When we're tackling tough trails, we want a jersey that can stand up to the rough and tumble ways of mountain biking, and that's why we're throwing on the Defend Short-Sleeve Jersey. It features strategically placed abrasion-resistant zones that protect us and our jersey from dirt, debris, snags, and drags on the trail. We like that this jersey utilizes fully recycled materials, plus the mountain bike-specific tailoring that's perfect for all-mountain riding.
