MOJOTORY Hat Size Reducer, Soft Latex Hat Sizing Tape, Hat Inserts to Make Fit Smaller, Multi-Sized Foam Tape for Hats and Caps, 12 Pcs

These will take those one size fits all hats and caps and make them fit great, if they are a drop too big. They have adhesive that makes them easy to use or you can just put under an inside lip, if your cap has one. Really works well and you can add them on the back, sides or wherever you need. Good price too.

Love these, added to hats that were too big and now have a great fit. Easy to attach to hats.

It works as suggested.

Easy to install, and no adhesive needed.

I needed the straps to place in my hats for church that did not have a string inside to make them tighter. The straps work. I have ordered additional ones. Thank you.

Easy to use; works well. Good length . Adhesive fails about 9 months

I was looking for something that was able to be used for padding and helping create a better seal for kn94, n95, or other disposable face masks along the nose bridge.The only ones I'd been able to find prior, were way too "open cell" type foam. Very flimsy and let way too much air flow through.These are perfect! I trim them longways so that one of these creates a nose strip for two masks. I also trim length. I use a permanent fume free craft glue to give extra staying power and let it dry overnight.These make disposable masks very comfortable for all day wear, kids approve, they don't have any strong smell because they are latex, soft, and they cause no irritation.These are the only hat strips I found that were latex. I bought another brand of hat strips made from some other much more dense foam (think flexible thick craft foam), and those are way too firm and smell unbelievably strong!These are definitely the way to go if you need to do some diy mask fitting.

I was desperate to find some way to return my favorite Panama Hat to it's "One Size Fits All" original size, you know, the one that "fit" when I bought it 2 years ago. Extra Rain and Sun caused my "One Size Fits All" favorite Panama to open another 1/2" and cause it to "droop" over my eyebrows. Then, I checked Amazon to find this great product that allows you to insert well made "fitting strips" into your hat to make it "smaller". Guess What The Dr Ordered!?
