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 got this to keep the sweat out of my face when i worked construction. It didn’t quite do the trick, but it kept my head breathe-able and it was super comfy.

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

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.

Product is well-sewn and fits the head comfortably. However, I wanted it as a night time head covering to prevent the straps of my CPAP machine from forming permanent creases in my hair. Because it is constructed of thin silk-like material, the skull cap slips awry during the night and doesn't serve my purpose.
