A staple of the sponsored teams and year round racers. This embroidered fleece hat has warmed heads during cyclocross course setups, warmups, spectating, road podiums, cross podiums, saturday rides, and driveway shoveling. 95% Polyester 5% Spandex. One Size Fits Most. Feedback from customers is that most of us with larger heads have not been able to find hats that work and yet this one fits great.
