I got these gloves despite reading online about people complaining they fit small, and are uncomfortable. They do fit tight, but that's how they are supposed to be. My hand is not very big, and I had tried on my friend's larges, and they fit nice and loosely, also very comfortable.
I chose to get the medium, because each finger fit very snugly, with the tips being a little loose. They are tough to get off your hand, which is good cause you know they are staying on if you hit the pavement. I pull them off buy cupping over the knuckles so I don't stretch the fingers out.
After about 150 miles, they were broken in very nicely, and felt as if I was hardly wearing a glove. The pre-curved fingers make it super easy to hold the grips.
Only issue I have is there is a seam that goes on the inside of my thumb, and after hours of riding it begins to feel tender.
Top Quality Leather, awesome glove, excellent comfort, and Alpinestars high level of excellence as far as protection goes.
