Complete thermal balance in different climatic conditions. This jacket offers an enhanced fit with increased thermal insulation. Built with Windstopper medium light weight triple layer fabric, (220 gr/m2) the Beta jacket is engineered to keep you warm when the mercury goes as low as 5Â°C (40Â°F). It feels like youâ€™re wearing both a jersey and a jacket, while being incredibly breathable and light enough for comfort in temperatures up to 18Â°C (65Â°F). Includes protection from wind and rain thanks to the Windstopper membrane. Allows you to ride under the rain and stay totally dry at least for the first 90 minutes. Used by World Tour Team Trek-Segafredo for training and racing in rainy conditions.
