Craft's roots are in Sweden, so you can trust that the Bike Tech Hat is proven both in the lab and the field. In a country where polar nights mean as few as four hours of winter daylight, they know about keeping heads warm and out of the wind. The Tech part of Bike Tech Hat refers to the Flex fleece C232 fabric from which it's made. C232 owes its flex to a mechanical stretch, which means the stretchiness doesn't stem from the materials used, but from the way those materials are assembled. This maximizes the hat's wind resistance by omitting less protective materials in favor of pure polyester. The Craft Bike Tech Hat is available in two sizes, Smallmedium and Largex large, in the colors Amino and Blackbright red.
