As with the Reward Natural Socks, our brown heather hand warmers are knit from our natural brown heather yarn; meaning the color you see is produced by a blend of 100% naturally colored fibers. ?There is no dye used, just 80% naturally white mohair and 20% naturally colored Black Sheep wool, creating a warm grey-brown color and silky feel. ?These indispensable half-gloves leave your fingers free to use your smart phone, your keys, or to write, while keeping your hands comfortable. If your wrists and palms are warm, your fingers will stay warm; and you can draw your fingers into these soft gloves between activities. These mohair hand warmers may benefit people with poor circulation, diabetes, or Reynaud?s syndrome; many report relief from symptoms while using them. The hand warmers are seamless, soft, lustrous, elegant, with a luxurious feel, and are comfortable to wear indoors as well.
