HotHeadStore.com is where you can order a HotHead brand heated hat. I saw this new heated hat product at the Whitetail Expo. It's an invention of 2 women who live a mile from my daughter. The HotHead brand hat has a lining made of Under Armour wicking material and you insert mini hand warmers into pockets built into the underside of the hat at the top. Of course, the head has a large heat loss when out in the cold so adding heat to the hat should make a huge difference in comfort. Take a look for yourself. Orange and camo in fleece or knit.
