Sized caps (not one-size fits all)

[twinsmom2]

I am looking for caps that come in sizes e.g Small, medium, large - as opposed to One size fits all. Most interested in low profile, unstructured, velcro closure.

You will want to look into flex fits
They come sized S/M L/XL
Most all sellers have them
Ottos Caps maybe.
Sized hats will have no closure
