USMC Tan FROG Silkweight Base Layer Top (Size S-XL) - New or Used

USMC FROG Silkweight Base Layer Top – Tan

The USMC Flame Resistant Organizational Gear (FROG) Silkweight Top is the ultimate foundational layer for the modern Marine. Developed to provide maximum protection in high-heat and flash-fire environments, this shirt is a core component of the FROG system. Unlike standard polyester base layers, the FROG silkweight fabric is Inherent Flame Resistant (IFR)—meaning the protection is built into the fibers and will never wash out or wear away over time.

Utilizing Polartec® Power Dry® FR technology, this top is engineered with a specialized "silkweight" knit that excels at moisture management. It pulls sweat away from the skin and disperses it across the fabric's surface for rapid evaporation, keeping the wearer cool in the heat and dry in the cold. In New (unissued) or Used condition, these shirts provide the factory-fresh elasticity and antimicrobial performance required for long-duration field missions.
