ErgodyneChill Its 6632 Cooling Skull Cap, Sweat Wicking Liner, UPF 50 Sun Protection

Great as a helmet liner or just to keep balding head warm, cool or sunblocked. Very comfortable. Appears well constructed.

I wear this under my headphones for yard work. Does the job well and keeps the sun off my head.

This skull cap does a good job of wicking away sweat and keeping it out of my eyes on summer MTB rides in a hot and humid climate. It's a one-size product and the fit is just not great. I'd rather it fit snuggly and stretch over my head. But this one has a top breathable panel which has very little stretch so it doesn't pull tight across the crown and leaves fabric bunched right around my helmet band.

If you have to wear hard hats or other PPE and have issues sweating, look no further.I am a big guy, and the job I was assigned to at the time of this purchase work was a construction site with no AC and very little air flow. Hard hats were required. In no time at all, I would be sweating profusely and it would get in my eyes. I constantly had to stop what I was doing to wipe it away. Then I bought this. It fits perfectly under my hard hat, fits my big head just fine (I wear a 7 3/4 size hat), and best of all, it kept my head relatively cool and kept all sweat from running down into my eyes. Cannot recommend this enough. It is worth the money.

I like that this cooling cap works. I do not like how tight it is. This cuts the blood circulation off to the top of my head, which I do not care for, but it does work to keep the sweat out of my eyes and it does work to keep my head cool when it is wet.

Color was gray and it fit perfectly

Great value. I have bought two of these inexpensive caps and have worn them on trail runs and a 50k. Fits great in wind and mostly keeps the sweat out of my eyes, although not quite as effectively as a headband (but no headache like you can get from a headband).

It is very comfortable.
