    Summer Skullcap

    Grinding up your local hill o’ death is hard enough when you can see where you’re going, but when you find yourself blinded by sweat, it’s time for the Castelli Summer Skullcap. Carefully constructed to sit smoothly under your helmet, the Skullcap combines a sweat-absorbing headband with a cooling and wicking mesh top to keep your focus on the ride, not on the sweat that’s stinging your corneas.

    • Hot-weather skullcap that keeps sweaty discomfort at bay
    • Wicking mesh material breathes well and pulls sweat from skin
    • Form-fitting construction fits neatly under your helmet
    • Item #CST00CB

    Ok but

    • Familiarity: I returned this product before using it
    • Height: 6'2"
    • Weight: 250lbs

    It is a one size unisex. It fit over my head but after a while it would just shrink back to its original size, and in shrinking, it would slip off my head. In short, it would not stay put. It seems to have worked for others but it did not for me and my quite bald head. Thank you

    Essential item if you are bald

    • Familiarity: I've used it several times
    • Fit: True to size
    • Height: 5'11"
    • Weight: 148lbs

    This is a very lightweight skull cap that looks good and fits well. I started to wear this under my helmet to avoid the turtle shell pattern that develops on my bald head on sunny days. One added benefit: no more sweat dripping down the inside of my sunglasses.

    Favorite for Warm Rides

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    The Castelli Summer Skullcap does exactly what it should under a helmet for riders (like me) with short or thin hair. It keeps sweat out of they eyes and off the glasses lenses, and keeps the sun off the scalp. The cap is nice and thin and all the stitching is flat-lock, so there is never any extra pressure or discomfort. It cools really well, to the point that it can feel chilly in temperatures under 65 or 70 degrees Fahrenheit. I have a couple of these!

    Great fit and feel

    I have a big head, and this thing fit just fine. It is nice to have one that is black because it doesn't show like a white one does through my helmet vents. I suppose in the summer it might retain heat from the sun, so I'll go back to my white ones exclusively for those months. I've owned previous versions of this brand and they've lasted through countless washings. Solid value and performance.

    better than headsweats

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: one size
    • Height: 5'9"
    • Weight: 150lbs

    I have worn headsweats for years. This is a lot better material and quality. It does fit a little snug, I have a medium size head. I wear this to shelter head and thinning hair from the sun.

    Love - Hate

    • Fit: Runs small

    I love most ALL Castelli cycling wear, and own tons of it, from Alpha, Sorpasso tights down to several short sleeve jerseys and bib shorts, gloves, even toe thingys. But this Summer Skull Cap has way too much Lycra in it. It took both hands (wishing I had a third) just to stretch it out over my head. Once on it just wanted to pop off. Might work if you have a small head, mine's large (58 cm circumference) so this went back. Going to buy another Headsweats Eventure Skullcap in white to complement the one in red I already own.
