More Information

Mammut’s Men’s Lenni Shirt is a classic hiking shirt that earns its place when you want one piece that works for both quick local hikes and longer trekking days. It’s the kind of shirt you can wear start-to-finish on a trip without overthinking layers or comfort.

This latest version keeps the familiar, high-performance lightweight feel, but updates the fabric to a new low-impact material. In use, it dries fast, manages odor to stay more pleasant over repeated wears, and gives reliable sun protection for the areas it covers. A regular fit, back movement fold, and a buttoned chest pocket round out the details you actually notice on trail.
