Flame-Resistant Insulated Rain Bib Pants

Viking 3907FRWP-M flame-resistant insulated rain bib pants are built for workers who face cold, wet conditions and need certified flame resistance. The polyester shell and lining weigh 13.5 oz and meet ANSI/ISEA 107, ASTM D6413 and CSA Z96-15 standards. Hook-and-loop waist closure and open ankles allow quick donning over boots. Five total pockets provide secure storage for tools and personal items.

Medium size with 30 1/2 in inseam

This size fits men who wear a medium and need a 30 1/2 in inseam with up to a 33 in waist. The insulated construction suits cold-weather outdoor work where flame-resistant ratings are required. Workers who need high-visibility colours or ANSI Class 2 or 3 garments should look elsewhere. Buyers needing a different inseam, waist range or women's sizing will need another model.

Certified to ANSI/ISEA 107 Class E and ASTM D6413

The single specification that decides fit-for-purpose is the flame-resistance certification to ASTM D6413 combined with ANSI/ISEA 107 Class E and CSA Z96-15 compliance. If your safety plan requires these exact standards, the pants qualify; if a different FR standard or a higher visibility class is mandated, they do not.

Questions about this item

Will the hook-and-loop waist closure need replacing after repeated use?

The hook-and-loop waist closure is designed for repeated fastening; if grip weakens over time, the closure can be serviced or replaced by a workwear repair shop.

What limits comfort during a full shift in wet, cold conditions?

The 13.5 oz insulated polyester shell with polyester lining keeps warmth in, but the open ankle design and lack of ventilation zips can trap heat and moisture during sustained high activity.

How much heat builds up when wearing these bib pants all day?

The 13.5 oz flame-resistant insulated construction retains body heat for cold protection, so extended wear in mild or heated environments will feel warm; the open ankles provide the only passive airflow.
