You've tried handwarmers on those bitter days skiing in Vermont and the powder days in Banff, but they don't last. The Seirus Men's Heat Touch Inferno Glove is your solution for all day heat in a serious way. There's 150g of Heat Lock insulation under the leather shell and palm, which provides enough heat during spring skiing, and the DryHand insert is waterproof and breathable to give you lots of water shedding protection. There's even a removable neofleece insert for added protection. But where the Glow sets itself apart is with the Heat Touch system. It utilizes flexible, durable soft heating panels for even, radiant warmth, and Li ion rechargeable batteries for up to six hours of heat. The soft toggle power button offers four heat settings, so you can dial it in to your ideal temp. If you forgot to charge the battery after yesterday's ride, you can hot swap batteries for continuous heating. You might even use these during those cold hand summer nights now.
