These genuine USMC FROG Silkweight Thermal Drawers are part of the Marine Corps’ Flame Resistant Organizational Gear system, built for next-to-skin comfort in demanding conditions. The silkweight fabric is designed to be lightweight, breathable, and highly moisture-wicking, helping regulate body temperature during movement while preventing sweat from building up under uniforms or outer layers.
 
The flame-resistant fiber blend provides reliable protection against flash heat and ignition sources, making them a safer alternative to standard thermals in both military and industrial environments. Despite their light feel, they perform exceptionally well as a base layer in cold weather, drying fast and resisting odor buildup during extended wear.
 
This pair is new and still sealed, making it ideal for customers who prefer unused military gear or want the highest-quality base layer straight from original contract packaging.
