The Baseliner Glove Liner slides under a bulkier glove on the coldest days or works alone when the chill is milder. GoKnit fabric holds enough warmth to matter without adding bulk, so it never fights for space inside a glove. A slim cuff with a pull tab makes it quick to add or remove between activities. The liner disappears against the skin, doing its job without adding weight to a pack or a pocket. What Our Gearhead(R) Experts Are Saying:"I keep these on through the whole day because I can pull out my phone without stopping to strip a glove first. My thumb and index finger stay responsive on the screen even when my hands are cold everywhere else."
