When the temperature drops but your training intensity doesn't, the Daehlie Challenge 3.0 Jacket delivers the perfect balance of warmth, weather protection, and breathability for active cross-country skiers and winter athletes. This quilted softshell jacket features a sophisticated 3-layer construction with PU membrane that keeps wind and moisture out while allowing sweat to escape during high-intensity training sessions. Strategic Fellex® ECO-FA insulation targets your core with ultrasonic quilting that won't compromise the membrane, while elastic panels under the arms and across the back ensure you can move freely through every stride and pole plant. The articulated raglan sleeves and regular fit work together to eliminate restriction, making this your go-to choice for cold weather workouts where staying dry, warm, and mobile makes all the difference between a great training day and cutting it short.
