With a design that's a slightly different take on the traditional cycling cap, the Castelli Prologo 3 Cap will set you apart from the rest of the field. Simple, yes, but beautiful. And, as we've written countless times, quite practical. Shield your skull from the sun, protect your eyes from both the sun and rain, warm your noggin after finishing a race, keep sweat out of your eyes when mastering your spin on the rollers indoors. Wash them in the machine; so long as you keep them out of a hot dryer, they should last and last and last.

The Prologo 3 cap is 100% cotton. It's a traditional four-panel pro design, with the Italian tricolore on the brim. Castelli logos are screened on the stripes that run around the crown.

The Castelli Prologo 3 Cap comes in the following colors: Ocean, Black, White, and Yellow Fluo. One size fits most.

It's a hat

Great fitment under my helmet and does a great job keeping sweat out of my eyes. Machine washable is a plus.
