To perform during the most intense rides, the form fitting Chrono SL Base Layer manages perspiration, features extra insulation, and will keep you doing what you do best. The key to temperature regulation in cold weather is perspiration management. Giro designed the Chrono base layer with their proprietary wikpro fabric to keep you warm, dry and comfortable in the coldest conditions. Wikpro is a proprietary blend of polyester and nylon knit that enhances moisture transfer while staying soft against the skin and providing great rebound and fit. This is the same fabric proven in our popular Chrono Base Layer, but constructed in a heavier weight for extra insulation. This next-to-skin garment is the foundation for a comfortable experience in the elements.
UPF50+: A garment with a UPF of 50 allows just 1/50th of the sun's UV radiation to reach the skin, helping to protect skin against damage from the sun.
WikPro Farbic: WikPro fabric is a proprietary blend of polyester and nylon knit that enhances moisture transfer with an incredibly soft feel against the skin, and exceptional stretch.
