USMC COYOTE FROG SW LONG JOHN USED

Genuine USMC-issue FROG (Flame Resistant Organizational Gear) Silkweight Long Johns in Coyote Brown — the base-layer bottoms that Marines actually wore under their combat uniforms in theater. These are real government-issue surplus, not a copy, complete with the orange FROG tag bearing the Eagle, Globe and Anchor. For shops serving veterans, collectors, preppers, hunters, and cold-weather layering enthusiasts, this is one of the strongest surplus base layers you can put on the shelf.

The FROG silkweight program was developed to give Marines a flame-resistant next-to-skin layer that stayed comfortable under body armor and utilities. The knit is smooth, lightweight, and stretchy with a soft hand — it moves with the wearer, wicks moisture, and adds warmth without bulk. The signature coyote brown color matches the USMC FROG combat shirt and MARPAT uniforms, but on the retail floor it also reads as a clean, earthy neutral that appeals to buyers who want their base layer to work double duty around camp or on the trail.

Why It Sells

• Authentic issue: Real USMC FROG surplus with original branded waistband tag — instant credibility with veterans and collectors.
• Flame-resistant base layer: The FROG program's whole purpose — a next-to-skin garment engineered not to melt onto the wearer.
• Cold-weather layering: Silkweight thermal bottoms for hunting stands, ice fishing, winter chores, and shoulder-season camping.
• Everyday utility: Doubles as loungewear, sleepwear, and PT layering in coyote brown that hides dirt and wear.

Condition

These are used, previously issued garments. Expect honest field-use character — some fading, laundering softness, and light wear consistent with military service. That lived-in feel is part of the authenticity that separates genuine issue gear from anything else on the market. Recommend a wash before first wear.

Who It's For

Hunters and outdoorsmen looking for a serious cold-weather base layer, veterans and active-duty personnel replacing worn kit, reenactors and collectors building an accurate GWOT-era USMC impression, airsoft and milsim players kitting out realistic loadouts, and preppers stocking up on rugged, flame-resistant thermals.
