NoSweat Product Review Reviews by Russ_Cohen - September 28, 20180 Share on Facebook Share Share on TwitterTweet Share on Pinterest Share Share on LinkedIn Share Send email Mail Print Print With the rising cost of hats, and the problem that sweating in them causes, enter NoSweat a company who has made disposable hat liners. Do they work? Read on. I wore one in a favorite hat of mine for over a week and it did the job and then some. I wore it to a football game in 80-degree heat and no way to get out of the sun. It reduced the amount of sweat dramatically. When I got home I didn’t have to hang up my hat to dry. Even though these are disposable you can wear them for a few times with no issues. The glue sticks very easily and it stays. My hat didn’t show any staining and in cooler temps kept my head a bit warmer then it would have without it. For less than $20 for a 12-pack, you can place them in all of your hats and you don’t have to worry about how you’ll need to clean them in the future. I have an expensive replica 1962 Mets hat, one a few were made, I almost never wear it because of the issue of sweating in it. Now I will wear it with confidence. They have different colors as well to match your hat, helmet, etc. See more at www.nosweatco.com
