These strips are the best since they are lightweight and thin.
I had several terrycloth strips from another company which, were not only difficult to work with since they were so bulky but felt awkward when wearing my hat.
I bought these for my second purchase, since the first hat ran too large (XL). L is fine a little loose, but perfect with these strips.
So I seem to have a head that is too small for "small" and too big for "med".
The strips work great for making sure the hat fits secure & does not get blown off. One thing, the white tape was a challenge to remove before applying to the inside of the hat, but my husband finally got it off and all was good to go!
Helped a lot.
I purchased the strips only because I was not sure that the hat would fit correctly. Frankly, these strips should be provided at no cost to ensure customer satisfaction of the hat. They are overpriced at $5 considering they also were made in China.... Not Impressed.
I recommend getting the adhesive size reducing strips to make the fit perfect.
