With a robustness you can rely on in the terrain and a lightweight insulation for the cool morning hours on the trail, the Defend Thermal Jersey allows you to tackle the toughest trails with confidence and warming comfort. The stretch-grid design provides targeted insulation with improved performance in a lightweight and moisture-wicking material that keeps you warm and dry. In terms of trail-specific features, the nylon elbows with DWR coating and the extended drop-tail hem at the back offer increased abrasion resistance, while the relaxed fit leaves room for elbow pads when you push your limits on rough terrain.
