Our navy blue cotton ball cap has a sewn-on patch of the Lost Art Press seal, which features dividers (a symbol of woodworkers everywhere).
A small family business less than a mile from our shop (the same place that prints our T-shirts) sewed on the patches for us; the work is crisp and perfect. These hats are made in China by Port & Co.; they are the best cotton "dad hat" we could find before getting into crazy pricing.
One size fits all. The hat has a fabric adjustment strap and buckle in the back.
