Castelli Unlimited Endurance 3 Jersey Five pockets, no compromises, any terrain. When the ride stretches past four hours and the terrain keeps changing, fit and storage matter more than aerodynamics. The Unlimited Endurance 3 addresses that directly. Strada micro-mesh runs throughout the entire jersey, keeping airflow moving and moisture off your skin while stretching enough to stay with your body through climbs, descents, and everything in between. The fit sits slightly more relaxed compared to a standard road jersey, giving you the shoulder and arm freedom you want when the pace is honest rather than race-tempo. Load all five rear pockets with food, tools, and layers, and the elastic waistband keeps the jersey tracking true without riding up. This is the jersey you reach for when the goal is time on the bike, not time in a wind tunnel. Strada Micro-Mesh Construction - 92% polyester/8% elastane main fabric ventilates aggressively and stretches with you, managing moisture across long efforts in warm conditions Five Large Back Pockets - carries a full day's worth of nutrition, tools, and a shell without weighing down or shifting, thanks to a supportive elastic waistband that keeps the load stable Zippered Security Pocket - dedicated valuables pocket keeps your card and keys locked in place regardless of how much is going on in the other four pockets Full-Length YKK Vislon Zipper - smooth, snag-free zipper that opens and closes with one hand mid-ride, giving you precise temperature control without having to stop Raw-Cut Sleeve Endings - no gripper elastic, no binding at the arm, just a clean edge that stays out of the way on all-day rides | Castelli | Unlimited Endurance 3 Jersey Men's | Size Large | Polyester/elastane
