual belay loops and rated gear loops. It doesn't dig into your legs and cut off circulation, thanks to all of its adjustments. However, it does take a bit of time to get everything set just right to fit your body.
If you're in between size measurements, I suggest going down to the lower size. I originally bought a medium, but had to exchange it for the small so I had enough free webbing to tighten the waist.
I haven't taken it outside yet for any multi-pitch and hanging belays (two of the primary reasons I selected this harness), but my climbs/belays in the gym have been super comfortable.
Thanks Metolius for a harness that minimizes possible user errors and Backcountry for retailing it!
