MELASACooling Skull Caps Helmet Liner, Lightweight Mesh Under Helmet Cycling Motorcycle Hard Hat Sweat Liner for Men Women

Best quality cap you'll ever buy. It absorbs all the sweat and is the most comfortable to wear...

I use this in the pool. It does do a good job cooling as long as the water is cool when it’s Not on my head, I rub it around my watch so my Crystal doesn’t get hot so it’s definitely nice to have and well-made

So far this has done what’s expected of the cap. I’m a sweater and it certainly absorbs a lot of it and helps keep the sweat off my face while wearing my helmet. My only complaint is that it’s a little loose. I mean it’s not made for someone with a smaller head. I wear a hat size of 7 & 5/8, or 55cm and it won’t stay put when I remove my helmet. Not a deal breaker, just wish it could be a tad bit tighter. It’s light weight and provides a nice comfort barrier between my helmet and my hair. No more pulling as I put my helmet on and off. I can’t speak on longevity as I just started using it, but the build quality seems good. With nice and tight stitching along the seams. All in all a good enough product for what I wanted it for, and I would say get one if you just want something to soak up some sweat and help protect your head from severe helmet hair. But beware, it’s not made for anyone with a smaller head.

I only want to help fellow big-headed humans and report that two different ones of these fit my xxl head perfectly, quality is good as well.

It looks small but it fits and it stays. it does work and it won't fall off. before using it I sweat under my helmet but this kept me cool.

I like the lightweight, coolness of this cap but the sweat just pours from it onto my face. I think it needs a liner, strip of some sort to stop the facial dripping. Fits well under cycling helmet, feels good, just not wicking enough for me. Recommend if just looking for a liner. I think it will be decent for cooler weather.

Light weight, fits well, wears well and breathable. Love it ordered two more!

Comfortable, collects sweat, and easy to use! Should be a breeze to wash also. Great stuff!
