Another product we use in-house, Kahl's Hat Stiffener is specially formulated to protect the shape of material through heavy wear. It will bring the life back to softer hats and this product's gentle stiffening action allows you to dial in your preferred level of material retention with the number of applications. It will not turn yellow or flake off and will not affect future hat cleanings, shaping or reblocking. 8 oz spray bottle.
Made in USA.
