DNC 3411 Patron Saint Flame Retardant Drill Pants

DNC 3411 Patron Saint Flame Retardant Drill Pants

When it comes to flame-retardant work pants that stand up to the heat of the job, the DNC 3411 Patron Saint Flame Retardant Drill Pants set the benchmark for safety, comfort, and durability. Designed for Aussie tradies, sparkies, and industrial crews working in high-risk environments, these FR drill work pants are built to perform. Whether you’re tackling welding jobs, working with live electrical gear, or on a mining site, these pants keep you safe and comfortable all day long.

Built Tough from Premium Cotton Drill

Made from 311gsm heavyweight cotton drill, these flame-resistant pants are built for the long haul. The tough, natural fibres offer exceptional durability and breathability, making them ideal for the Australian climate. You’ll get that strong, reliable feel you expect from drill fabric while staying cool and comfortable even on the hottest days.

Unlike synthetics that melt when exposed to heat, these 100% cotton FR pants give you safe, dependable performance around sparks, open flames, or high-temperature work areas. They’re perfect for electricians, welders, engineers, mechanics, and anyone who needs fire-resistant workwear that’s tough enough to take on the day-to-day grind.

Serious Flame-Retardant Protection

The DNC 3411 pants comply with international flame-retardant standards, including BS EN ISO 11612:2008 for protection against heat and flame. They also meet the ASTM F1959/F1959M-12 arc-flash standard, with an impressive ARC Thermal Protection Value (ATPV) of 14 cal/cm² and a Hazard Risk Category (HRC) 2 rating.

That means these FR drill work pants are tough enough to handle arc flash exposure and heat hazards, reducing burn injury risks and keeping you safe when things get unpredictable. Whether you’re working on high-voltage systems or near open flames, you can trust the Patron Saint range to keep you protected.

Smart Tradie Design

These flame-retardant pants don’t just protect — they’re built for comfort and practicality too. The pleat-front design gives you plenty of room to move freely on the job, whether you’re bending, climbing, or lifting. The heavy-duty nylon zipper provides long-lasting reliability, designed to handle the tough conditions of an Aussie worksite.

You’ll find the fit relaxed yet professional, making them a great choice for both on-site work and workshop environments. Available in a wide size range — 77R to 107R, 87S to 132S, and 74L to 94L — every tradie can find their perfect fit.

Skin-Safe and Long-Lasting

The DNC 3411 FR pants also meet the Oeko-Tex 100 certification, meaning they’re completely safe to wear against your skin. No harmful dyes or chemicals, just comfortable, breathable cotton that feels right for long days on site.

These pants are built to last through 50+ domestic washes at 60°C without losing their flame-retardant properties. That means your FR protection stays effective wear after wear, giving you peace of mind and great value for money.

Classic Look, Built for Work

Finished in professional navy, these pants are all about function with a clean, smart appearance. The colour hides dirt, oil, and dust — perfect for tough work conditions. Pair them with an FR-rated hi-vis shirt or jacket for a fully compliant arc-flash workwear set that keeps you protected from head to toe.
