Why We Like The Castelli Alpha Flight RoS Limited Edition Jacket

When winter temps blow in, we roll out wearing the Castelli Alpha Flight RoS Limited Edition Jacket. The performance fit and raw-edge hem keep us streamlined, while the Polartec Alpha insulation offers our chest, back, and arms moisture-managing warmth. As we pick up speed down hills, the wind-blocking power of Nano Flex Light in the chest, sleeves, and upper back stops the icy air from chilling our bones. And when we’re pushing up the next climb, the double-layer construction lets air move through to keep us from overheating. 


  • Highly breathable thermal jacket for your cold-weather rides

Great colder weather jacket

I've used it several times

Excellent insulation and wind-blocking material. Its streamline fit feels light and very non-restrictive. With bayer layer and long sleeve shirt, I was comfortable in mid to upper 40's. I'm 5-9" and 140 lbs. with athletic build and XL firs nicely.
