This is the battery-powered heated seat cushion that converts any cold, unforgiving bleacher or chair into a heated seat for up to 10 hours on a single charge. Powered by a rechargeable, long-lasting 7-volt lithium battery, the seat generates constant heat from a patented system of stainless steel fibers woven around thin heating panels and sealed in a waterproof coating. The touch of a button adjusts the amount of heat produced from 85º F to 135º F and the seat is lined with 3" of high-density foam that relieves point-of-contact pressure inherent in long periods of sitting at a ball game. An integrated shoulder strap ensures ease of portability to a sporting event or hunting stand. Battery lasts up to 10 hours on the lowest heat setting; two hours on the highest heat setting. Recharges via included AC adapter in three hours. 16" L x 14" W x 3" H. (2 3/4 lbs.)

To warm my bum during games.

Brilliant.

For when Mike starts playing Hockey again!
