WHAT IT IS / PRODUCT FEATURES Our best jacket for mild winter conditions. This lightweight, super breathable and extremely fast jacket is great for high intensity rides or when you want to maintain your optimum temperature in cold conditions. Alpha construction with a membrane-free outer layer and Polartec® Alpha insulation inside
Woven Nano Flex Lightna fabric on the chest, sleeves and upper back partially protects against wind, but the absence of a membrane ensures maximum breathability
Two-layer Alpha construction separates the windproof and insulating layers for better ventilation and thermoregulation.

This is the jacket for a quick ride in cold weather, or if you want to dress just right in transition. What makes this jacket work in full effect is our Alpha double-layer construction, which will have you race ready right at the start of spring. The stretchy fabric of the top layer lets in some air so you don't sweat as much when you're riding hard in the cold, because when you're wet, you'll be cold. The inner layer of Polartec® Alpha insulates, but is breathable enough and so lightweight you won't even know you're wearing anything.
We made the backpack from our Nano Flex Extra Dry, which insulates solidly, but because it doesn't have a membrane it breathes great and sweat can evaporate quickly. The cut is on the body so nothing flutters in the wind, and little details complete the whole: smooth-running YKK® zippers, reflective elements and drainage holes on the pockets, a flat silicone waistband. The precise fit makes this our most aerodynamic jacket. Not that aerodynamics are all that important in winter, but at CASTELLI we believe that speed is fun.
