The Woolpower Briefs Xlong W's Lite are knee-length briefs in a boxer design. They are elastic and highly functional - in other words: fast-drying and temperature-regulating. The proportion of functional fibers increases the durability and service life of the briefs. The merino wool ensures odorless, scratch-free comfort and regulates the heat and moisture balance. A soft, elastic waistband with knitted logo ensures a perfect fit. The Briefs Xlong W's Lite warms when it's cold and cools when it's warm.
