Cooling for your butt
 

The Suzukaze (Cool Breeze) seat cushion is the latest personal air conditioning from Japan’s Kuchofuku, maker of air-conditioned beds and clothes. Using new materials and energy-saving fans, Suzukaze cools you in your seat without being power hungry or noisy.

To promote airflow, Suzukaze uses Super Spacer material that is soft and flexible, and transfers the softness of the seat you’re sitting on through the cushion to your body.

There's only one solution if you want your butt to be cool: don't wear leather pants.
