Size Reducer Strips

Did you know Ultrafino was the first to invent the hat size reducer? Years later we've perfected our design to offer the best solution for a slightly loose hat.

Have you ever purchased a beaver, wool, felt, straw, Panama hat or a Montecristi hat, but it turns out to be a bit too large? Now you can use these foam size reducer strips to get the perfect fit and eliminate a loose fit!

The two 8-inch strips are self-adhesive on one side and made with 1/8"-thick sweat-resistant foam. The rounded edges make it extremely easy to peel back and place underneath the sweatband.

With the use of both strips, these can reduce up to a full hat size without the hassle of returning the hat. Used by Professional Hatters. Made in the USA.

Perfectly did the trick!

It took quite a long time to arrive once ordered due to the method of delivery to Canada, but once received it was fantastic. A hat too large was resolved with just one insert. My husband is now very happy with his new winter crossover hat.

For those in-between sizes

Ordered these to fit one of my hats because I was in between two sizes. I put one on the back side to decrease the size and it worked out just great.

A perfect fit.

If your hat is a bit too big for you, the Original Hat Size Reducer is the easy way to get a perfect fit.

Hat Sizer Reducer works great!

If your hat is a tad to too big, these reducers are great to make the fit perfect. I bought a couple of them with the new hat from Ultrafino, knowing I had other hats already that did not fit properly and would reccomend them to anyone!

Topped Up

My newly arrived Packable Panama Fedora was “perfect,” except at 7 5/8 it was just a bit too lose. A moderate breeze was always a threat to unhat me. Previous 7 3/8 hats had been just the opposite, too tight by a smidge. (Evidently my skull is a misfit.) The solution to this awkward situation was simple. A couple of strategically hat size reducer strips offered by Utrafino completed the perfect fit. Now gentle summer breezes are always welcome, as they should be, and my wardrobe remains topped up easily!
