We know that solar power is often used by geeks, but how many of them have actually experienced the touch of a world class designer? Zegna has taken this task to create the Zegna Sport Solar Jacket by collaborating with Interactive Wear from Germany. This unique jacket features power cells that have been fitted into the neoprene collar, where electricity stored is transferred to your preferred device (MP3 player, cellphone) via conducting textile cables. It takes approximately 8 hours of sunlight to charge up the entire li-ion battery. Word has it that the Zegna Sport Solar Jacket will be part of its 2008 summer collection – you can be sure it will cause a big hole in your pocket to pick one up.
