Simple, functional and simply brilliant - the Women's Activist Base Tee by Houdini! The functional shirt is made of an environmentally friendly material blend of merino wool and tencel - fast growing, renewable raw materials that are biodegradable and sustainably processed. The plant-derived tencel makes the shirt very soft, guarantees it wont itch and is also slightly cooling. Merino wool provides a fantastic climate on the skin which wicks moisture outwards. It also keeps warm even when wet. Its antibacterial properties work to suppress bad odors. Flat seems prevent chafing and pressure points on the skin. Skiing on cold days, climbing in the summer or simply going for a walk - the Houdini Women's Activist Base Tee is always the right choice for active women! ;"
