Discover the extreme comfort of the Beta RoS Jacket. Made with Polartec® NeoShell® fabric with two-way stretch on the front and sleeves up to mid-forearm, it offers windproof, waterproof and highly breathable protection. The Nano Flex Light fabric on the back offers excellent breathability and protection from light rain and wet roads. Quick-glide YKK® Vislon® zipper, 3 back pockets and large reflective panel on the lower back. Maximum protection with extreme comfort.

NANO FLEX: It was developed exclusively for Castelli: the Thermoflex thermal fabric has been coated with silicone nanofilaments to create the best water-repellent treatment that has ever existed. The water droplets remain on the surface as small spheres and bounce off the fabric without leaving a trace.

ROSSO CORSA: The Rosso Corsa label is applied only to the most technologically advanced products. Rosso Corsa represents a major step forward in innovation and reflects the meticulous construction you expect from Castelli to improve athlete performance.

RoS: guarantees an uncompromising approach to the best garments in dry conditions, almost as water resistant as a rain jacket without sacrificing breathability and ventilation.
