Top off your winter kit.
As winter rolls in, we tend to get excited about the big, flashy items like the Alpha Jacket or the Sorpasso Bib Tights. Meanwhile, the less-readily apparent things like toe and ear protection slip under the radar right up until we realize that no amount of Windstopper fabric on our chest will keep our delicate extremities warm. That's what the Castelli Risvolto Winter Cap is for.
The Risvolto's Strada Thermo fabric literally means warm road, which is kinda the exact opposite of the circumstances you'll want it for. But whatever. The material keeps you warm, and its wicking properties are supplemented by an additional lining for even better moisture transfer. The ear flaps from which the Risvolto takes its name stow under the hat when you don't want them, and they're cut to accommodate a cycling position when you do.
The Castelli Risvolto Winter Cap is available in one size in the colors Black/white, Grey/black, and Moonlight Blue/red.
