Falke is introducing a collection of seamless underwear targeted at people who participate in winter sports. The German sports apparel brand says it is the first ever to have a plush-knitted inside. Called the First Layer Falke Skiing Comfort Fit range, the collection of 3D circular knitted underwear uses ThermaCool technology from Advansa to regulate moisture and temperature. Some fibers have a hollow core while others have channelled surfaces, which allows the fabric to protect the wearer from temperature changes, including a chill after exercising. The outside of the underwear has polyamide to provide an evaporative surface. At this point, Falke's new line comes in two long-sleeve shirts, a short-sleeve shirt for men, and three-quarter and full-length pants.
