The Radiator SL base layer is our mesh ultralight summer base layer, designed to be worn in conjunction with our jerseys and bib shorts for the best combination of comfort and performance.
A totally new take on the summer base layer, the Radiator uses a unique mesh fabric developed by Polartec, made of polyester and a natural fiber derived from wood pulp called Tencel. The fabric regulates body temp far better than synthetic fiber alone. Hence, the Radiator keeps you comfortable through evaporative cooling, by absorbing moisture (Tencel) and drying (polyester) over the surface. The result is a supremely comfortable base layer that performs throughout the summer months and warm to hot climates.
Tag free collar, minimal strategically placed flatlock seams and self binding edges mean a base layer that disappears around you. Designed to fit close to the body with enough stretch for total mobility.
