When the Winter Games open in PyeongChang, South Korea, on February 9, many of the participating Olympic athletes will be wearing hi-tech clothing from the most innovative minds of their respective nations. These include aerodynamically-textured speed suits, training uniforms with biometric sensors, and most importantly, coats with programmable heat. Even color has been harnessed for what advantage that can give a team, whether it's for a psychological boost or to hide performance flaws. See seven of these clothing innovations in a slideshow at Smithsonian.
