Our most popular jersey, thanks to the warmth and excellent moisture management of our Warmer brushed-fleece fabric; the clean, purposeful design; and the large reflectivity panels on the chest and below the pockets on the back.
The Perfetto ROS LS is back in stunning new colors, crafted from repurposed fabrics, solidifying its place as one of Castelli's most iconic cycling jackets. Designed for professional cyclists and everyday riders, it combines advanced GORE-TEX INFINIUM™ WINDSTOPPER® technology for full wind protection and excellent breathability. With a perfect fit, lightweight feel, and impressive versatility, it performs in both dry and wet conditions. Ideal for cold weather training or unpredictable climates.
Warm, dry, comfortable and very soft. This base layer feels warm from the moment you put it on. The best choice for cold-weather riding.
Made to keep you dry in cool conditions, this base layer features body mapping construction with Prosecco hydrophilic treatment on the main body fabric and lighter-weight PrimaLoft® fabric aligned to the parts of the body covered by the bibtight straps.
Made to keep your core warm while providing enough ventilation to keep you from overheating. Brushed fleece inside for warmth. Stretch side panels keep it fitting perfectly.
In cool conditions the mesh construction gives the warmth of wool but won't wet out on high-intensity rides.
Castelli's best-selling jacket is also the ideal gravel jacket in cool and cold temperatures. It's the same Perfetto RoS Long Sleeve jacket but with a graphic that we think works well both on and off-road.
