Top-down performance.

If you're like us, then you may be initially skeptical of a simple cycling cap being labelled "performance." Castelli's Performance Cycling Cap lives up to the hype, though, going beyond the typical flip-up bill mounted to a wool or twill body. Instead, it has a flip-up bill mounted to a microfiber front panel that wicks moisture and promotes breathability. The rear panels are mesh, which capitalizes on these benefits by aiding airflow, making this a cap you can wear in the summer to keep the sun out of your eyes.

  • Microfiber front panel
  • Mesh rear panels
  • Flip-up brim

Is size big enough for large head?

I got this cap for my dad for father's day and he loves it. He says it's comfortable, fits great under his helmet, and likes the retro stripes

Great Cap Perfect Color

Keeps the sun out of your eyes! High quality materials as you would expect and the color is great! Matches my brother in law's kit perfectly! Overall would definitely buy again.

IT's a great cap. Wore it for the first time on a 80 mile ride with 9000 vert. Kept the sweat out of my eyes and shaded well when i need it to. never felt like it was to tight and it breathed very well.


Nice Cap

    Definitely an awesome cycling cap by Castelli. Looks great. Works great. And better than cotton caps because it ventilates sweat and heat better because the rear 3/4 is made of a quality fine mesh material.

    But I found the elastic band on this cap sightly tight for my head. I wear a size large in Giro helmets. Strange that the reviewer below thought this cap was not tight enough!

    In sum: this excellent cycling cap is probably best for those who wear a size sm/med to medium bike helmet.

    Order one. If it fits you'll love it!

    Good but not great

    It's a decent cap. The colors and quality are good. When flipped up, the bottom of the bill is red (the cap body is black). The red discolored due to perspiration after the first ride. At least it isn't white. In any event, the reason I am not giving it 5 stars is that it is a little on the baggy side, the top is loose, the elastic band is snug. And i have a large head. I just measured the circumference of my melon and it is 22.5 inches. But i have not had any issues with it blowing off; i just prefer my cycljng gear to be very tight.

    Great cap.

    As a bald guy, I wear a cap under my helmet pretty much all the time to absorb sweat and provide sun protection. The lightweight material of this cap is much more comfortable than a standard cotton cap.
