I'm between Arc' R320 and the BD Chaos. I mostly climb sport with some trad. How do these compare?

To clarify on Jesse Lind's answer: the Arc'teryx harness' (harni?) are all made in Vancouver,BC, Canada. Arc'teryx product made in China, is made in an Arc'teryx exclusive factory. Keep in mind that most BD product (and about half of Arc'teryx) is made in China and still maintains the same high quality. It depends on the factory, not the country. There's plenty of junk made in this country, as well as good stuff.

Yep, I can try these on locally. Thanks for the input.

You're fine either way. Both are sport harnesses. Both are top-grade companies. It will just come down to personal opinion. Your physiology is going to be the determining factor. Can you try these on in any local gear shops? Just be advised that Arc'teryx has now moved most (if not all) of their production to China. Yes, you now pay the same outrageous Arc'teryx cost for the same Chinese made product. Ridiculous. As far as I know, BD still makes their stuff in the US, though I'd double check that if I were you.

I haven't climbed in the BD, but spent a couple years in an R320. The way I understand the difference is that BD adds a touch of foam, but the support system offered by the belt construction in the Arc harness supports weight more evenly.
