WSHSTSMesh Dry-Fit Helmet Liner for Men Women,Cooling Skull Cap Moisture Wicking Breathable Summer Head Beanie

I bought these to hold my longish hair in when I was spray painting my home. They are kind of slick and they often just slipped off my head probably because of my hair. I think they would work well if you had really short hair maybe...but they did the job i guess and the price is good.And you can look like that guy from U2.

Very light. I don't even notice that I am wearing the liner under the helmet. I have a L/XL and it fits perfectly. I washed it in the washing machine without any problems.

I use the liner when working outside in the heat. It does a great job of keeping my sweat out of my eyes.

I use these when I wear my CPAP and have noticed less hair loss - keeps head cool!

Nice

Gigantic cap could fit a soccer ball

Way too small

Perfect for what I needed
