I've used this on rock and ice, and I've never had any problems with comfort. This harness is extremely light, and the minimalist construction doesn't seem to take away from my comfort level on sport climbs. However, I haven't tested this on any multi-pitch routes or big walls.  

Unless you really plan on adjusting the leg loops, go with the non-adjustable option

I'm 6'3" and 190 pounds, and the large fits me well.  

I wish the excess straps could be tucked in better on the main belt and on the adjustable leg loops.  The extra seems to dangle and doesn't stay tucked in. 

Also, nobody has a better warranty than Arc'teryx, and I'd rather pay a little extra for their service and product longevity.

Here's what other sites are saying:

The most comfortable fully adjustable all around rock climbing harness available. New, wider Warp Strength Technology (WST) swami belt and fully-adjustable conical leg loops provide supple comfort while hanging on the wall or belaying. A stronger tie-in point adds more strength to a critical area of the harness.


Wrap Strength Technology gives the Arc'teryx R320a Harness a level of comfort that far surpasses nearly any other harness while reducing weight to about half that of a similarly sized harness. This unique construction spreads your weight over the entire surface area of the harness to support and cushion your body without the need for heavy, bulky padding. Not only are the leg loops adjustable, but they're also completely removable so you can take them off and have a little more comfort if you end up at a bivy. All of the buckles are self-locking and quick-adjust so you can't forget to double back and can make quick tweaks to the fit whenever you'd like. Take all of this into consideration, and you're going to have a hard time finding a better harness for long, hard free routes.
