Used it all of once a few weeks back to climb a short top rope at the smoke bluffs in Squamish to test it out. It's the wrong size for me it turns out so I bought the exact same model again but in the correct size.
On a personal note, I bought this harness for mainly mountaineering use, as well as rock climbing use for rappels and the odd bit of climbing. I've used this model, in my correct size, a few times and it's excellent. It's super light and comfortable. The last time I wore it I completely forgot I had it on until I got back to our car.
The reason the asking price is so low compared to buying it new ($165 + tax) is that someone I know that works at Arc'teryx got it for me. I'm selling it below the price I bought it for as it's used. I'm not really looking to haggle on the price as I believe it is fair.
I live in Squamish and would prefer collection as I'm rarely down in Vancouver. If you are passing through early some morning for an objective in, around or north of Squamish I don't mind getting up to show you the harness.
