British adventure clothing brand Vollebak has launched a jacket it says is not just waterproof, it’s waterfall proof. The outer layer of the company’s Waterfallproof Puffer was inspired by the famously waterproof lotus leaf, which may look completely flat, but the surface is covered with microscopic bumps that cause water droplets to roll off it, rather than get absorbed. The second layer is a smart, waterproof and windproof membrane that can open and close in response to different weather conditions, changes in temperature, humidity and sweat. The third layer is an insulation made with silk-like, synthetic fibers that mimic the warmth and softness of down and are embedded with aerogel to increase warmth but without adding weight. This layer also has a water repellent finish. A good shake is all that’s needed to get the jacket dry. Photo: Vollebak.
