SunLoops heater holders are a patent pending, nylon spandex band,
specially designed to hold any air activated heating element securely around the hand. The heater holder “pocket” holds the heater in position, allowing the heat to penetrate, and also giving the hand freedom to move or hold objects (e.g. a ski pole, handlebars, a phone…etc.,) so the heater does not interfere with normal activities. In addition to being worn directly on the hand, heater holders can be worn underneath gloves to stabilize the position of the heater or even on top of lighter gloves such as fashion gloves or gardening gloves.
