What constitutes a giant head?

I consider a giant head to be anything north of a 7 5/8" hat size. Alot of cap manufacturers today use the "One Size fits (Sm)all" model which has been the scourge of large headed people for decades. Thankfully we've been able to source some larger caps to accomodate the big brain folks. If you're under 7 1/2" hat size , everything on the website will fit. If you're over 7 1/2" , look for ones that are giant head compatible for a comfortable fit.

To figur out your hat size, measure the distance around your head and check it against the chart below.
