The Swix TRIAC RACE X M men's functional top with long sleeves is suitable for high-intensity trainings. It is made of three different fabrics, which are joined by single-layer flatlock stitching from edge to edge to form one super elastic unit. The lighter fabrics are used in areas that heat up more, while the more exposed front and shoulder areas use more insulating brushed fabrics that wick moisture and sweat away from the skin's surface, leaving the inside of the fabric feeling dry.
