Whether you’re working in a refinery, workshop, or on a remote mine site, this flame-retardant overall’s got you covered from top to toe.

Crafted from 311gsm premium cotton drill, this fabric is as tough as they come while staying breathable enough for all-day wear. The weighty cotton provides excellent durability and resistance to wear and tear, making it perfect for heavy-duty industries. Despite its rugged build, it’s soft against the skin and allows good airflow — a must-have when you’re working in the Aussie heat. The material has been specially treated to deliver flame retardant (FR) protection, offering dependable defence against heat and fire hazards.

The DNC 3421 isn’t just any regular coverall — it’s made to comply with international F/R standards. It meets the BS EN ISO 11612:2008 standard for protective clothing designed to safeguard against heat and flame (Clause 6.3). It also achieves a Hazard Risk Category 2 (HRC2) rating and an Arc Thermal Performance Value (ATPV) of 14 cal/cm², as per the ASTM F1959/F1959M-12 standard. What that means is simple — this overall can handle serious heat exposure and arc flash hazards, offering a strong layer of defence when working near electrical energy or open flames.

To top it off, it’s certified with the Oeko-Tex® Standard 100, ensuring it’s safe to wear directly against the skin. This is a big win for comfort and peace of mind — no harsh chemicals, no irritants, and no dodgy coatings that fade away after a few washes. Plus, it’s rated for 50+ domestic washes at 60°C, meaning it’ll hold up wash after wash without losing its fire-retardant properties or comfort.

Functionality is key with any good workwear, and the DNC 3421 nails it. It comes with a large tool pocket on the lower leg, perfect for holding essentials like measuring tapes, pencils, or screwdrivers. There’s plenty of room to keep your gear close without slowing you down. The press stud closures make it easy to get in and out of, while also ensuring a secure fit once you’re zipped up and ready to go. The gusseted sleeves provide freedom of movement, giving you flexibility when stretching, lifting, or reaching — because no one likes feeling restricted mid-job.

The classic navy colour keeps things professional and clean-looking, even after a tough day on the tools. It also hides dirt and grease well, so you’ll look sharp even when the work gets messy. Available in a wide size range from 77R–112R and 92S–132S, it caters to just about every tradie’s body shape, ensuring a comfortable, practical fit for both regular and shorter builds.

Another standout feature is the comfort fit design — roomy enough to wear over other layers but not so baggy that it catches or gets in the way. The attention to detail, like reinforced stitching in high-stress areas, ensures this overall can take the knocks and scrapes of daily site life.
