This is my second pair of Oakley gloves and like the first pair the thumb is really tight and low volume (length is ok). They seem to be stretching a bit though so thats good. My hand is the much closer to a large in size than it is to an extra large but I purchased the extra large beacause my previous gloves from Oakley were Large and they fit tighter than I like. I wear large in almost all ski gloves etc... Anyhow, I would say these fit a little on the small side so don't be afraid to go up a size if you are in between. Otherwise the gloves are really sweet. I love the sweat cloth on the thumb for wiping when needed. The padding on the knuckles is just enough to make a difference if you clip a tree or something with your hand bars. They seem like they are built to last.
