Giro's Chrono Base Layer regulates your core temperature when the going gets cold.

The key to temperature regulation in cold weather is perspiration management.

Giro designed the Chrono LS Base Layer with our 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 SL 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.


Construction: Seamless construction, Made in Italy

Fabric & Construction: Wikpro material, 60% nylon / 30% polypropylene / 10% elastane, 180 g/m2

Fit Notes: Formfitting
