Hat size reducer tape is a great way to size down your hat! Did you buy something that is just a little bit too big? Fear not, this light one-sided sticky foam filler can be used to reduce the size of a hat by almost a complete size, and more if you double-up. We commonly use this product in our stores when a hat someone would like is just a tad on the large size. The beauty of this, is that because it fits underneath the hat band, the hat does not look too big when applied as there are no gaps between it and your head.
