The long-sleeve Gabba is one of our 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. Sublimation print graphic on the do-everything Perfetto RoS 2 Jacket base Castelli-exclusive GORE-TEX INFINIUM™ WINDSTOPPER® 205 Warm brushed water-resistant fabric on front-facing surfaces GORE-TEX INFINIUM™ WINDSTOPPER® 203 Stretch on rear-facing surfaces for greater stretch and breathability Taped shoulder seams for extra rain protection Top- and bottom-opening YKK® Vislon® zipper for easy sliding, covered for additional wind and rain protection Zippered ventilation opening on side of chest 3 rear pockets Reflective panel at bottom of pockets. The Unlimited version of the Perfetto RoS 2 Jacket is simply a graphic treatment making it look more at home on any surface but not sacrificing any of the performance. When we think about what we want in a gravel jacket, we keep coming back to the Perfetto, since it really is perfect for so many conditions. We just want it to look different. The Perfetto RoS 2 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. There's a light fleece-lined water-resistant fabric on the forward-facing surfaces and a lighter and stretchier fabric on the back that maximizes breathability while providing excellent water repellency. 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 new model has a touch more room through the chest, shoulder, and biceps. This is the one jacket that belongs in every cyclist's quiver.

Castelli's best jacket for mild conditions, with front wind protection, light insulation, maximum breathability, and water repellency to keep you dry in mist, light rain or spray from wet roads. This is a Castelli staff favorite thanks to the wide temperature range, fit and versatility. GORE-TEX INFINIUM™ WINDSTOPPER® 150 fabric on front and sleeves for wind protection with high breathability and effective rain protection Nano Flex Xtra Dry on back for more ventilation allows heat and sweat to escape while shedding rain thanks to a nanotechnology water-repellent finish Alpha double-layer construction separates windproof layer from insulation layer, allowing better ventilation management Inner layer in ProSecco Strada for lightweight insulation with effective moisture management Double YKK® Vislon® front zippers Zippered secure side pocket for valuables 3 rear pockets with reflective laser-cut drain holes Raw-edge waist lies flat and moves with you. This jacket is about the art of dressing just right for cool conditions. We're talking about those days when you need some protection from the cool air but not enough to bring out the winter jacket. Overdress and you'll be sweating and get cold because you're wet. Underdress and you never fully warm up to enjoy the ride. The concepts behind the construction are fairly simple: wind protection on front-facing surfaces, highly breathable fabrics on back-facing surfaces, and all-around water repellency in case you get a few drops of rain. But what makes this jacket spectacular is how we executed these simple concepts. The wind protection comes from our GORE-TEX INFINIUM™ WINDSTOPPER® lightweight two-way-stretch fabric that moves with you while being so light you'll hardly notice it's there.This light wind layer is backed by a separate ProSecco Strada inner layer with a separate zip that can be opened independently for perfect ventilation control. The back is made from our Nano Flex Xtra Dry fabric that provides a good level of insulation yet has no membrane so allows for ample amounts of sweat to escape. The fit is close to body so there is no fabric flapping around, while the little details make the difference: easy-sliding YKK® zippers, reflective drain holes on the pockets, a lie-flat silicone gripper band around the waist. All these features are why this jacket is consistently named a favorite among Castelli staffers. We think it will be one of your favorites too.

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.
