I got this as a gift, however I was able to try it on and use it for a few routes. The harness is so light and low profile that it moves with your body, and you legitimately FORGET that you're wearing it. This gets a bit weird up on the wall when you need to pat yourself down to make sure you didn't end up on a rogue accidental free solo.
Besides the stunning comfort, the gear loops are very nice and easy to hit or pull from in a hurry. I don't ice climb (yet, of course), but I like that it has the ice clipper slots as I can imagine this harness would be great up on some overgrown icicles. I did buy this as a gift, but after trying it out a little the notion of owning one is very tempting. If I do, I'll continue on this review after some heavy use.
One last note - the sizing surprised me. I'm a 32 waist and consistently wear medium pants/harnesses in everything I own. However, the small felt like it was made for my body. This may be because it's made partially for ice climbing and wearing over clothes, but in normal warm weather gear the small would be great for me. Probably best to get your normal size, but I thought it was worth mentioning.
