USGI Improved Hot Weather Patrol Cap (IHWCU)
$39.99 USD
US Genuine Hot Weather Patrol Cap (IHWCU), in new and unissued condition (sometimes in original sealed packaging). Part of the official U.S. Army Improved Hot Weather Combat Uniform (IHWCU) series, designed for hot and humid environments with mean monthly temperatures exceeding 68°F (20°C).
It features six metal eyelet vents for maximum airflow, a lightweight 50/50 nylon-cotton (NYCO) ripstop fabric that enhances breathability while remaining durable and tear-resistant. The design prioritizes heat dissipation and ventilation, making it ideal for tropical, desert, and high-heat field use.
This version has no ear flaps, distinguishing it from the standard temperate patrol cap.
