Description
The Westex® UltraSoft® with AllOut® Insulated FR Bib with Reflective Tape (M905NEX) is built for harsh industrial environments where workers require warmth, weather protection, and high-level arc flash safety. Made in Canada using Westex® UltraSoft® with AllOut® fabric, this insulated bib provides windproof and water-repellent performance combined with CAT 4 arc-flash protection. Its midweight construction supports mobility for demanding tasks, while 3M™ reflective tape improves visibility in low-light conditions. Designed for durability and cold-weather performance, it delivers reliable protection without restricting movement.
Key Features
Westex® UltraSoft® with AllOut® Fabric: 8.5 oz FR twill made from 88% cotton and 12% high-tenacity nylon provides wind-resistant, water-repellent, and durable arc-rated protection.
FR Thermal Insulation: 10 oz quilted FR lining using Westex® InsulAir® helps retain warmth in cold environments while maintaining mobility.
CAT 4 Arc Flash Protection: ATPV rating of 46 cal/cm² supports high-level electrical hazard protection in demanding industrial settings.
High Visibility Reflective Tape: FR reflective tape on fluorescent FireWeave™ backing creates a horizontal visibility band around each leg.
Heavy-Duty Closure System: Concealed Nomex® taped brass zipper with storm flap and snap closures enhances durability and protection.
Secure Adjustable Fit: Elastic suspenders with adjustable Vislon buckles and an elastic waistband improve comfort and stability during movement.
Industrial-Grade Construction: High-resistance Nomex thread and bar-tacked stress points improve long-term durability in harsh work environments.
Functional Storage Design: Chest pocket with pencil division and large waist pockets with concealed snap closures provide convenient tool access.
Intended Use
