This winter, you can stay toasty and keep rocking with the iHat. Each toasty warm ski hat has a tiny FM transmitter that fits up in a pocket in the hat. A second transmitter attaches to your iPod. The transmitters beam music wirelessly from your iPod to headphone speakers in the ears of the hat. If you’re perfectly fine with wearing your hat over your earbuds or headphones, then forget we presented this.
