Just picked up this jacket in a size small in black. I'm a 5'1, 125lb girl and I've heard that the women's freedom suit fits a little strange and that I should just size down in a mens, thats exactly what I did and I'm so glad.
I like my stuff a little baggy, so this fit is perfect for me. For anyone else that likes normal sizing and they are small like me, xs is your best bet. The quality is amazing, the fabric is not stiff at all, very soft and comfortable. I haven't been able to take it out yet but it seems like it's a little more burly than just a shell, I think just a good first layer and I'd be warm on the coldest days.
