The FB31 3000 Over-Trousers are premium flame resistant protective over-trousers designed to provide advanced lower body protection in high-risk firefighting and hazardous industrial environments. Engineered for durability, weather resistance, and freedom of movement, these over-trousers deliver dependable multi-layer protection against heat, flames, and harsh weather conditions.

Constructed using a high-performance Nomex® and Lenzing® FR Viscose fabric blend, the FB31 offers reliable flame resistant protection together with breathable waterproof performance for demanding operational environments.

Designed to protect against radiant, convective, and contact heat, these over-trousers provide certified protection for professionals working in hazardous conditions where thermal risks are present.

The waterproof and breathable construction features fully taped seams that help prevent water penetration while allowing moisture vapour to escape, helping keep the wearer dry and comfortable during prolonged wear.

The ergonomic design provides a high level of freedom of movement, supporting comfort and flexibility during active work situations.

A low-cut crotch seam enhances mobility and wearer comfort, particularly during bending, kneeling, and physically demanding tasks.

The non-detachable adjustable shoulder braces ensure a secure fit while evenly distributing weight for improved comfort during extended wear.

An ergonomic quick release buckle system allows fast and convenient fitting and removal while maintaining a secure fit during use.

The half elasticated waistband provides additional comfort and flexibility while helping achieve a secure fit over workwear and protective layers.

A concealed hook and loop front fastening offers secure closure while maintaining a clean professional appearance.

The anti-wicking strip at the hem helps reduce water ingress from the lower leg area, improving overall weather protection during wet working conditions.

Sewn flame resistant industrial wash reflective tape enhances visibility and helps maintain workplace safety in low light conditions.

The advanced layered construction includes a moisture barrier and thermal protective layers that improve thermal insulation and wearer comfort in hazardous environments.

Manufactured to professional safety standards, the FB31 over-trousers are CE certified and classified as CE-CAT III.
