Designed to keep you pleasantly warm and comfortable in cool conditions, the Club Ride Men's Mason Jersey envelopes your upper body in cozy warmth while you pummel through rock gardens and sling your bike down twisty singletrack. Its Dri sulate Wool Blend Knit is made of a midweight blend 210 gm2 of polyester and wool, delivering the benefits of thermal insulation and quick drying, moisture wicking performance. Additionally, this fabric is rated at UPF 40, blocking harsh UV radiation during sunny trail sessions. Engineered with Club Ride's Sport Fit, the Mason Jersey fits closer to the body with a performance orientated cut that's not overly restrictive, but not too loose or baggy either. RideLight reflective accents boost visibility during cloudy conditions and after dark rides. Moreover, two rear drop in pockets add versatility for carrying trail snacks, extra layers, and even your favorite media player, with an integrated port for seamless audio integration.
