Elite Sun Protection and Sustainable Performance for High Alpine Days

The Mammut Men’s Selun FL Sun Hoody is a technical essential designed for athletes who spend long, high-exposure days on the rock or the trail. Engineered to minimize the need for sunscreen while maximizing airflow, this hoody is built from 100% recycled polyester that offers a UPF 50+ sun protection rating. The lightweight, stretchy knit fabric is treated with a bio-based HeiQ Fresh anti-odor finish, which effectively neutralizes odors without the use of silver, ensuring you stay fresh during high-output summer mountaineering or multi-day trekking.

Functionality is integrated into every seam. The Selun features offset shoulder seams to eliminate pressure points and prevent chafing under backpack straps, while the integrated thumb loops and high-collar hood provide total coverage for the neck, face, and hands. A standout feature is the solution-dye manufacturing process, which uses up to 90% fewer chemicals and 85% less water than traditional dyeing methods. This makes the Selun FL Sun Hoody a reliable, high-performance choice that is as kind to the planet as it is to your skin.
