I just purchased the best glove liners around.At least I hope they are the ones I think they are. I used to buy some from a Military store and loved them. They heat your hands up. They look like Michael Jackson gloves(white with sparkles) It is a metallic material built in to reflect heat back into your hands. I will post back when I get them. I used them when I worked in a Freezer -4. I put them on and a lite glove over them and was toasty.
