Ive been using these all Winter with a pair of hot glove liners and they're absolutely perfect. I've raced most of the Winter weekends so far and there's not a mark or damage on the pam grip. Also, the grip is all over the hand part of the glove - only the back is not covered - which means no annoying little patches of wear/holes on your little finger, across fingers etc. Even on their own they're very warm AND one single pair has lasted all winter thus far! Bargain and perfect for Winter sailing.
