I thought it was one size fits all, they fit me perfectly. DH bought them for me on amazon - they had no sizes on that website.
The only problem I have is I sweat right after a warm up, and these gloves feel wet when I use them. I'm going to try to find out if they have some kind of under-glove type thing like a stocking for the hand that soaks up the sweat...I don't know if there is such a thing. Other than that, I just love them. They are so useful!!!!
