These fit very tight, almost like neoprene. Sizing is correct, its just the type of material used. Very hard to get on when your hands are sweaty. I think I like conventional gloves better as these seem light and fit tight.
I bought this glove as a cheap set for occasional riding. they lasted pretty well, but by the 5th ride or so they started becoming loose and not fitting properly. They were good for the price, but don't last very long.
