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. 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 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. There's a light fleece-lined water-resistant version on the forward-facing surfaces and a lighter and stretchier fabric on the back that maximizes the 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 Commuter Reflex Cycling JacketSimple and stylish during the day, bright and highly visible at night, the Commuter Reflex Cycling Jacket offers excellent waterproof protection day or night. Created for the demands of regular bike commuting, the Commuter Reflex Cycling Jacket fits easily over normal clothing while also having incredible reflectivity that is barely discernible during the day. No odd-looking reflective strips and panels here, just an all-over reflex finish that shines under headlamps and streetlights. This makes it great when you arrive at work and brilliant for regular, non-biking use too. However, it's not just visibility where this jacket shines. The functional fabric also offers outstanding waterproof performance, rated with a 20,000 mm water column to keep the rain out and taped seams to stop any water ingress. Just as important for cycling is its excellent breathability. A 20,000 MVTR breathability rating means less sweat build-up and a fresher feeling when you arrive at your destination. Ventilation comes by the way of a gaiter at the waist, allowing you to seal in warmth or open for extra airflow. The gaiter also allows for a more natural fit with everyday clothing and gives a refined fit both on and off the bike.
