People who suffer from cold hands should try the Crazy ThermaBAnd. This soft fleece cuff holds a disposable hot pad in a pocket against your wrist, helping prevent veings and arteries from constricting and restricting blood flow to your hands and fingers; better circulation means warmer hands. A set of two Crazy ThermaBands comes with two Crazy HotPads. About $7.
