Men's Thermal Sock & Glove Liner Set in Metallic Silver

NASA-developed for deep space, these high-tech warmers will certainly keep you cozy here on earth! Made from special aluminized stretch fabric, they trap your own body heat to ensure a continuous flow of warmth not unlike holding your fingers and toes by the fireside. Wear them under your mittens and socks as an insulating first layer. Thin, comfortable and breathable, the gloves allow full dexterity; socks won't bulk up in your boots. Terrific for work or play!
