The Defend Thermal jersey is ideal for cold mornings on the trails, when a normal jersey is not enough. The Defend Thermal long-sleeved jersey relies on lightweight insulation thanks to the stretch fabric with grooves that provides insulation throughout the garment. Lightweight, moisture-wicking and with DWR water-repellent nylon coating on the elbows, this longer back model offers excellent abrasion resistance. Developed to give you maximum performance, this jersey has a loose fit that is compatible with elbow pads, allowing you to wear it whenever you want more protection.
