Magpulunisex-adult Magpul Trucker Hat Snap Back Baseball Cap, One Size Fits Most Baseball Cap (pack of 1)

Is the hat itself made in the USA?

What is the maximum hat size that the XXL will fit?

How do I know what size to use there is no size chart?

Is someone mass buying the camo version? It sucks for someone who just wants 1. Every time they come in stock, they sell out within minutes.
