Excellent product. I ride a motorbike so needed some inner liners for my gloves and these are really worth it. I've had others that are thin and no use what-so-ever but these are quite thick and keep the wind chill off my hands to the point where if I have my heated grips on low, I can't feel the warmth coming through two layers.Rode to our local café the other day in the 'beast from the east' wind chill and my hands were chilly as opposed to blocks of ice that they normally would be. Just bought some for the wife for her gloves as well and will be buying these again when they finally go.
