Nike’s Sweat-Powered Self-Venting Running Jacket

Tired of interrupting your run to constantly take off and put on your jacket to help regulate your body temperature? Nike’s new Run Division Aerogami Jacket uses a special moisture-reactive coating so that when you start to sweat, a series of vents automatically open to allow air to flow right through the jacket to cool you down. Once it dries, the vents close again to help keep you warm by trapping heat.
