The Perfetto RoS is THE perfect jacket in every way. Originally designed as a cold weather training garment and extreme weather racewear for our professional riders, it actually excels in many conditions thanks to its total wind protection, excellent fit provided by its stretch materials and unmatched breathability.

This new model represents the biggest step forward in performance over the previous three generations. The name RoS stands for Rain or Shine. The dry weather comfort is undeniable, but you also get near-waterproof protection in case you get caught in the rain. We worked with Gore to develop two new exclusive Castelli GORE-TEX INFINIUM™ WINDSTOPPER® fabrics. We use a lightweight, fleece-lined waterproof version on the front-facing surfaces and a lighter, stretchier fabric on the back that still offers the breathability of the previous fabric while improving water resistance.

The Perfetto RoS is therefore an ideal thickness. It does not have any built-in thermal insulation, which leaves you the possibility of adding a light technical underwear in moderate conditions. You can also wear a thermal jersey underneath and use it when it is very cold. It's up to you.

All the hallmarks of the Perfetto family are here: excellent fit, easy-to-use YKK® zipper, longer rear protection to protect against wheel spray, reflective panel on the back and a discreet style that makes you forget it's a racing jacket.
