With a robustness you can rely on in the terrain and 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 enhanced performance in a lightweight, 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.
