When worker safety meets all-day comfort, the Portwest FR709 Modaflame Knit Hi-Vis Two Tone FR Crew in Yellow/Black stands in a class of its own. As an Authorized Portwest Distributor, TECHACS Safety Solutions proudly offers this premium inherent flame-resistant hi-vis crew neck that delivers permanent FR protection, ANSI/ISEA 107 Type R Class 3 visibility, and exceptional comfort for electricians, utility workers, oil & gas professionals, and anyone working in hazardous environments.
Why Choose the Portwest FR709 Modaflame Knit Hi-Vis FR Crew?
The FR709 is built using revolutionary Modaflame™ Knit HV fabric – a 280g (8oz) blend of 60% modacrylic, 39% cotton, and 1% carbon fiber. Unlike treated fabrics that lose protection over time, Modaflame Knit is inherently flame resistant – meaning the FR properties are built into the yarn itself and will never wash out, no matter how many industrial launderings it goes through.
Key performance highlights:
- ARC Rating: ATPV 9 cal/cm² (ARC2) – Proven protection against arc flash hazards
- ANSI/ISEA 107 Type R Class 3 high visibility for day and night work
- NFPA 70E, ASTM F1506, EN ISO 11612 (A1+A2, B1, C1), EN 1149-5 compliant
- 40+ UPF – Blocks 98% of harmful UV rays
- Heat-applied segmented reflective tape – lighter, more breathable, and flexible than traditional tape
- High cotton content (39%) for superior softness and all-day comfort
Real-World Applications of the Portwest FR709
This versatile two-tone hi-vis FR crew is trusted across multiple high-risk industries:
- Electrical & utility workers (arc flash protection)
- Oil, gas & petrochemical (flash fire hazards)
- Welding & metal fabrication
- Railroad & transportation
- Renewable energy (wind & solar farms)
- General manufacturing & construction
The contrasting black panels on the lower torso and sleeves help hide dirt and grime – perfect for tough, dirty jobs where appearance still matters.
Comfort That Actually Feels Like Regular Workwear
Most FR clothing feels stiff and heavy. The FR709 breaks that stereotype. The interlock knit construction combined with the high cotton content gives it the soft hand-feel of your favorite t-shirt while maintaining full flame-resistant and hi-vis performance. Crew neck design, raglan sleeves, and lightweight 280g fabric keep you cool and moving freely all shift long.
