A cycling base layer is the beginning of any great day riding. Base layers help regulate body temperature, wick moisture, provide insulation, or aid compression, ultimately aiding performance on the bike.
Castelli’s premium range of cycling base layers covers all seasons and conditions from glorious hot summer days to the coldest winter weather. Summer base layers are designed to provide ample wicking and cooling. They are lightweight and tend to be either short sleeve or sleeveless and made of mesh fabric. Winter base layers are most often long sleeve and made of fleece that insulates against the cold. For Spring and Autumn base layers Castelli uses its ProSecco mid-weight fabric that keep things dry while providing some insulation as well.
