The interlock embroidery on this cap is styled with an old school flare. "GSU" stands for Grindstone Universal and this black and red color combo works well. With a hint of gold embroidery on the outline, it looks regal.

We sourced the finest wool available – 100% Merino Worsted Wool. This wool was destined to become a ball cap. Made in a US factory (New York City) that placed a premium on design and craftsmanship.
