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. - Thermoflex Core2 fabric on body of cap for warmth and optimal wicking to move moisture away from your skin - Wool-blend ear cover - Classic fit with vintage appeal

DO-IT-ALL DILUVIO We've taken our best-selling Diluvio C and Diluvio Allroad booties and modified, improved, and combined them into the all-new Diluvio UL. With improved fit and a better seal thanks to the neoprene enclosure at the top, large reflective rear tabs for visibility, and the flexibility to accommodate any type of cycling shoe, there's little this bootie can't handle. - 3mm neoprene for water protection and warmth - Velcro closure underfoot for the perfect fit - Bottom opening accommodates road, gravel or MTB shoes - Sealed seams - YKK zipper - Neoprene skins at cuff to keep water out
