Sayonara sweat.

Nothing gets as tiresome as summertime sweat dripping into your eyes on a long ride. Castelli has a remedy in their Summer Skullcap. It's made to fit nicely underneath your helmet, with an airy mesh construction in the top portion. The main working part of the skullcap is the absorbent headband. It wicks moisture from your skin before it can accumulate and drip into your eyes. Also consider this -- the mesh top acts to block the sun from your scalp. So if you have a helmet, like the Giro Aeon, with big vents and lots of them, you might consider this a nice form of protection if your hair isn't what it used to be.

The Castelli Summer Skullcap is White w/red and comes in one size.

  • Cooling mesh top
  • Absorbent headband

I am a novice road rider in South TX, this cap is thin and breathable and fits nicely under my helmet. It did a good job of absorbing sweat. I would like it to fit a bit tighter, but otherwise a well made cap.

Work remarkably well

These aren't perfect, in terms of handling sweat, but it has decreased the problem of sweat in my eyes by about 90 percent...and that's pretty good. They also appear pretty durable, as I've washed mine a number of times without any apparent wear. My only complaint is the price, these should by about 50% less.

love it

Fits me perfectly (Medium helmets all fit me well) but not a lot of stretch so careful buying if you have a large head or a lot of hair. Very thin and comfortable with flat seams that do not dig into your forehead as many bands do.

Any info on UV protection? Not only am I...

Any info on UV protection? Not only am I looking for something to keep sweat under control but to also protect my bald head from the sun during the summer months.

Responded on

No sure it is provides any UV protection. The top on the cap is mesh so it certainly won't replace sunscreen.
