US Military DriFire Short Sleeve Shirt

Flame-Resistant Base Layer

The DriFire short sleeve shirt is a US Army-issue base layer built for high-heat and flash-fire environments, where an ordinary synthetic tee can melt onto skin. It is cut to be worn under a flight suit or on its own, and the light knit wicks sweat and dries fast through long days in hot conditions. Aircrew, vehicle crews, range shooters and collectors of issued kit all have a reason to own one.

Features

• Inherently Flame-Resistant Fibers — The flame resistance is part of the fiber itself rather than a surface treatment, and the fabric will not melt or drip when exposed to heat or flash fire.
• 4.5 oz Silkweight Knit — Silkweight means a thin, fine knit that sits smoothly against the skin, and at 4.5 oz this is an ultra-lightweight fabric.
• Moisture-Wicking Construction — The knit draws sweat off the skin and out to the surface of the fabric, where it can evaporate and let the shirt dry quickly.
• Odor-Resistant Fabric — The fabric resists odor buildup, which matters when the same shirt stays on through extended field use.
• Flatlock Seams — The seams are stitched flat instead of folded into a raised ridge, so there is less to rub and chafe under straps and outer layers.
• Dropped Fit With Athletic Cut — The athletic cut keeps the shirt trim enough to layer under a flight suit without bunching.
• Crew Neck And Short Sleeves — A plain round collar and short sleeves with stitched cuffs give a clean T-shirt profile that works alone or under a uniform.
• Genuine US Army Issue — This is an originally issued military base layer, not a commercial lookalike.

Issued Army Specification

The DriFire shirt was issued to US Army personnel as a flame-resistant base layer, intended for use under flight suits and as a standalone garment in high-heat roles. It was made in Coyote Brown and Desert Sand, the tan shades that match current Army uniforms and gear. Owning the issued version means you get the fabric and FR protection the Army specified, along with genuine provenance for a collection or a period-correct kit.
