Bememo 20 Pieces Hat Size Reducer Foam Reducing Tape for Hats Caps Sweatband

These were the best quality of four different brands I have purchased. They are thick and the tape does stick well. They are comfortable. I bought a hat that was two sizes too large as it was the only one left and I removed the sweatband and these attached perfectly to the hat.

I like these better then the others I've used. The adhesive is not so tenacious that you can't reposition it a little as you're getting it positioned under your hat band but still sticky enough to stay put once you get it situated where you want it. This appears to be a very durable, closed cell type foam so it doesn't eventually squish down to a useless thickness after you've worn it a while. The stuff is easily cut to whatever length you need with scissors and I normally cut them in half lengthwise as I find that width to be more than necessary for the task. This one package should be a lifetime supply for me and in fact I suspect I'll end up using some of it for other purposes.

They work nice but could hav3 a bit more adheasive

Smaller, individual strips allow for more accurate sizing. Good adhesion.

Using in all my hats.
