US OG-507 Hot Weather Cap Size 6 7/8".

The OG-507 hot weather cap represents a cornerstone of U.S. military field headgear, designed for comfort and functionality in warm climates. This size 6 7/8" example features the classic olive drab cotton construction that defined decades of service wear. The cap's wide brim provides essential sun protection while the ventilated crown allows airflow during extended outdoor operations. The adjustable rear closure accommodates individual fit preferences, making it practical for both active duty and collector display. Historically significant as standard issue across multiple service branches, the OG-507 remains highly sought by military history enthusiasts, reenactors, and uniform collectors. Its authentic construction and period-correct materials reflect genuine field-use specifications rather than modern reproductions. This example is ideal for completing vintage uniform sets, documenting military textile evolution, or adding to established militaria collections.
