The Perfetto RoS 2 is the one jacket that does everything well. If you look carefully, the Perfetto RoS 2 Jacket is essentially a long-sleeve version of the Gabba RoS 2. So it's just a warmer Gabba? Not really.

• The full sleeves fully turn it into a jacket, but one that covers a wide range of conditions. Like the Gabba, the RoS insignia signifies that it excels in dry conditions thanks to the high breathability, as well as in wet conditions thanks to the Castelli-exclusive GORE-TEX INFINIUM™ WINDSTOPPER® fabrics.
• The Perfetto RoS 2 Jacket keeps all the cold wind out while being much more breathable than the typical polyurethane membranes used on most jackets that try to compete with the Perfetto.
• When you stay drier, you don't need as many layers underneath. The beauty of this jacket is that it doesn't have any insulation on its own, so a thin base layer is just right for mild conditions, while adding an insulating layer (a thermal jersey or Castelli's Alpha 2nd Layer) will take you to cold temperatures. You decide.
• The ''2'' part of the name refers to the updates to the latest version, including a YKK® Vislon® zipper with both top and bottom openings for more adjustable ventilation.
• The reflectivity on the back is more visible, the seam at the top of the shoulder has been moved to the back, and the three pockets hold more gear.
• While the Perfetto remains decidedly a performance fit, the model has a touch more room through the chest, shoulder, and biceps. This is the one jacket that belongs in every cyclist's quiver.

What it is?

• The long-sleeve Gabba is one of the most versatile pieces. 100 % wind protection with GORE-TEX INFINIUM™ WINDSTOPPER® water protection and best-in-class breathability. With a light base layer it's good for mild temperatures, or with a thermal layer you can ride it below freezing. If you have just one jacket in your cycling wardrobe, this should be it.

GORE-TEX INFINIUM™ WINDSTOPPER®

• Gore-Tex® garments provide total wind protection and maximum breathability. The windproof membrane keeps you from getting cold due to windchill, but the optimum breathability prevents overheating and moisture accumulation by allowing sweat to escape easily. Water repellency is ensured by the DWR treatment applied to the outer fabric.
