I haven't tried them, BUT... they look a lot like the ski gloves I bought two years back for less money. I've found that using glove liners really helps a great deal. I like the Man***** polypro ones. You used to be able to get them at REI. I don't know if they still have them. As a reference, I use the Pearl Izumi Gavia Gloves with these liners on rides with temperatures as low as 20 degrees with good success.
