This is a good starter cap, or a cheap hat for a kid or anyone working on a budget. We had a few requests for something like this, so we are giving it a try. These are "one-size-fits-most". They have an elastic band hidden in the back for adjustment. Please note that these are 30% cotton, 70% polyester. Normally we don't use any polyester, but it was the only way to hit the price point we needed. These are still nice caps, and look and feel like cotton. Available in black, gray, tan, and brown.
