Description

When the chill rolls in and your regular jersey won’t cut it, Fox's Defend Thermal Jersey steps up to keep you warm, dry, and protected. Built for cool-weather trail days, this lightly insulated mountain bike jersey features a stretch grid fabric that delivers channeled insulation for warmth without the bulk, while actively wicking away moisture to keep you comfortable as you ride.

Designed with durability and trail performance in mind, it sports DWR-coated nylon elbows and a drop tail hem for added abrasion resistance and protection from mud and debris. The relaxed fit leaves room for elbow guards and extra layers, making it a versatile go-to for shoulder season shredding.
