The Gerbing GT5 Hybrid 12V Heated Gloves Kit lets you stay warm and comfortable while you are cruising for hours. Simply connect these heated gloves for women and men directly to your motorcycle or snowmobiles 12V battery using the battery harness and long Y-harness (Purchased Separately). You can also power the heated motorcycle gloves by inserting the 12V Gerbing battery (optional) into the pocket on the gauntlet cuff when not riding. Stylish and functional, these nylon/leather gloves with tricot lining are made using Gerbings Microwire heating technology that uses micro-sized heating fibers to surround the front and back of the hand with warmth along with fingers and thumb. These electric heated gloves can be powered from your vehicles 12V electrical system, or from Gerbings 12-volt Hybrid lithium-ion battery pack (sold separately) with its built-in microprocessor temp controller. We highly recommend using these heat gloves with Gerbing Temperature Controller that allows the wearer to regulate the temperature to suit their requirements.
