Ardica Moshi Power System

Originally developed for military use, Moshi is the first apparel- heating system that’s strong enough both to warm clothing and charge portable electronic devices. Seven rechargeable lithium-ion batteries housed in a lightweight foam sleeve power heat-generating conductive yarn, warming the wearer of Moshi-equipped items like Mountain Hardware’s Refugium jacket ($230; mountainhardware.com) for up to nine hours between battery charges. At the same time, you can juice up your iPod or cellphone via a USB port (as many as eight times on a single charge of the battery pack) and even remove the slim pack to use as a portable gadget charger anywhere you go.
