Leatt Jersey MTB Trail 4. 0 Long Sleeve Made from TENCEL Lyocell The Trail 4. 0 Long Sleeve Jersey blends laid-back style with technical performance and stands out for its sustainability. Made from soft, breathable TENCEL Lyocell, it feels cool against the skin, wicks naturally, and is produced through a closed-loop process that minimizes environmental impact. Derived from sustainably sourced cellulose (the same material as paper), TENCEL Lyocell is both biodegradable and recyclable. Long sleeves with abrasion-resistant panels offer added protection from overgrown trails or harsh sun, while perforated back panels keep airflow high on warm climbs. The regular fit and slitted hem move comfortably on the bike, and thoughtful features like reflective trim and a built-in eyewear wipe round out the ride. Made with Bluesign-approved materials, the Trail 4. 0 Long Sleeve is a sustainable choice for rides when you want a little more coverage.
