Purchased a pair for winter riding. I've been using them for some time now and the glove performed as expected. I consider myself having large hands, but I also find Castelli sizing chart one size too small. XXL fits me perfect. Keeping your extremities warm is a highly personal matter. I generally, do not get cold in my hands (although my toes are always cold despite winter shoes, wool socks or neoporine covers), so the gloves keep me reasonably warm in 28-30 F (plus NY wind chill factor). However, I also find Castelli products about 10F too warm compared to their product recommendation guide. All in all, great glove, for $35 can't go wrong.
