Description
Waterproof FR Pants with Detachable Bib and Boot Zippers
Product Overview
Most FR sites enforce compliance head to toe, but lower-body rain protection gets overlooked until the first downpour. The Viking 3907FRP is a waterproof, windproof FR bib pants built with the same 300D Trilobal rip-stop polyester shell as the matching 3907FRJ jacket. Detachable bib, 13-inch boot zippers, and quick-release suspenders make these flame resistant bib pants fast to put on over work boots.
Key Features and Benefits of Viking 3907FRP FR Bib Pants
- The 300D FR-treated Trilobal rip-stop polyester shell with PU backing is waterproof, windproof, and resistant to abrasion, puncture, rips, and snags. These waterproof FR pants block rain from reaching the legs without trapping heat, because there is no insulation layer.
- 13-inch boot zippers with protective cover and hook-and-loop fastener let you pull the pants on over work boots without unlacing. The zipper cover keeps rain out of the boot opening.
- Detachable bib disconnects from the waist, turning these into standalone rain pants when the bib is not needed. An elasticized waist with zippered fly and hook-and-loop flap provides a weather-tight closure at the front.
- Heavy-duty elastic suspenders with quick-release buckles distribute the weight across the shoulders. The quick-release lets you drop the bib in seconds if you need to remove the pants on site.
- 2" Vi-brance reflective tape in 4" contrasting background meets WCB, Worksafe, and DOT configuration. The orange and green variants qualify as hi-vis FR pants under CSA Z96-22 Class 2.
- FR treatment passes CAN/CGSB-4.2 No.27.10 and ASTM D6413. The shell self-extinguishes on momentary contact with open flame, maintaining FR compliance in general industrial environments.
- Pairs with the matching 3907FRJ FR rain jacket for a complete non-insulated FR rain suit. Both pieces share the same 300D shell material and reflective tape configuration.

What ANSI Class E Means for FR Bib Pants
All three colors of the Viking 3907FRP carry the ANSI/ISEA 107-2020 Class E classification. Class E is the ANSI designation for lower-body hi-vis garments. It is not standalone: wear Class E pants with a Class 2 or Class 3 jacket to achieve full-body hi-vis coverage.
When the orange Viking 3907FRP bib pants (CSA Class 2, ANSI Class E) are worn with the orange 3907FRJ jacket (CSA Class 2, ANSI Type R Class 3), the combination provides full Type R Class 3 coverage from collar to boot. The CSA classification depends on color: black meets CSA Z96-22 Class 1, Level 2, while orange and green meet Class 2, Level 2. Understanding what is ANSI Class E hi-vis helps when specifying lower-body FR garments for procurement.
When deciding whether you need FR bib pants or FR overalls, the question is temperature. The 3907FRP handles rain in mild to warm weather. The 3907FRWP adds insulation for cold conditions. The 3957FRP freezer insulated FR overalls include 250gsm ThermoMAXX rated to -50C for extreme cold.
