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

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

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!

This product gets poor reviews from some however I believe its because most people don't apply it correctly. I didn't either until I discovered the right method for myself. Used this on a 6x Stetson that was getting a little floppy. The first two applications, I just sprayed it on and let it dry. Results were disappointing. What I discovered is that you need to spray the surface liberally and then RUB THE SPRAY INTO THE FELT gently with your fingers. Let dry. Your hat WILL be stiffer! You may apply this way twice or more to get desired stiffness. You may also want to use a glove as it will transfer the die to your fingers if you don't. After I used this method, my Hat is like brand new and holdin its shape just like I wanted. The manufacturer really needs to include this information in the use instructions!

Sprays on easy dries fast no strong odor ! Works Great!!

My Stetson Temple was all fluffy and uncomfortable; I had to keep fixing the brim at all times. I was tired of the flying fluffy brim. I applied the Khal stiffener a couple of times, using a teapot to steam after the sittener dried for a couple of hours. After the teapot steaming, I could feel some residue in the fur felt. I reasoned that the starch did not have enough time to diffuse inside the felt. I tried then another approach to steaming. You can see my approach in the picture. I used a humidifier, with a trash basket on top, and the hat on top of the basket. I left the hat there for several hours, removing the condensed water with a towel from time to time. After the process, presumably all of the Khal Stiffener was absorbed by the felt. I could not feel any residue anymore. I brushed the hat when dry, and the texture was not affected. The brim took a nice shape, just a little bit stiffer. The effect of the product is not dramatic. The felt acquired a nice malleable body. I decided to give the brim a snapped up shape everywhere but at the front of the hat. The brim shape has prevailed after a couple of wears.This Khal Stiffener product solved my problem. I did not have to do a professional hat restoration.I must admit that part of the success was the slow steaming process. I applied the same humidifier steaming, over several hours on another Stetson Temple, without using the Khal Stiffener product. That second hat looks again like new.Overall, I am happy with the outcome. The brim now has a steady shape (I cannot play with brim positions anymore, but I prefer such). If you use this product, make sure you give enough steaming time for the starch to diffuse into the fabric. I am guessing that people complaining about white spots is due to starch buildup after several applications. Again, starch buildup does not occur when steam acts on the hat for a long time. Hats need some steaming from time to time to help them keep shape, just like shirts need ironing.

It was not effective stiffening a cheep hat

This is an incredible product, as long as you use it on a quality hat. My 10x Americans feel like they're made out of cardboard now, and my 100x Amercans feel like they're carved from would. I did three applications, with drying between, on the outside and inside of each hat, then steamed them, and they are all more rigid than they were the day I got them.

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