The Heated Hat
This is the plush microfleece hat that generates up to five hours of toasty, battery-powered heat in wide zones directly over the ears. Equally at home on the sled hill or on the 50-yard line, this beanie-style hat contains an integral rechargeable lithium battery that delivers heat at three different intensities from microfiber elements woven into the fabric, delivering from five hours (on low) to two hours (on high) of heat.
A simple temperature control under the brim can be operated even with bulky gloves, and color-coded LEDs indicate which temperature level the user has selected. Recharges in two hours from the included AC adapter.
