Size: M The technical Sleeveless Base Layer offers maximum comfort through the warmer months of the year. The lightweight, anatomically-fitted mesh garment is extremely breathable and effectively disperses moisture to regulate your surface body temperature and keep you dry. Using a soft and lightweight fabric, this base layer looks and feels invisible under your jersey. The elastane component allows the base layer to stretch to your body’s shape in even the most aggressive riding position while remaining highly breathable and comfortable against your skin. The open mesh pattern promotes the evaporation of sweat during harder efforts, creating a natural cooling effect that helps maintain an efficient body temperature.
