USMC SAND FROG SW UNDERSHIRT USED

Genuine USMC-issue Flame-Resistant Silkweight (FR SW) Undershirt in sand tan — a proven piece of the Marine Corps combat wardrobe, originally issued to Marines operating in high-heat and fire-risk environments. This is the real deal from U.S. military supply channels, not a copy, offering your customers authentic Marine Corps kit at a price point that reproductions simply can't match on story or provenance.

Built for Heat, Fire, and Field Abuse

The FR Silkweight undershirt was developed as the Marine's next-to-skin base layer under body armor and combat blouses. The lightweight flame-resistant knit is engineered to resist ignition and melting — a critical safety feature that separates military-issue base layers from ordinary cotton or synthetic tees. The sand colorway coordinates with MARPAT desert and coyote/tan uniform components, keeping the wearer visually squared away with the rest of their kit.

Key Features

• Genuine USMC issue — authentic Marine Corps supply, complete with issue tag/label at the hem

• Sand tan colorway pairs with MARPAT desert, coyote, and FDE gear

Who It Sells To

This is a strong add for shops serving veterans and active-duty personnel replacing worn kit, airsoft and milsim players building authentic USMC loadouts, hunters and outdoorsmen who want a proven base layer for warm-weather field days, and preppers and collectors stocking genuine Marine Corps gear. The FR rating also makes it appealing to shooters, welders, and anyone working around ignition sources.

Condition

Used, previously issued. Expect honest wear consistent with service use — light fading, minor wash character, and the lived-in feel that only real-deal surplus carries. Inspected and graded for continued wear.
