Works as advertised
It does exactly what it says -- using one of these made my slightly-too-big hat fit well. I haven't tried removing and reapplying the sizer yet so I can't vouch for whether it survives multiple applications.

Great Value and Quality Hat Sizers
I used this in one of my hats that is just a little too large. These are high quality and work perfectly. I highly recommend them.

Sun Hats that fit well
I just bought the T5MO Adventure Airflo Hat and the LTM5 Airflo Sun Hat and like both of them very much. So much so that I have ordered their All-weather Brim Hat. They are comfortable to wear (the spacers really help). I've worn them in very sunny humid weather and they never got annoying. They look good too.
