When you’re enjoying the great outdoors, it's always smart to wear a hat to help keep the sun out of your eyes and avoid getting those nasty scalp burns. But heat leads to sweat—a lot of it. The problem is that washing machines aren't necessarily kind to hats, and each new cycle brings your cap closer to ruin. You can help avoid this with these disposable liners that absorb forehead sweat before they wreak havoc on your favorite hat.

All you have to do is peel off the adhesive from one of the disposable, sweat-absorbing NoSweat liners and stick it onto the inside of any hat. Then, when you’re done wearing the hat for the day, you can remove the liner and throw it away. Not only will the liner keep your caps clean, but they're also breathable and hypoallergenic to help prevent forehead acne and redness from occurring. In addition, since the hat liner wicks away sweat and heat, you’ll no longer have to worry about your glasses fogging up in the middle of your favorite outdoor activities.

NoSweat hat liners come in packs of three, six, 12, and 25, so you can keep some in your car and stock up for vacations. Right now, the company is also running a promotion on Amazon. If you buy two hat liner packs, you’ll get 20 percent off; buy three, get 25 percent off; buy four, get 30 percent off.
