Maximum Visibility with EN ISO 20471 Class 3 and Rail Industry Certification
High visibility workwear serves as essential protection in environments where workers operate near moving vehicles, heavy equipment, or active rail lines. The Portwest S548 Hi Vis Ultrasonic Heated Tunnel Jacket in orange/black achieves EN ISO 20471 Class 3 certification, representing the highest classification for high visibility garments. This certification guarantees maximum conspicuity through strategically positioned fluorescent orange background material and precisely placed reflective tape.
Class 3 certification requires specific minimum areas of both fluorescent and reflective materials, ensuring workers remain visible from all angles and at substantial distances. Whether performing roadside maintenance, working in construction zones, or operating near active railways, the S548 orange variant ensures workers can be clearly identified by equipment operators, drivers, and train personnel.
Critically, the orange colorway also meets RIS-3279-TOM Issue 2 standards, the specific rail industry safety requirement for trackside workers and railway maintenance personnel. This dual certification makes the S548 orange/black jacket particularly valuable for rail industry applications where RIS compliance is mandatory. Organizations operating in railway environments must ensure their workers wear RIS-certified high visibility garments, making this jacket an essential investment for rail contractors, maintenance crews, and transportation authorities.
Premium Fabric Construction and Weather Resistance
The shell fabric utilizes 100% polyester pongee ripstop with a TPU membrane bonded to 100% polyester tricot knit, creating a robust 160g outer layer engineered for demanding industrial environments. This technical fabric combination delivers multiple performance advantages that standard workwear cannot provide.
The ripstop weave pattern prevents tears from propagating across the fabric, dramatically extending garment lifespan even when subjected to snags, abrasions, and rough handling common in construction and industrial settings. The bonded TPU membrane provides exceptional water resistance while maintaining breathability, preventing internal moisture accumulation that compromises thermal efficiency and worker comfort.
The premium water-resistant finish actively sheds rain, snow, sleet, and moisture, keeping workers dry throughout their shifts regardless of weather conditions. This water resistance works synergistically with the heated panels to maintain optimal thermal comfort, as dry clothing provides significantly better insulation than moisture-laden fabrics.
Additionally, the jacket features a premium stain-resistant finish that repels oil, water, and grime—substances frequently encountered in automotive, industrial, construction, and rail maintenance environments. This stain resistance preserves the jacket’s professional appearance and maintains high visibility properties even after repeated exposure to harsh contaminants. Clean, bright high visibility garments provide better conspicuity than soiled workwear, making stain resistance a critical safety feature.
Revolutionary Ultrasonic Baffle Technology
Traditional quilted jackets employ stitched baffles that create thousands of needle holes throughout the fabric, compromising water resistance and creating pathways for cold air infiltration. The S548 employs innovative heat-sealed ultrasonic baffle technology, completely eliminating stitching holes from the construction.
This ultrasonic welding process creates permanent bonds between fabric layers without introducing penetrations where moisture can enter or insulation can shift. The result is significantly enhanced water resistance and consistent thermal performance throughout the jacket’s service life. The fully lined and padded interior effectively traps body heat, working in concert with the carbon fiber heating elements to maximize warmth retention and minimize heat loss.
This construction method represents a substantial advancement over conventional manufacturing techniques, ensuring the jacket maintains its protective properties through countless work cycles, wash cycles, and exposure to demanding conditions.
Comprehensive Design Features for Working Professionals
Beyond technological innovations, the S548 orange/black heated jacket incorporates numerous practical design elements that enhance functionality, comfort, and safety during demanding workdays:
Secure Fit and Adjustability: Elasticated cuffs create an effective seal at the wrists, preventing cold air infiltration and heat loss through the sleeves. The drawcord adjustable hem enables workers to customize the fit, accommodating different body types and varying base layer combinations. This adjustability ensures the jacket remains comfortable whether worn over light clothing or heavier insulating layers.
Enhanced Comfort Elements: The chin guard with internal storm flap provides protection against zipper irritation and prevents cold air from entering at the neckline—a common weakness in jacket designs. These thoughtful details reflect Portwest’s understanding of real-world working conditions where comfort directly impacts worker productivity, safety awareness, and job satisfaction.
Convenient Storage Solutions: Multiple zipped pockets provide secure storage for essential tools, personal items, mobile devices, and work documents. Easy-grip pullers attached to all zippers enable operation with gloved hands, eliminating frustration and maintaining workflow efficiency in cold conditions when removing gloves risks discomfort or frostbite.
Professional Appearance: Contrast black panels strategically positioned at high-wear areas provide protection against visible dirt accumulation, maintaining a professional appearance throughout extended work periods. This design consideration reduces cleaning frequency while ensuring workers present a professional image on job sites, client locations, and public-facing work areas.
Front Zip Access: The full-length front zipper provides easy access for donning and removal, while also enabling ventilation control when transitioning between cold outdoor environments and heated vehicles or indoor spaces.
Year-Round Sun Protection and Extended Versatility
While engineered primarily for cold weather protection, the S548 orange/black jacket also meets EN 13758 standards with UPF 40+ sun protection rating. This certification indicates the fabric blocks at least 97.5% of harmful UV radiation, protecting skin from sun damage during outdoor work assignments.
This sun protection feature extends the jacket’s utility beyond winter months, making it suitable for cool morning shifts that transition into sunny afternoons, spring and fall weather conditions, and high-altitude environments where both cold temperatures and intense UV exposure present simultaneous hazards. The ability to deactivate heating elements while retaining high visibility, water resistance, and durable construction makes the S548 a versatile four-season investment for outdoor work requirements.
