They're a little big on me, I think, and they don't close into a fist real well. I'm tempted to take my pair apart, and use the mail to sew it onto a set of regular leather gauntlets (separating the mail into individual fingers, etc). It also probably wouldn't be hard to take the mail off, reduce the size of the leather, and put the mail back on. The same amount of mail in a smaller space would give it more stretch and compression to allow better flex.
The mail is sewn on in a very simple way. All they did was spiral-stitch a cord around the edges.
