Authentic USMC FROG Mid-Weight Thermal Base Layer
This is genuine USMC-issue FROG (Flame Resistant Organizational Gear) Waffle Mid Weight Thermal Bottom—the exact base layer trusted by U.S. Marines in extreme operational environments. Engineered to deliver critical thermal protection and flame resistance when conditions demand peak performance.
Mid-Weight Waffle Construction
The signature waffle-knit pattern creates insulating air pockets that trap warmth while maintaining breathability and moisture management. This mid-weight construction strikes the optimal balance between thermal protection and mobility—warm enough for cold-weather operations, yet breathable enough to prevent overheating during high-output activity. The grid pattern also accelerates moisture wicking, keeping you dry when you're working hard.
Military-Grade Flame Protection
Every FROG garment meets stringent military flame-resistant standards, providing critical protection in high-risk environments. The FR treatment is integrated into the fabric itself—not a coating that washes out—ensuring consistent protection throughout the garment's service life. This is the same level of protection that Marines depend on in combat zones and hazardous duty assignments.
Technical Features:
- Flame-Resistant Fabric: Meets military FR specifications for reliable protection in fire-risk environments
- Waffle-Knit Construction: Creates thermal air pockets for superior warmth-to-weight ratio
- Advanced Moisture Management: Wicks perspiration away from skin to maintain thermal regulation
- Flatlock Seams: Low-profile construction eliminates chafing and pressure points during extended wear
- Mid-Weight Design: Versatile thermal protection for variable conditions and layering systems
