Swix RaceX Bodywear has won countless tests over the years. The products are designed for high-intensity activity and are the preferred baselayer for many sportspeople due to the light and elastic fabric. RaceX Warm contains Merino wool and is therefore suitable for slightly colder temperatures. The fabric is highly elastic with 4-way stretch and has anti-chafing seams. The open structure of the fabric holds a thin layer of insulating air against the skin, while offering outstanding breathability and ventilation properties. The material absorbs moisture effectively from the skin and is one of the reasons why the baselayer feels so comfortable and thermo-regulating during intense activity. In addition, the material is fast-drying.
