What Our Gearhead(R) Experts Are Saying: "I've been racing in the R-Core X jersey and it's insanely light without sacrificing durability. The stretch makes it super comfortable on the bike, and it breathes way better than most downhill kits I've worn. It's perfect for days when speed and mobility are everything." When we're charging through technical lines or dialing in race day runs, the R-Core X DH Long-Sleeve Jersey gives us the comfort, performance, and durability we need to stay focused. Designed to elevate downhill and enduro riding, this jersey takes everything we love about the R-Core line and makes it lighter, stretchier, and even more breathable. Four-way stretch fabric allows full freedom of movement when we're shifting body position on the bike, while moisture-wicking tech keeps us cool and dry during high-output rides. Built with strategic paneling and weight-saving materials, it's engineered to keep us comfortable at speed, from bike park laps to podium chases.
