Love your stuff. It's expensive, but I'm ok with that.
I've been a wrestler and a weightlifter all my life. I'm 6ft 220lbs and most of it is in my chest, neck and arms.
When I wear pants, ...they are size large, and my top is extra large. Every brand I can think of fits using that approach, from BDU's to ASICS sweats. However an Arc'teryx "XL" top is just a large or even a medium with freakishly long arms. That doesn't work for me.
That's the only reason I don't have a closet full of your stuff.
