Houdini M's Activist Tee

The M's Activist Tee by Houdini is a versatile T-shirt suitable for any occasion—whether for everyday wear, work, hiking, climbing, or leisure. Made from Activist TreeMerino™ wool, it combines the softness of merino wool with effective moisture management. This innovative blend of merino wool and Tencel fibers ensures a breathable, quick-drying fit that feels comfortable against the skin.
A special feature of this T-shirt is its natural resistance to bacteria and dirt, which means it doesn’t need to be washed after every wear. This helps preserve the material and extends the garment’s lifespan. The M's Activist Tee is also odor-neutral and adapts to body temperature, making it an ideal choice in both cold and warm weather.
The T-shirt’s relaxed fit makes it easy to pair with both jeans and hiking pants, making it the perfect companion for a minimalist lifestyle. Whether worn as an extra base layer in winter or as a lightweight top in summer, it offers versatile comfort and functionality all in one.

Care instructions

  • Use our wash bag to protect your clothes.
  • Machine wash cold, preferably with a wool program.
  • If possible, use wool detergent. Otherwise, mild, environmentally certified detergents and be sure to use the correct dosage. Choose a detergent that contains a neutral pH and no enzymes.
  • Avoid the use of bleaches and alkaline substances that increase the pH. As well as the use of enzymes such as protease or amylase, as they can degrade the wool that gives the material its natural performance properties. This also applies to silk.
  • Avoid fabric softener. This is not only harmful to our environment, but also negatively affects the performance of clothing, especially moisture transport and breathability.
  • Do not tumble dry.
  • Shape the garment after washing and lay flat to dry.

Technologies and manufacturing processes

  • Activist TreeMerino™ wool

    Optimal organic solution for the future. Softer than pure merino wool and with active moisture management.
  • Wool material

    Wool is a fantastic material with natural resistance to bacteria and dirt. Therefore, wool does not need to be washed after each use. Frequent washing negatively affects the properties of wool and wears out the garment unnecessarily. Instead, air your wool garments to reduce water consumption, save energy and extend the life of the garment.
