The Leatt Trail 4.0 Jersey combines laid-back aesthetics with ride-ready performance, all while prioritizing the planet. Crafted from plush, breathable Tencel Lyocell fabric, it stays cool on your skin and naturally manages moisture. The material is made using an eco-conscious closed-loop manufacturing process and comes from responsibly harvested cellulose, the same stuff found in paper, making it both biodegradable and recyclable when its riding days are done. Cut for a relaxed fit, the jersey features a split hem that moves with you, ventilated back panels, and short sleeves to keep air flowing when you're grinding up technical climbs. Reflective accents boost your visibility in dim conditions, and an integrated eyewear wipe removes smudges after dusty runs. Built with Bluesign certified materials throughout, the Trail 4.0 Jersey is ready for your everyday trail sessions and earth-friendly riding.
