Mountain Hardwear has integrated Ardica Moshi System into their Refugium and  Radiance Jackets

The Moshi System consists of a battery pack that powers both heaters incorporated in the jacket as well as a USB charging connector.  The system allows you to stay nice and cozy while on the ski lift while keeping your iPod fully charged.

Think2Build developed the circuit board and LED light-piping for the controller unit which is mounted to the front of the Jacket.  The light-pipe directs the light upwards for easier viability by the user.
