For those riders who want to wear a cap on warmer days we created the A/C Cycling Cap. The upper is a lightweight polyester mesh that wicks moisture, allows free flow of air, yet provides some sun protection at the same time. Weight: 33 g

A thoroughly modern take on a traditional-looking piece. We use a merino wool layer over a polyester jersey liner — the wool provides insulation and pulls the moisture away from the skin. The forehead and earflap are double layered for warmth, while the cap is thin enough to comfortably fit under your helmet. One Size

WARMTH THAT FITS UNDER A HELMET Castelli's original Difesa cap is a Windstopper piece that's best for extreme conditions. With the Difesa Thermal they removed the windproofing, but by doing so dramatically improved moisture management, so it's best for cool to cold conditions, especially with high-intensity riding. They placed a rib-knit wool wrap around the ears to keep you warm but keep it all relatively thin to fit under a helmet. Weight: 52 g
