I measured right between a size L and XL. I ordered an XL, and it was a bit too big. I returned them for a size L, and they were a little tight. I stayed with the L, because I would rather have them stretch to fit my hands, than to have them be too big. I like to have as much finger dexterity as I can with my gloves.
I have put on a couple hundred miles with these gloves, and overall they are great gloves. My only complaint right now, is that with them being a little tight, and not fully stretched out, the seams on the inside of the glove can cause some hand fatigue. I am hoping that with a little more stretch, that will go away.
I have been riding in high 50's low 60's weather, and they have kept my hands comfortable. As the temp rises, I am hoping that the perforated leather will keep my hands cool enough. Time will tell.
Overall, they are a comfortable glove, and well constructed. I love the hook and loop wrist closure, the overall look of the glove, and the reinforced palm. I would recommend these gloves to a friend.
