Features: Made of washable wool blended with nylon cooling yarn that provides a continuous cooling sensation and absorbs and desorbs moisture.The temperature regulating function of wool allows you to feel warm when it's cold and cool when it's hot, and it also has a unique soft texture. We have created boxer shorts that can be used year-round, from all kinds of outdoor activities to daily use, while maintaining the same benefits such as odor resistance. The thick waistband that feels comfortable against the skin features the slogan "LIGHTING YOUR WAY" and the elevation map of Japan's leading trail running race.
