Not the best but it will do.

It works to some degree. If you sweat a lot like me then it might not be enough for you. I got the black one but found that the color runs a bit and left a little black coloring where it was. Also it's sticky in that spot as well when you remove them. However, if you only use hats casually or don't sweat a lot then it'll probably be good for you but I'd get the white one if you wear lighter colored hats.

Very good product. Prevents sweat stains in hats as promised.

These left the adhesive on my hats. Now I have to deal with removing adhesive. Won't buy again.

This is a really good product. I did attempt to use it more than one use and the sweat did go through it so like they recommend, it’s a one time use and take it off and replace it with another. I did leave it on a couple days and the adhesive starts to stick to the hat so when you do takeoff the band, the adhesive stays behind so if you follow the directions and use these at one time use and dispose of it generally probably won’t run into the same problems as I did, but definitely as advertised and you got a good amount of them for your money, so just switch it out and save yourself the trouble

These are somewhat difficult to get to stick to your hat..but if you leave it on it becomes impossible to remove all of the adhesive from the hat.It does block sweat well and doesn’t try to fall out but can easily ruin a hat if you don’t remove it after each use

My husband sweats so so much and these absorb all of it. It’s definitely worth the money and he doesn’t have to buy a hat every other month now. Great quality. You can’t even tell that they are in the hat. Sometimes he does double up just to have some extra barriers but they work so well
