I just bought this Ronix at the boat show and its only an XL.
I'm 6'3 280lbs
My previous jackets I've always had to get xxl or even xxxl. What I really liked about this one was the fact it's not a mid drift. It was long & I really liked that. The XL on me is snug & I have to defiantly suck it in to get it zipped haha but I'm in the process of loosing weight so I'm not worried about it. It isn't CGA though.
