Flame-Resistant Bib Pants 4XL

These Viking 3907FRP bib pants deliver flame-resistant rain protection in a men's 4XL size with a 33 in inseam. The polyester shell weighs 13.5 oz and meets ANSI/ISEA 107, ASTM D6413, CAN/CGSB-4.2 No. 27.10 and CSA Z96-15 standards. A polyester lining is included for added comfort. The black finish has no high-visibility rating.

Hook-and-Loop Waist and Ankle Design

An adjustable hook-and-loop waist closure accommodates up to a 48 in maximum waist size. Open ankles allow the pants to be pulled over work boots without removing footwear. Four outside pockets and one inside pocket provide storage for tools or personal items. The 2 in Vi-Brance reflective tape with 4 in contrasting tape enhances visibility in low-light conditions.

Upgrade from Basic Rain Gear

These pants replace standard rainwear that lacks flame-resistant certification and ANSI/ISEA 107 compliance. The jump is worth it when job sites require FR protection to ASTM D6413 and CSA Z96-15 alongside wet-weather performance. Workers who need high-visibility Class E certification should note this model does not carry that rating.

Questions about this item

How much does the 13.5 oz fabric weight restrict movement during a full shift?

The 13.5 oz polyester shell with polyester lining adds noticeable mass but remains pliable; most wearers report full range of motion after the first hour of break-in.

Do the hook-and-loop waist tabs stay secure and quiet when kneeling all day?

The hook-and-loop closure holds the 48 in maximum waist without slipping, and the soft-loop face prevents the loud rip sound that hard Velcro makes on concrete.

Besides the pants, what PPE does the ANSI Class E rating require me to wear?

Class E certifies the bib pants only; you must add a compliant Class 2 or 3 vest or jacket to meet the full ANSI/ISEA 107 high-visibility ensemble.
