The Activist Tee embodies what we love about Houdini: the practical utilization of a natural fiber, Merino, in a casual, comfortable garment that will perform all day on the trail, on a bike, or on a crag. Made from a blend of mulesing-free Merino (that means cruelty-free) and lyocell (tree fiber), the Activist Tee is softer than typical Merino garments and has inherent odor control, temperature regulating and moisture wicking technologies. If you haven't tried a natural fiber tee for running or other high-intensity activities, start here. You will become a convert.
