Kahl Hat Stiffener - Great for Fabric & Felt Hat Brims - Will Not Affect Tone, Texture, or Color

This is a very good product that I've used successfully on both felt and straw fedoras. It's safe for my expensive hats, and hasn't left any visible buildup or discoloration on any of them. Just spray it on evenly where you want to stiffen, shape while it's wet, and let dry. That's it. A little steam afterward allows you to finish shaping. Easy. You may need to repeat the process a time or two with some hats, but I generally get the results I'm looking for with one application.

Makes cheap floppy hat look up market. Brim is stiff now. But, I applied about 10 coatings.

it works good just took a little bit to get it

Very happy with this product. Stiffness and holds. Able to shape my hats like a pro now. Highly recommend.

I used it on a hat tonight and it came out good in fact better than good it worked great 👍

This is an expensive product for the amount required to stiffen a hat brim. I am going to look for other products that might do a better job with less.

Whether you are just taking care of your existing fedora family, or reconfiguring a feral find from the local thrift. Excellent product, I’ll be getting more!
