Skull Cap Helmet Liner Beanie, Cooling Mesh Cycling Running Hat for Men Women, Fits Under Helmets

They fit perfect, they keep your head nice and cool ,very comfortable.

I wear this under my helmet when mountain biking and it works great. It says one size fits all which I was skeptical about as I have a very large head (7 3/4” hat size) but indeed it fits well and holds in the sweat perfectly!

I am bald and use a CPAP machine. The CPAP mask I use leverages pads at the forehead and at the base of the skull, and the nasal interface comes over the top of the head. I would breakout at the pad points of the mask and thought a skull cap might prevent the break outs. The good: These caps are cheap and light. Fits my large head and doesn't get out of position easily. The bad: Maybe too thin but I can't complain at this price. The Ugly: Nothing ugly at all. Summary: Product is cheap enough to try, order your size and I think you will be happy.

FIT IS AMAZING!! 🤩 Don't worry, one size fit all, and it hugs to your skull perfectly. I highly recommend this product. You won't be disappointed. They have an array of colors but I chose blue and black. Keeps my head nice and cool and warm when it gets cold. 🏆🏆🔥💪😎

These two helmet Liner Benies are perfect. They make wearing my helmet so much more comfortable. The mesh fabric allows the air to circulate so no sweating. As an added benefit - no "helmet hair"!

Good quality and materials, However for me, the skull cap does not go over my ears. If using in a motorcycle helmet this can cause pain on long rides

Nice snug fit. Allows air flow. Provides a feeling of security under the helmet.

The product is very nice - well made, good fabric, good open mesh design, and it stays in place. The only downside - and it's not really a downside if you're aware - is that this is not a wear-alone skull cap. It is small and only covers the top of the ears and the top of the forehead so to keep it in place it needs to be worn with a helmet, cap or other head covering. I wore this as a motorcycle helmet liner for a 100+ mile ride in hot weather and it was very comfortable. Another reason I wear helmet liners is because they cover my hearing aids and the skullcap allows me to put on a snug helmet without affecting the position of my hearing aids. This product works for that purpose. I definitely recommend it but know what you're getting.

I like these and am thinking about ordering more. Light to wear, you don’t even know you are wearing them.

Dear Team Amazon, this product skull cap helmet liner beanie is perfect fit to my skull, high quality stretch material, nice colour. Please display more attractive colours i would wish to buy them also.

Muy absorbentes, evita el molesto sudor en la cara, cuándo andas en bicicleta con el casco. Funcionan perfecto, llegaron en tiempo y forma. El material se ve el correcto, es ligero y no molesta en la cabeza, no lo sientes. Buen producto.

Good item but absorption is not to good.

All good, thanks
