I have an older R280 harness from 2010, got this thinking they'd be the same. Nope! Chuck Testa... I mean, it's not as comfy as the old one. The edges where material is welded together are rough and chafe. No big deal if I'm wearing pants and shirt but the sizing is a little off too - leg loops were tight while belt is huge.
The quality is not what I am used to with Arcteryx.
