Nike created Dri-FIT technology to help keep you warm throughout the day and during workouts. These modern cold weather clothing are ideal for wearing freely during the present tundra-like circumstances. They're also perfect for runners who want to stay warm while maintaining full movement of the limbs. Using science to improve human performance, Dri-FIT is a fabric treatment that allows heat to be transferred from your body into the garment's fibers so that it can keep you warmer longer. The technology works by using a combination of polyester and nylon fibers that allow moisture to be driven away from the skin to the outside environment, thus preventing any buildup within the garment. This fabric is used in a wide variety of products, including running clothes, baseball uniforms, and basketball jerseys. It's also been popular with skateboarders because the flexible material allows them to move more easily while staying warm. Nike uses a different term for their equivalent product: Air Motion Technology. This technology was first introduced into footwear in 1995 and has since been added to other items of athletic wear including gloves, hats, and coats. It should be noted that although these garments are designed to keep you warm, they may not be appropriate for use in high heat environments such as an oven or sauna.
