Named by WIRED as Sports Gear of the Year in 2017, the Solar Charged Jacket is made from a highly responsive material that can be instantly charged and made to glow in the dark by any light source you can find. Whether you’re writing on it with your iPhone torch, drawing on it with a flashlight, charging it up underneath a lightbulb, or wearing it out in the sunshine, as soon as you take it somewhere dark it glows like kryptonite. And while this is the kind of tech that would normally only work in a lab, the Solar Charged Jacket performs amazingly out in the real world. With every detail laser cut and welded, it’s waterproof, stretchy, highly breathable, and so soft and lightweight you can roll it up into your hand.
