The Daehlie Challenge Jacket 3.0 Women's is your go-to training partner for conquering cold winter workouts on the trails. This technical cross-country skiing jacket combines a 3-layer softshell construction with targeted Fellex® ECO-FA insulation on the chest, delivering the perfect balance of warmth and breathability when you're pushing hard in frigid conditions. Strategic elastic panels under the arms and across the back move with your stride while providing crucial ventilation zones, while the ultrasonic quilting keeps the waterproof membrane intact for consistent 10,000mm protection against wind and moisture. Whether you're logging training miles on groomed tracks or exploring backcountry routes, this jacket's thoughtful design lets you focus on your performance instead of fighting the elements – because the best winter training sessions happen when you stay warm, dry, and unrestricted.
