Old school meets new with this new twist on a classic design. Take the classic winter cycling cap and add modern material and improve the fit and you get Capo's Thermo Roubaix Winter Cap. The core of the cap is constructed from Thermo Roubaix. Its hollow cores regulate temperature without excess weight or bulk and does a great job of wicking moisture. A winter cycling cap is a perfect application of this fabric. The bill helps with sun and glare while the flaps keep your ears warm. The flaps also flip up so the Roubaix Winter cap can be worn in warmer conditions. One size fits all.
