Product details

The Tree Wool FL T-Shirt by Mammut is a functional shirt specifically designed for outdoor activities. It combines the benefits of merino wool and lyocell, a biodegradable fiber derived from sustainably sourced wood. This innovative material blend provides excellent breathability, quick drying, and optimal temperature regulation, making the shirt comfortable to wear in both cooler and warmer conditions. The odor-neutral properties of the natural fibers make it ideal for longer outings, whether hiking, climbing, or on ski tours. The loose fit not only allows for freedom of movement but also gives the shirt a casual look that is suitable for both nature and everyday wear. The Tree Wool T-Shirt is thus a versatile companion for active individuals who value comfort and functionality.

  • Made from 50% merino wool and 50% lyocell for optimal breathability
  • Quick-drying and temperature-regulating for maximum comfort
  • Odor-neutrality thanks to the natural properties of the materials used
  • Loose fit for unrestricted freedom of movement
  • Ideal for various outdoor activities such as hiking, climbing, and ski touring.
