FrontRunners: Heat Couture
In addition to keeping you warm, the Zegna Sport Ecotech Solar Jacket (www.zegna.com) by Ermenegildo Zegna can recharge your cell phone or iPod. The lightweight garment ($1,500), which is made largely from recycled plastic bottles, features a detachable solar-powered heating-and-recharging system. The system is made of machine-washable textiles, with some components in and on the jacket’s sleeves. The solar panels connect to a rechargeable lithium battery in an inside pocket; the battery can heat up the jacket collar and, after about five hours of direct sunlight, charge your electronic devices.
