This lightest version of Swix’ test-winning training baselayer is made with panels of even thinner and lighter mesh. This baselayer is optimized for high-intensity activity and is preferred by many due to its light and stretchy fabric. The open structure of the fabric holds a thin layer of insulating air against the skin, while offering outstanding breathability and ventilation properties to prevent overheating. It is a fast-drying material and its structure is designed to absorb moisture from the skin. This is one of several reasons why the baselayer feels so comfortable and temperature-regulating during intense activity.
