We've seen our share of geek apparel that incorporates solar and battery power, iPod hookups and built-in cell phones, but nothing tops the ideas and innovations Ermenegildo Zegna incorporates into his pricey technology-infused clothing.
Zenga has improved upon his solar charged ZengaSport jacket, with his new "iJacket" coat made of "smart fabric." It uses Bluetooth technology that can be used for mobile phone conversations and has controls sewn into the sleeves and collar. This means you can talk to your friends (or therapist) through the coat's fabric without being a complete wacko. Although, there's no guarantee people on the street will think you're sane when they see you are taking to your clothes.
