The Desoli Crew is one of the many pieces that Houdini is known for - a 100% mulesing-free (that means cruelty-free) Merino baselayer that's perfect for year-round outdoor activities like hiking, biking, climbing, skiing and any other ______ing you can think of. If you haven't heard the gospel of Merino, it's the ultimate renewable and organic solution in natural performance fibers. With inherent temperature regulating, moisture wicking and anti-microbial properties, you'll quickly become a convert.
