ThermoLogic offers adjustable heated gloves for the avid outdoor enthusiast. ThermoLogic tri-laminated gloves are ideal for all degrees of cold weather. With these toasty gloves, you will never have chilled fingers again. The metal clad polymer fiber filaments extend to the edge of the fingers (and thumb) and down the back, ensuring warmth throughout the glove. The control button on the thumb back allows you to adjust the temperature setting from low at 85°F (4 hours), medium at 100°F (3 hours), to high at 115°F (2 hours).
