As an athlete with "skinny" wrists, and a size that falls in between brand "X" sm/md, these wristbands are great!!! Very comfortable and definitely absorb sweat.
My one and only complaint is the breath-ability of the material. For summer WODs, I can see them soaking up a lot of sweat, but than again isn't that the point of these?!
I completed a Murph with these under my grips and never once felt as though my hands were overly sweaty. I highly recommend these for those looking to add to their workout gear!
