This was the first harness I've ever owned. I first owned the Medium size, but after a few months of use it had stretched to the point where it no longer fit snug (though this is partially because I was barely a medium). After sizing correctly, the harness fit just great. I've used it for sport, trad, and top roping at the gym, it is a very versatile harness. On multi-pitch climbs I've done in the past, it has become uncomfortable at hanging belays giving me "wall hips" that feel bruised for days. This could be due to my skinniness though. After about 2 years, it still works, just not the most comfy harness on multi-pitch days.
