Perspiration can lead to short- and long-term stains on hats - and it's uncomfortable! These Disposable Hat Liners protect you and make you feel dry, comfortable and confident all day.Simply peel and stick the pad on the inside of your hat and you're ready for a sweat-proof day! The liner is made of a highly absorbent material that collects moisture and stores it. The Pad is designed to wick and store quite a bit of perspiration, but if you tend to sweat excessively, especially in the summer months (it's common), you may consider switching out the sweat pad in the middle of the day. Just toss the old one and apply a fresh one.
