Keeps you locked in, beyond that: Meh.
This harness is... OK. The waist-belt was comfortable enough while belaying, but always rode up in a weird way when I was hanging on the rope.
The padded leg-loops always rubbed against each other and made me walk a little bit bow-legged to minimize that. I never needed to adjust the adjustable leg-loops, so that's just more junk to worry about.
I've also come to dislike the gear loops that flip up when not in use. It can make them hard to clip gear into if your shirt is any less than 100% tucked into the waist.
I'm updating this review after owning a Petzl Sama and giving it 5 stars of love. The Petzl is a superior harness in terms of comfort, lightweight, fit and function.
