The long - sleeve Perfetto is an incredibly versatile cycling jacket. It offers 100% wind protection with GORE - TEX INFINIUM™ WINDSTOPPER® water protection and top - notch breathability. Wear it with a light base layer in mild temperatures or add a thermal layer when it's below freezing. If you can only have one jacket in your cycling collection, this is the one. The Perfetto RoS does it all. Originally designed for pro riders in cool - weather training and extreme - weather races, it performs well in various conditions. Thanks to full wind protection, a great fit from stretchy fabrics, and excellent breathability, it's a top choice. The current version is a big upgrade from the previous four generations. The 'RoS' means Rain or Shine, emphasizing dry - weather comfort but also providing near - waterproof protection in the rain. Castelli worked with Gore to develop two exclusive GORE - TEX INFINIUM™ WINDSTOPPER® fabrics. The front uses a light fleece - lined water - resistant fabric, and the back has a lighter, stretchier one that boosts water repellency while keeping breathability. It has an ideal weight with no built - in insulation, so you can layer as you like. The jacket features an excellent fit, an easy - sliding YKK® zipper, a long tail to block wheel spray, a reflective panel on the back, and a discreet style. It's a must - have for every cyclist. Product features include Castelli exclusive GORE - TEX INFINIUM™ WINDSTOPPER® 205 Warm brushed water - resistant fabric on the front, GORE - TEX INFINIUM™ WINDSTOPPER® 203 Stretch on the rear for extra stretch and breathability, taped shoulder seams (reflective for color 085) for more rain protection, a YKK® Vislon® zipper for easy sliding and extra wind/rain protection, a zippered ventilation opening on the chest side, 2 rear pockets with a pump sleeve accessible with gloved hands, a Gabba - style dropped tail with a large black reflective panel, a weight of 337gm, a temperature range of 4°C - 14°C / 39°F - 57°F, and a performance fit.
Using the Castelli Perfetto RoS Jacket is straightforward. In mild weather, just pair it with a light base layer. When it gets colder, add a thermal jersey underneath. The zippered ventilation opening on the chest side can be opened when you start to feel too warm during your ride. The rear pockets are easy to access even with gloves on, so you can keep your essentials like your phone or energy bars there. As for care, follow the washing instructions on the label. Usually, a gentle machine wash with cold water is best. Avoid using harsh detergents that could damage the GORE - TEX INFINIUM™ WINDSTOPPER® fabrics. After washing, let it air dry. Don't put it in the dryer as high heat can affect the performance of the fabric. Check the taped shoulder seams regularly for any signs of wear and tear, especially if you often ride in wet conditions. If the reflective panel on the back starts to fade, be extra careful when riding at night and consider getting a new jacket for better visibility.
