FR401 Lightweight Stretch FR Trousers - Bizflame Work PPE

The FR401 Bizflame Work Lightweight Stretch Panelled FR Trousers are designed to deliver reliable flame resistant protection, lightweight comfort, and enhanced flexibility for professionals working in hazardous industrial environments. Combining durable FR cotton fabric with strategically placed stretch panels, these modern work trousers provide unrestricted movement and dependable performance throughout demanding workdays.

Manufactured using lightweight Bizflame Work fabric, the FR401 trousers provide certified protection against radiant, convective, and contact heat while maintaining breathability and wearer comfort. The lightweight 210g fabric construction helps reduce fatigue during extended shifts, making these trousers ideal for active industrial work environments.

Innovative stretch panelling in key movement areas and an integrated stretch crotch gusset allow maximum flexibility while bending, kneeling, climbing, or working in confined spaces. The side elastic waistband further enhances comfort and fit, helping workers stay comfortable throughout long hours on-site.

Engineered for practical workplace performance, these FR trousers feature eight functional storage pockets, including multi-functional thigh pockets, cargo pockets, rear pockets, and a dedicated rule pocket for easy access to essential tools and equipment. Two-tier knee pad pockets provide adjustable positioning options for added comfort and protection during kneeling tasks.

The trousers also feature an extendable leg length adjustable from 31" to 33" for a more personalised fit. Sew-on flame resistant industrial wash reflective tape improves visibility while maintaining durability through repeated industrial laundering.

Designed for specialist work environments, the metal-free non-magnetic construction makes these trousers suitable for ATEX environments and workplaces requiring metal detector friendly PPE.
