Hat Reducing Tape for Indiana Jones Hat

Yes, it looks like window/door insulation tape, and probably is one of those obscure sizes that you can't find at Home Depot, but it does work. I'm not sure if it reduces the hat size by 1, but I can tell you that to get that prefect and comfortable fit you have to test fit (without removing the adhesive backing) along the inside of the sweat band. Sometimes you might have to cut the tape down to get it that sweet spot. At least he price is somewhat reasonable at a $1, but it would be more realistic to be about 70 cents or less. Anyway at these prices who it doesn't really make that much of a difference.
