  • Familiarity: I've put it through the wringer

Very warm yet breathable. I wear it down to 25deg. Lower than that I stay home!

Skully that works!

  • Familiarity: I've used it several times

This thermo skully really works well in temps ranging from the 30's to 50's. I'm really glad I bought this, worth every penny!

Nice looking cap

Comfortable cap. I have worn it in temps down to the lower 30's and it did a decent job. My ears get cold very easily and they have been ok so far. Not toasty, but ok.

Love, Love, Love It

Sleek under the helmet and toasty, too. As a bald man, I can't imagine cold-weather riding without it. A great find at a fair price. Indispensable.

Great Skully!

I love this thing. It provides just the right amount of warmth without being buikly under your helmet. Plus, you can wear it on its own and look pretty cool!

Bravo Style

My wife loves it. She wears it riding in the cold. She wears it to the gym. To yoga. Stylish and cool. Bravo Castelli.
