Keep Your Ears Warm, Even During Freezing with the Castelli Pro Thermal Headband

Searching for just that additional make-or-break garment that will keep you warm without a hitch? Look no further than the Castelli Pro Thermal Headband. The design works hard to maximize comfort all ride long so you can make the most of the cold-weather months.

This state-of-the-art cycling band utilizes a construction of the ultra-stretchy Thermoflex, a material that remains soft to the touch no matter what. A progressive design features flat-lock stitching and a raw-cut edge so this headband lies comfortably under your helmet without bunching — so you barely even notice it's there.

Tried and tested technologies take this garment to the next level, including a finishing touch of extra reflective details that keep you highly visible in low light conditions. The next time winter tries to keep you off the bike, fight back with the gear that's ready for the long haul.

    A great product
    by Shelley

    Two teenage boys in my life ride their bikes to school every day. As the weather got colder their helmets weren't sufficient to keep their ears warm and their hats didn't fit under the helmets. When I spied them riding with their hats and no helmets I did some research and found your product. The headbands worked and now the boys are compliant with their helmets. It also came after a brief lecture on the dangers of riding the city streets without head protection. Great product!

    warmer than they look

    Comfortable and warm when you want to keep your ears out of the wind. If I need something like this I usually wear a cap, but if I am uncertain I have this in my pocket.

    My go-to for the chill

    Very light weight, very thin, and perfect protection from the chill. I mostly run with it, some bike, some XC skiing and snowshoeing, I just love wearing this. Doesn't get sweaty soggy like heavier fabric and has good stretch so it's comfortable-not tight and not sloppy loose.

    Thin and effective

    I was looking for a thin headband. My helmet is snug and won't allow anything even remotely bulky to be worn. I also have hair (lots of it...thanks, Covid) and don't really feel the need for full coverage. This fills the bill nicely.
