The Assos 51.20.213.2O.S men's short-sleeved jersey combines breathability for road cycling with durability for mountain biking. The trailFit cut offers a more relaxed fit across the chest, accommodating protective gear and allowing freedom of movement while pedalling, while the longer body provides greater coverage on the bike.

The body is made from circular-knit Triangle fabric, with crosswise stretch and vertical stability. Despite its soft feel, it is abrasion-resistant and provides UPF 35 protection. Majestic fabric on the inside of the collar and at the sleeve hems wicks away moisture, while the sleeves feature a stable design for a better fit.
