French Fitness RevolutionSkull Cap Helmet Liner Running Beanie - Ultimate Thermal Retention and Performance Moisture Wicking. Fits Under Helmets

These skull cap liners are very comfortable. I shave my head so therefore, they are great during winter months as I wear them under trapper hat, ball caps, Beanies, etc. or by themselves in the spring. My first purchase of these liners was back in 2018 as I was taking a flight. I had remembered how in the past sometimes it would get a little cold because of the overhead vents. So I purchased a pair of them, and it was the best thing I did for that flight. I was surprisingly pleased with these liners, back then, and that's why I purchased them again. They are great.

It’s made with durability, colors bright and I love the fit!

The description says, "ultimate thermal retention." I don't know about that, but it's better than the cheap, thin balaclavas. This one is high quality and is pretty thin for the warmth it provides. I wear it under my bike helmet when I ride in the cold. It's probably about 40% warmer than the cheap one I have been using. It works for my short rides. On a long ride in the cold, I would want one of the ones with an aluminum layer.

Fits well. Quick delivery.

Barely covers my ears and I have a small head. If you have any hair good luck

It's a quality product heavy duty wicking material

I have a very small/narrow head to the extent I have more than one occasion found headgear in the largest size for children to fit me just fine. These skull caps are tight on me, if you have and average size head these will be very tight. Other than being certainly on the small side they are lightweight and work well for working out and running in warmer weather if that is what your reason for purchasing is.
