As another reviewer stated, this runs small. Go a size up to be able to move comfortably. I usually wear a M/L and in this case the L left me with exposed wrists and belly line - short and tight. The neck opening is also completely symmetric (front and back) which makes the fit slightly awkward. The pic makes it look like perhaps a lighter alternative to other gambesons on the market. While the construction may indeed be a tad lighter, it is heavier than it appears in the pictures. It appears to be well made, as far as the seems go and such. That's a good thing for it's assumed intended purpose of wearing under chain/plate in cool weather, not so much for wearing to the faire when it is 90+ degrees outside, lol.
