Castelli has offered some great cycling cap options the last few years, but with the Endurance Cap the Italian company has returned to the roots of cycling. Here is your traditional cotton cycling cap done right. The fabric is piece dyed for a rich depth of color that wont degrade after a few washes. It has a center stripe as tradition dictates, but in a tasteful tone-on-tone coloring. The one size fits all calp features a stretchy rear band section for flexible fit and comfortable fit. A small scorpion and Castelli wordmark on the side show that you know your cycling heritage.
