Dynafit has again used the Dryarn fiber in its spring/summer 2020 collection. Dryarn, a registered trademark of Aquafil, is a high-performance yarn specially developed for athletes who sweat a lot and may be exposed to frequent and sudden changes in temperature during their activities. A garment made with Dryarn is said to weigh 32 percent less than the same garment made from wool, and 34 percent less than the same garment made from polyester. According to the producer, the sweat produced during physical activity is transported to the outside, enabling a comfortable feeling even during the most intense workouts, and despite considerable temperature fluctuations. Salewa, Dainese and Macron are among the other brands who have been using Dryarn in their products.
