Awesome. feather weight. I don't even notice it. Because of an elasticized triangle on the front of the leg loop, I can wear this in the summer sport climbing and over a down suit on 8000ers and still have the same great fit. Working routes can get a bit uncomfortable but that is the price to pay for excellence in nearly all other applications. Definitely in the category of "super gear". Be prepared to receive comments on the "flashy ness" of this harness.
