Sweat Defend Hat Liner for no Sweat Stains for lids Hats. Best! hat Protector hat Saver hat Sweat Band, Sweat hat Liner

These are great! I have several white cotton twill visors that get dirty where they rest on my forehead, even when I don't wear makeup. There is colored embroidery on the front of the visors so I can't bleach them (carefully tried that once -- bad idea) and the stains won't fully come out even with a tedious scrubbing. This liner solves the problem beautifully! I just swap out the liner as needed. I wear it several times before tossing it. The liner basically looks and performs like a long, skinny pantiliner. It's thinner though and I do not notice it all during wear.

First the positives. The length of the liner fits around the rim of the hat well, the adhesive is good, and the price is good compared to other brands. That being said, it is far too thin to do a good job of absorbing sweat well. I sweat a lot, and within a half hour I had the liner completely soaked and hat to put in another. Therefore, it could stand to be a bit thicker, but not too much that it affects the fit of the hat. It could also sit taller in the hat so it covers the rim of the hat in addition to area above rim as well. I have tried a couple of other products that are more absorbent and sit taller in hat so the whole forehead gets covered and picks up more area that is sweating.

I've been looking for a simple product like this for awhile now. Living in a desert, I've ruined some of my favorite hats by sweating through them. This product is so easy and simple to use and does what it's supposed to do. The product itself is really soft and makes my hat more comfortable. Keeps it clean from being out and about all day. Once I'm done, I peel it off and slap a new one on.

I like the product because it is cost effective at the price point, I can use them as a daily disposable liner and don't mind tossing them out each day. It doesn't cover/absorb as much as I would like it too, but it works. I would give it 4 stars if the liner stayed in place better... Once saturated it moves around but at the same time it doesn't leave a residue like other ones i've tried. I'd use them again mostly on non work days.

I bought this to prevent makeup or dirt buildup on my beanie, but the liners are too sticky that I can’t remove them completely. I tried to peel a liner off my beanie but the material is too thin with a really strong adhesive that I can only peel off a tiny piece bit by bit.

Very good product. It does what its supposed to do, absorb sweat. I like it because it helps keep my forehead clear. It is a once and done product. If you don’t sweat a lot on a particular day ,it can be worn more than once. I will order this again...

I live in florida and anytime i go outside i sweat. The sweat defend was easy to apply to my hat and kept my forehead comfortable all morning while working on my shop roof. Actually made my hat feel more comfortable too.

Love these! Keeps my hats clean! No more make up or sweat on my hats!
