Really bummed this didn't fit right. Just got my 526SV and it's a lot better as far as the way my body fits the vest.
Sucks when that happens. But not every piece is right for every person. I hate that I can't wear the 634 cut.
It's a challenging vest as well. That 18oz is unsanforised and stiff as a board. Can I ask, were you using it over leathers?
No, the only size left was XXL so I was going to wear it over flannel, but the arm holes were too small for that, and the area in the back of the neck was bunching up. And it buttoned up, but would unsnap whenever I sat down.
