Stanco TT44670 Lightweight 44 Cal CAT 4 Arc Flash Bib Overalls

The Stanco TT44670 is engineered for professionals who need maximum arc flash protection without the debilitating heat and weight of standard gear. These bib overalls are over 40% lighter than conventional cotton-based CAT 4 garments, drastically reducing worker fatigue and the risk of heat-related illness during long shifts in high-voltage environments.

The high-performance construction features an inherent 5 oz. FR outer shell paired with a 6 oz. liner. This dual-layer system achieves a formidable 44 cal/cm² rating while maintaining a total weight of just 11 oz/yd². Generously cut to allow a full range of motion, these overalls ensure that safety never feels restrictive.

The Lightweight Difference:

• Advanced NORFAB Fabric: Utilizes a lightweight synthetic blend that provides superior thermal insulation compared to heavier, bulkier natural fibers.

• Dual-Hazard Certified: Rated for both Arc Flash and Flash Fire applications, making these overalls ideal for complex utility and industrial maintenance.

• Superior Ergonomics: Generously sized for ease of movement over daily work clothes, featuring adjustable straps to ensure a secure, personalized fit.

Key Features:

• Extreme Protection: Certified NFPA 70E CAT 4 with a high 44 cal/cm² ATPV.

• Worker Comfort: The 11 oz. total fabric weight keeps the wearer significantly cooler than standard 20+ oz. CAT 4 suits.
