Custom made welding caps
I like to throw these things out when I see them. QuiltingB has a cool website with custom fitted skullcaps for welders. These welding caps are 100% pre-shrunk cotton & have a print fabric on the outside and are lined with a matching solid color cotton fabric.
The site says, "My caps are custom made to your head size. For your convenience." They offer a sizing chart.
Thinking of picking one up!
