Vaultex NKM 240GSM 8 Cal Fire Retardant Cotton Shirt, Navy Blue

GSM stands for grams per square meter. At 240 GSM, the fabric is mid-weight—durable enough for heavy work yet breathable enough for long wear. It provides a comfortable feel without undue heat buildup, while still offering flame-retardant protection due to the Proban FR coating.

The coverall complies with multiple safety standards: HRC 2 ATPV 8 CAL, EN11611, EN11612, EN 61482, ASTM1959, ASTM1506, NFPA2112, and NFPA70E. In practical terms, this means the garment offers flame resistance suitable for electrical arcs, molten metal exposure, and general fire hazards common in industrial environments.

Key features include a flat collar, full sleeves, a metal zipper closure with a plastic button, and practical pockets: 2 front swing pockets and 2 back pockets with plastic buttons. It also has reinforced locations, heavy-duty colorfast thread, and bar-tack reinforcement at stress points for durability. The color is navy blue and the sizing is designed for men.

The garment is designed for men's sizing. To choose the right fit, consider your common clothing size and your layer needs for the job. If you’re between sizes, sizing up can give you more mobility for layers and movement on the job.

Follow the care label instructions. Generally, wash with like colors in a suitable detergent, avoid chlorine bleach, and dry per the label’s guidance. Do not use fabric softeners on FR-treated fabrics as they can affect the flame-resistant properties. Do not iron on any FR-coated areas unless the care label allows it.

It's ideal for industrial and heavy-duty tasks with fire or heat exposure risks, such as metalworking, welding, electrical work, and general maintenance in hazardous environments where flame retardancy is important.

Compared to higher-GSM or higher-heat-rated Vaultex FR options, this 240 GSM variant emphasizes a balance of light-to-moderate weight with FR protection. If you need heavier protection for higher heat, you might opt for a thicker variant. For a lighter option, you could consider similar 200–230 GSM FR cotton models. You can explore these on Fepy via the Vaultex FR category and the specific product pages: Vaultex NKM 240GSM 8 CAL FR Coverall (https://fepy.com/product/vaultex-nkm-240gsm-8-cal-fire-retardant-cotton-coverall-navy), Vaultex NKM 320GSM FR Coverall (https://fepy.com/product/vaultex-nkm-320gsm-12-cal-fire-retardant-cotton-coverall-navy).

The current listing specifies navy blue as the color. If you need other colors or variants, you can check related Vaultex FR cotton coveralls within the Vaultex brand pages on Fepy, which list available color and model variations.

Check the fabric weight (GSM), the flame-retardant treatment (Proban FR), the listed safety standards (HRC 2 ATPV 8 CAL, EN11611, EN11612, EN61482, NFPA2112, NFPA70E), and the garment construction (pockets, zippers, reinforcement). Also confirm the sizing for a comfortable fit with any added PPE you wear and the job’s movement and layering needs.

To don: step into the legs, pull up, align seams, fasten the metal zipper with the plastic button, and ensure the collar sits flat. For doffing: zip down, unfasten any pockets if needed, and carefully remove the garment. Always avoid pulling on the fabric excessively to prevent seam stress. After use, inspect for wear and wash according to care instructions to maintain FR properties.

Durability comes from reinforced locations, heavy-duty colorfast thread, and bar-tack reinforcement at stress points. The Proban FR-treated 100% cotton fabric provides flame resistance while the stitching and construction are designed to withstand tough industrial conditions.

Consider fabric weight (GSM), AR/AR-AR specifications, and the rated ATPV value. A higher GSM or higher ATPV rating generally indicates stronger protection but may feel heavier. Use the standard set (EN11611/EN11612/ NFPA70E) as a baseline for comparing FR performance across models on Fepy.
