Description
Waterproof FR Insulated Overalls Rated to -50C
Product Overview
FR compliance starts with the jacket, but the legs face the same cold, water, and flame exposure as the upper body. The Viking 3957FRP is a pair of FR insulated overalls rated to -50C. Built from 300-denier FR-treated Trilobal rip-stop polyester with PU backing and 250 gsm ThermoMAXX insulation, these freezer insulated overalls match the 3957FRJ parka for a complete head-to-boot FR system.
Key Features and Benefits of Viking 3957FRP FR Insulated Overalls
- The Viking 3957FRP uses 250 gsm ThermoMAXX insulation rated to -50C / -60F. The upper bib is insulated front and back for added core warmth.
- The 300-denier FR-treated Trilobal rip-stop polyester shell resists abrasion, puncture, rip, and snag. PU backing makes these FR insulated overalls waterproof and windproof.
- An 18-inch boot zipper with a 7-inch internal kick panel lets workers pull the overalls on and off over work boots. The kick panel reinforces the lower leg against scuffing.
- Heavy-duty elastic suspenders with a quick-release buckle distribute weight and allow fast removal. Two side waist gussets block wind at the waist.
- The bib holds an inner zippered pocket and a front storage pocket. Below the waist: two front slash pockets, one side cargo pocket, and a zippered fly with hook-and-loop flap.
- Two-inch Vi-brance reflective material in 4-inch contrasting tape meets WCB, Worksafe, and DOT configurations. These hi-vis FR overalls are available in black (CSA Z96-22 Class 1 / ANSI Class E) and orange (CSA Z96-22 Class 2 / ANSI Class E).
- These overalls share the same shell, insulation, and reflective tape as the matching Viking 3957FRJ parka. Pair them for a complete head-to-boot FR and hi-vis system.
The FR-treated polyester shell maintains flame resistance per ASTM D6413. PU backing makes these waterproof FR overalls block rain, snow, and cold storage condensation while remaining windproof. These flame resistant insulated overalls are not intended for hydrocarbon flash fires, electric arc hazards, or welding sparks.
ANSI/ISEA 107-2020 classifies lower-body garments as Class E. Black 3957FRP overalls meet CSA Z96-22 Class 1 and ANSI Class E; orange overalls meet CSA Z96-22 Class 2 and ANSI Class E. These freezer insulated overalls pair with a Class 2 or Class 3 upper garment for full-body hi-vis compliance.

Frequently Asked Questions
What are the best FR overalls for freezer workers?
The best FR overalls for freezer workers need flame resistance, insulation rated to freezer temperatures, and waterproofing. The Viking 3957FRP meets all three with 250 gsm ThermoMAXX insulation rated to -50C, a waterproof FR shell, and ANSI Class E hi-vis reflective tape.
What is the difference between FR overalls and FR bib pants?
FR overalls vs FR bib pants in Viking's lineup comes down to insulation level. The 3957FRP is a pair of freezer insulated overalls rated to -50C. The 3907FRWP is an insulated bib pant for milder cold. The 3907FRP is a non-insulated FR bib pant for warm-weather FR compliance.
What CSA class do I need for FR overalls?
What CSA class FR overalls do I need depends on your work environment. Black 3957FRP overalls are CSA Z96-22 Class 1 for non-roadway work. Orange overalls are Class 2 for roadway. ANSI Class E is the lower-body classification that pairs with a Class 2 or 3 upper garment.
Are Viking FR overalls waterproof?
Yes. The 3957FRP overalls are waterproof and windproof. The 300-denier Trilobal rip-stop polyester shell has PU backing that blocks water and wind while maintaining FR compliance per ASTM D6413. These waterproof FR overalls handle outdoor rain, snow, and cold storage condensation.
Which lasts longer, FR treated or inherently FR overalls?
The FR treated vs inherently FR overalls tradeoff is cost against longevity. FR-treated polyester, like the 3957FRP's shell, costs less but can lose FR properties with repeated washing. Inherently FR fabrics like Nomex or Westex UltraSoft retain FR properties for the garment's life at a higher price.
