USMC FROG Flame-Resistant Thermal Base Layer Shirt — Olive Drab

USMC FROG Flame-Resistant Thermal Base Layer Shirt — Olive Drab

SURPLUS, SOLD PER EACH

The USMC FROG (Flame Resistant Organizational Gear) Thermal Shirt is a core component of the Marine Corps’ elite cold-weather layering system, engineered to keep warfighters warm, dry, and protected during demanding operations. Built from advanced flame-resistant performance fibers, this shirt delivers exceptional thermal insulation without sacrificing breathability—exactly what Marines rely on during long training cycles, field deployments, and harsh winter climates. Lightweight yet impressively warm, the FROG thermal top wicks moisture away from the skin, dries rapidly in the field, and layers seamlessly beneath uniforms, plate carriers, and outer shells. Its olive drab color and reinforced seams echo the durability and purpose-driven design that define modern USMC gear. Whether you're building out your winter kit, prepping for outdoor adventures, or simply want professional-grade thermal wear, this authentic FROG shirt brings battle-proven performance to everyday life. Every unit may show minor handling or storage marks consistent with genuine military surplus.
