20PCS Hat Sweat Liner, Hat Shaper Insert for Men, Black & White

Excellent quality. Fits my ball caps perfectly. 2 colors, white and black!

Perfect for hanging our hats and they stay in place and don’t fall out.

Their okay. Nothing special .

These are garbage. This is the only one of these hat liners on Amazon that doesn’t have adhesive on the back so it doesn’t stick. Its just supposed to sit inside the hat and not fall out?It’s also not thick enough and sweat bleeds right through it. Garbage!!

There was smooth putting them in, they fitted nicely and they got the black ones and the white ones you can't tell if you got it on.I love these cause.I'm a love baseball hats

These work. Had a little trouble getting it in there, maybe because my hat is a bit smaller, but once in, seems to work well.

Work surprisingly well. I don't worry about sweat bands on my hats because I know I'm going to end up with them anyway. But does a really great job in keeping the sweat out of my eyes.

These hat liners work great! I have used various hat liners over time and these work as well as any that I have ever used. The nice thing about them is that they are sturdy so they help reinforce the shape of the hat even for those hats that are without inherent shape (floppy hats!). For older hats I found that they give back some of the original shape to make it look more attractive and newer. Some may feel the stiffness is a drawback but I found that stiffer hat liners tend to stay in place better so to me that was a plus. It is easy to place and works well for absorbing moisture and sweat to keep the sweat stains away. The material is sturdy yet soft enough to be comfortable. I like that you can trim them to fit and customize it for different sized and types of hats. You get 20 in the pack so it is a good value and worth buying if you are looking for something to keep sweat stains away from your caps or even just a liner for more comfort or to reshape an older cap.
