Shapers Image 3 pcs Baseball Crown Shaper Inserts for Low Profile Fitted & Snapback Caps, Washable Reusable Sports Hat Liner

Works great

I have a few of these soft, washed cotton caps that needed extra structure. These are easy to place and have the additional benefit of keeping sweat from forehead away from material which is great for special hats. The hat sits comfortably with inserts in while wearing and makes your hat look less wrinkled. They sit securely behind the brim without adhesive and can therefore be swapped to other hats as necessary. This is a level up from diy solutions and are durable and will last many years. Good value.

They are visible due to being a bit too thick. They leave an impression that is noticeable.

Holds the shape of my caps perfectly. Great value for the money!! No doubt it will keep my caps in shape for years to come.

It seems to do what is supposed to do, but the only problem I have is that it makes my forehead feels so hot and make me sweat a lot and it doesn't absorb the sweat either, so it's a no for me.

Made the brim better

W.ork well, may need a dab of super glue or rubber cement to keep securely inlace

Some times unstructured "dad" hats are a little too unstructured. These inserts work great. The end wings stick out a tad but not noticeably. They may conform better as you wear it more and more. Some reviews mention a need for adhesive but if you follow the instructions, they just slip into the folded lining inside the hat and stay put (unless you're a break dancer). The insert may help a hat fit better as it adds 2-3 mm (I think) but definitely added better structure to my embroidered hats and made logos and text legible. Nice product
