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

Works great under hardhats to help keep sweat out of your eyes. Light comfortable and keeps you a little cooler if you soak them on hot days

This works great under a motorcycle helmet to not let sweat get into the foam in your helmet. When it gets dirty, just toss it in the washing washing machine with the rest of your stuff. However, (very important)...do NOT toss it in the dryer. The heat in the dryer will booger up the elastic in the head band and it will not fit right anymore. Just hang it up somewhere and let it air dry. I ruined 2 of these by tossing them into the dryer and the thing that irritates me about it is that nothing is said about this on the packaging. I never complained to the seller and just chalked it up as my ignorance, but the one that I have now has been thru the washer many times with no issues and the elastic is just as it was when I took it out of the package. Good product and a good, fast shipper.

Made entirely of very thin polyester fabric that is 8% spandex in the sides for stretch and 100% polyester on the mesh top. Light weight and perfect for under helmet/hard hat use. While I prefer terry cloth sweat band welder hat styles. They often are too thick for non adjustable helmet use. That is the opposite with this. Only a very thin elastic band, with no bulk serged t-shirt style seams. Perfect for under lining. Also for training wet hair after taking a shower.

works great for playing games in the sun and heat, comfortable and lightweight

protects from sun or cold. comfortable even with large head. used under bike helmet. keeps bald head warm inside in winter too. seems well built.

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.

If your hardest starts to get kinda funky after years of wear this will help. Had a couple of months and still has it’s elasticity. Some other ones begin to stretch out. This one fiesnt

For cyclists who spend a lot of time in the saddle,Even if you wear a helmet these are a must-have to keep the sun off your head. I wear them in the hottest temperatures and have no problems.
