509 R-Series Windproof Jersey

The 509 R-Series Windproof Jersey is designed for racers and performance-focused riders who need lightweight protection from cold wind without sacrificing mobility or breathability. Built for snocross, hillcross, grass drags, ice racing, snowbiking, hill climbing, and cross-country riding, this technical jersey combines a polyester knit face with a laminated windproof layer and comfortable tricot lining. Breathable polyester birdseye fabric on the back and underarm areas promotes airflow during high-output riding, while the ergonomic eight-panel construction delivers a race-ready fit. A droptail hem with silicone grip helps keep the jersey securely tucked in throughout aggressive riding. Designed to integrate seamlessly with 509 gear and R-Mor protection, the R-Series Windproof Jersey provides the ideal balance of comfort, performance, and weather resistance for competitive riders.
