KNOW YOUR TECH breaks down the scientific technology used in your favorite sneakers and activewear. Let’s demystify your next purchase: today’s technology is Nike Sphere. This exclusive tech is used predominantly in Nike's running apparel and provides athletes with a warm, lightweight layer.

What is it? Nike Sphere is a high performance technical material with thermal properties. The idea of Nike Sphere is to trap air and warm the body without bulk and weight that can potentially slow athletes down. It creates a warm, regulated environment ideal for outdoor use during the fall and winter seasons.

How does it work? Nike Sphere works by minimizing contact points to allow the body-heated air to have free movement over the skin, which insulates but also allows for breathability. Its microfiber construction helps to pull sweat from the skin to the surface of the material for quick and efficient evaporation.

Notable products: Nike Men's Running Spring 2013 Line, Nike Sphere Bomber, Nike Premium Sphere Jacket 

Bottom line: Fall's officially here, and winter's just around the corner. Stay warm and comfortable during your outdoor treks with Nike Sphere technology.
