Zegna

NYTimes: Zegna Sport’s Solar jacket, the company’s next step in high-function design. Tricked out with solar cells mounted on the collar, the jacket converts sunlight into energy that will recharge the battery in a cellphone, hand-held device or iPod in four hours. For urban outdoorsmen who don’t have much time to bask in the sun, the panels and battery element are detachable, so they can bask independently. In black or silver microfiber and neoprene, in bomber, $995, or three-quarter length, $1,095, at Ermenegildo Zegna Boutiques, (888) 880-3462.
