If you've been to a game this winter you know how cold your ass gets sitting in those plastic stadium chairs for three hours. (You blizzard-braving Broncos fans know what I'm talking about.)

ColdHeat, the people who brought you the cold soldering gun, have developed a cordless heated seat that'll warm your ass for up to six hours on a single charge.

With three temp settings that'll hit 115 degrees Fahrenheit in less than 60 seconds, (insert rump roast joke here), the Heated Seat's long-life, rechargeable battery is good for up to 3,000 hours of use. Or about 1,000 football games. Not counting overtime.

To handle stadium abuse, it's made of tough, rip-stop fabric that's water resistant and easy to clean, (read: beer spills are no problem), and it has a body-conforming, high-quality foam pad to cushion your newly-warmed buns.
