MEN'S FLAME RESISTANT BASE LAYER SHIRTS

Stay protected and comfortable with durable arc-rated and flame resistant (AR/FR) base layer shirts designed for electrical workers, oil and gas professionals, and industrial crews facing arc flash and/or flash fire hazards. Our men's FR base layers combine protection with moisture-wicking, lightweight performance fabrics that work as your foundation layer in any season.

Whether you need a standalone FR shirt for warm weather work or a thermal base layer for cold weather protection, Tyndale's flame resistant base layer collection delivers compliance and all-day comfort. Each fire retardant base layer shirt maintains its protective properties wash after wash, providing reliable flame resistant protection for the useful life of the garment.

WHY FR BASE LAYERS MATTER

Flame resistant base layers serve as your defense in electrical and industrial work environments. These versatile shirts:

• Provide critical protection closest to your skin where it matters most
• Function as standalone lightweight FR shirt or as part of a multi-layer FR system
• Wick moisture away in hot conditions while retaining warmth in cold weather
• Meet applicable requirements for ASTM F1930, ASTM F1506, ASTM D6413, and/or NFPA 2112

SAFETY STANDARDS & COMPLIANCE

Our men's flame resistant base layers meet rigorous industry safety standards including ASTM F1930, ASTM F1506, ASTM D6413, and/or NFPA 2112, depending on the garment. These standards ensure your FR base layer shirts provide proven protection against arc flash and/or flash fire hazards, helping you maintain workplace compliance and personal safety on every shift.

PREMIUM PERFORMANCE FABRICS

Crafted from advanced moisture-wicking materials, our FR base layers deliver breathable comfort without compromising protection. Lightweight knits and performance fabrics move with you while regulating temperature—keeping you cool when it's hot and providing an insulating layer when temperatures drop.
