Elaina T.wrote a review of Arc'teryx R280 Rock Climbing Harness - Women's on June 4, 2013
Familiarity: I've used it several times
I decided to buy a lighter weight harness for gym climbing and cragging. My SO has the r320a and he loves it, so I decided to try this version out. Before this harness I was using my Metolius safe tech deluxe, which I love for comfort and burliness. I still use my Metolius for outdoor adventures.
This harness is almost opposite of the Safe Tech deluxe. It's light weight, less adjustable, and it's not something I'd want to be wearing climbing off widths or chimneys. The thing is...it's so comfortable! You really do forget you're wearing it.. The leg loops and waist belt are made from a thin fabric, but they don't cut into my thighs or abdomen, even when hanging in the harness. This would be great for gym climbs, sport climbing, and even trad climbing, but I just don't it expect it to last long if its continually rubbing against granite.
I purchased the small. At first I was worried about it fitting too tight since I have wider hips and toned thighs. While I do have to wiggle to get the harness up my hips, the leg loops and waist belt fit nicely. I can't imagine getting a larger size as I'd be worried that the legs loops would be too loose. For reference I am 5'4, 115lbs.
