Mammut - Tree Wool Thermal FL Half Zip Longsleeve - Sport shirt

Stay warm without overheating

The Tree Wool Thermal FL Half Zip Longsleeve by Mammut is a versatile performance shirt for demanding mountain tours. Its blend of temperature-regulating merino wool and soft fabric keeps you comfortably warm in the cold without letting you overheat when the pace picks up. In changeable mountain weather in particular, this shirt helps you maintain a balanced body temperature, making it ideal for long, demanding days in the Alps.

Stretch fabric moves with you

With its stretch fabric and regular fit, this top gives you complete freedom of movement, whether you’re climbing, reaching or out on the trail with poles. The long sleeves protect your arms, and the shirt layers easily under other clothing. It stays comfortably in place as you move, making it a reliable base layer for any alpine challenge.

Adjust ventilation in a flash

With the half-length front zip, you can adjust ventilation in a flash without having to take the shirt off. The stand-up collar protects your neck from the wind and ensures comfort during breaks or in draughty conditions. Especially when the weather changes in the mountains, these details offer you flexibility and protection – so you can focus entirely on your adventure.
