The HT-7 Heat Tech Drystar® Heated Gloves feature Alpinestars Heat Tech System which distributes perfectly balanced warmth in the coldest of conditions. The smart system automatically activates when the hand slides into the glove, allowing the rider to easily regulate the temperature of the gloves, since the HT-7s are Bluetooth enabled and can be managed directly via Alpinestars Heat Tech App. Easily select your Alpinestars’ HT Heat Tech garment and connect your device to customize the desired heating level, as well as monitoring the remaining battery life and status. The gloves feature a 7.4v lithium battery for reliable, long-lasting power to the Alpinestars Heat Tech System - with electronic controller for long life and security. A micro-USB Y-cable is included to connect both batteries simultaneously. The Alpinestars Heat Tech Drystar System features a superior stainless enameled copper-nickel heating yarn for proven durability, bend resistance and heat stability.
