Our Snapback Replacement Hat Strap are engineered 100% compatible to the current Snapback Replacement Hat Strap. It is constructed of the same material, same length, and same attitude that is meant to endure even the most unimaginable punishment. Lastly, the design was made possible thanks to the inspiration of Leonardo Da Vinci's The Vitruvian Man, a body of work that emphasized directly on Curved vs. Straight lines: Circles vs Triangles, a principle of duality that pervades all of the Universe.
