The Pioneer V339 flame-resistant shirt (model 339SFA) brings together in a single garment the comfort of a 100% cotton knit and the peace of mind of certified flame-resistant protection. Made from a 7.5 oz (250 g/m2) preshrunk cotton treated for flame resistance, it delivers a soft, breathable feel while standing up to the dangers of electric arc and flame. Its fluorescent orange color ensures heightened visibility on job sites, industrial facilities and traffic zones, both in daylight and in low-light conditions. Available from size S to 5XL, it fits nearly every worker build. Priced at $92.45, it is a smart investment for anyone working near ignition sources or electrical hazards.
The V339 does more than stay visible: it actively protects. It meets CGSB 155.20-2017, CSA Z96-22 class 1 level 2 and class 1 level FR, ANSI/ISEA 107-2020 class 1 type O, ASTM F1506-10a, NFPA 70E and CSA Z462-15. This stack of certifications confirms the garment has been rigorously tested for environments where electric arc risks and high-visibility requirements coexist. It is rated ARC level 2 and FR, making it a reliable ally for electricians, line workers and industrial maintenance staff.
This shirt shows an ATPV (Arc Thermal Performance Value) of 9 cal/cm2 and a TPP (Thermal Protective Performance) value of 7.3 cal/cm2. These figures reflect the fabric's ability to slow the transfer of heat toward the skin during a thermal incident. Please note that the stated ATPV and TPP values match those printed directly on the garment, ensuring full transparency and exemplary traceability for your safety programs.
The choice of 100% preshrunk cotton is no accident. Preshrinking limits garment distortion wash after wash, preserving the fit and coverage over time. Cotton, a naturally breathable material, reduces discomfort from perspiration during long work days. The flame-resistant treatment is built into the fabric to guarantee consistent protection, season after season.
Prefer a more discreet shade? This same flame-resistant shirt is also offered in a black version under reference V340. The black version keeps the exact same flame-resistant and electric arc protection, while offering a more understated look and better concealment of dirt. Note, however, that black is not a high-visibility color: for traffic zones, the orange version remains recommended.
The V339 is the orange high-visibility version, while the V340 is the black version. Both offer identical flame-resistant and electric arc protection; only the color and visibility level differ.
They are measures of the fabric's thermal performance against an electric arc and a thermal exposure. The higher the value, the greater the protection against heat transfer. These values match those printed on the garment.
Yes. It meets standards including NFPA 70E, CSA Z462-15, ASTM F1506-10a and is rated ARC level 2, making it appropriate for many tasks near electric arc hazards.
The V339 is offered from size S to 5XL, covering a wide range of worker builds.
Preshrinking greatly reduces additional shrinkage in the wash, helping to keep the garment's fit and coverage over time.
To complete your flame-resistant protection, start with the Black (V340) version of this shirt, the orange flame-resistant Shirt (V130), the orange flame-resistant Pants (V7765) and the flame-resistant Arc 2 Gloves (GS13FRNE).
Under “Accessories” at the bottom of the page, complete your equipment with the orange flame-resistant Arc 2 Coverall (V1765), the Blue (V131) flame-resistant shirt, the blue flame-resistant Trousers (V7764) and the red DANGER barricade Tape (ECT3RE9).
