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

My husband said it's the best he's found in years. It is breathable, light weight. It is stretchy enough but not loose. It feels good.

I bought these to wear at night under my Cpap head gear so that my hair didn’t stick up all day. It works like a charm! It’s not hot at all, and very soft. I forget that I even have it on in the morning. If you have a problem with Cpap hair, then this is what you need.

Fits well and comfortable for my medium sized male head. Well constructed. Works very well while road cycling, due to constant wind exposure. Works well during MTB'ing also. For skating, under my hockey helmet where there is much less wind, it still works well but gets saturated much more than a similar product from Headsweats (the latter however costs more than double.) Note that I sweat a lot and wear glasses; without a product like this my glasses can get quickly covered in sweat, making it hard to see. Overall, very good product.

Bought this mainly to catch sweat under my helmet. Even though my helmet is snug, it still fits with this on. It breathes really well and stretches well, so don't worry about the fit. I will buy a few more; they were a good buy for the price.

I've now bought two sets of these and like the fit and ventilation they provide. As a cyclist who is also bald, I find these to be great on the bike under my helmet to keep me cool while preventing my head from getting weird tan lines. The reason I dropped the stars down is that the orange color is awful. It's more of a watered down peach color rather than orange. I expected a different color than what I got and would not have bought it has I known this was the color.

I got these for under my bike helmet. I’m bald and the sweat drips in my glasses. This completely stops that! No more drips causing me to not see where I’m headed on my way done the mountain. Very comfortable. I even have a large head and they are not too tight.

Works amazing for under my hardhat at work to keep my hair from getting the marks from the cross bands

I bought this to put on my head at night so that I wouldn’t get “CPap Hair” any longer. It works fine, but it is a little small for my 7 3/4 head. Pops off a bit frequently. If it were a little larger or my head was smaller, it would be 5 stars.
