Say goodbye to frozen fingers with Swany's Wrist Warmers were designed with a soft nylon pocket that holds a hand warmer close to your wrist. Warming the blood at your wrist translates to increased blood flow to your hands and ultimately your fingers.  So your digits stay nice and toasty, no matter what the weather.  Made with a neoprene shell that has a hook and loop closure, the Wrist Warmer ST is compatible with Swany's own brand of hand warmers. Wonder Woman isn't the only one who has wristbands with special powers.
