Vintage USGI Olive Green 507 Hot Weather Cap (1980s) - New

The Olive Green 507 (OG-507) Hot Weather Cap is a classic piece of post-Vietnam era militaria, famously known as the Army's "baseball-style" field hat. Introduced as a component of the durable OG-507 utility uniform system, this cap transitioned the military away from the 100% cotton OG-107 fatigue covers into a much tougher 50/50 Polyester/Cotton twill blend. This upgrade allowed the hat to hold its shape, resist heavy fading, and stand up to rigorous industrial laundering while remaining lightweight and breathable in climates exceeding 68°F.

In New (Deadstock/Unissued) condition, this authentic 1980s cap is factory-fresh, crisp, and clean. Sized at 7-1/8, it features a traditional structured front crown, a rubber-interlined long sun visor, and a vintage synthetic leatherette/vinyl sweatband. It is highly sought after by historical collectors, vintage style enthusiasts, and veterans looking for an original, unworn piece of cold-war era army history.
