A custom fitted is a cap that is specially made and can't be bought everyplace. There are a few stores and websites that let you pick the cap style, logo and all the colors. You can pretty much create the capsof your dreams.
There are also custom caps that people collect. You can collect caps of your favorite sports teams or from places you have visited. These types of caps are great conversation starters and can bring back memories of when you got them.
Collecting caps can get expensive. Prices can range from 10 - 15 dollars up to 40 dollars. But depending on your reason for buying custom caps the price is worth it.
