When workplace safety meets cutting-edge comfort technology, the result is the Portwest S397 Hi-Vis Mesh Insert Class 3 T-Shirt S/S Yellow. As an authorized Portwest dealer, TECHACS Safety Solutions proudly offers this premium high-visibility garment that sets new standards for worker protection and comfort in demanding industrial environments. 
Revolutionary Design Meets ANSI Class 3 Protection
The S397 Hi-Vis Mesh Insert Class 3 T-Shirt represents a breakthrough in occupational safety wear. This short-sleeve t-shirt combines Portwest’s innovative Cotton Comfort fabric with strategic mesh inserts to deliver unparalleled breathability without compromising visibility or safety standards. The lightweight construction ensures workers remain comfortable during extended shifts while maintaining full ANSI/ISEA 107 Type R Class 3 compliance.
The garment’s distinctive yellow color provides maximum visibility in various lighting conditions, while the reflective tape placement follows strict safety protocols to ensure 360-degree visibility. This makes the S397 an essential piece of safety equipment for construction workers, traffic control personnel, emergency responders, and anyone working in high-risk environments where visibility is critical.
Advanced Fabric Technology for Superior Performance
What sets the S397 apart from standard high-visibility shirts is its sophisticated fabric engineering. The 100% polyester bird eye knit shell fabric weighs just 4.5oz, providing durability without bulk. This lightweight construction is complemented by 100% polyester mesh contrast panels that create targeted ventilation zones, allowing air circulation where workers need it most.
The Cotton Comfort fabric technology incorporates moisture-wicking properties that draw perspiration away from the skin, keeping workers dry and comfortable even in challenging conditions. This advanced textile engineering means workers can maintain peak performance without the distraction of uncomfortable, saturated clothing.
Premium Features That Make a Difference
Every detail of the S397 has been carefully considered to enhance worker comfort and safety. The taped neck seam eliminates irritation during prolonged wear, while the tape-free pocket provides an ideal location for corporate branding without interfering with reflective elements. The quality Texpel™ Wicking fabric finish not only enhances moisture management but also aids in stain removal, keeping the garment looking professional wash after wash.
One of the standout features is the 40+ UPF rating that blocks 98% of harmful UV rays, providing crucial sun protection for outdoor workers. This level of UV protection transforms the S397 from simple safety wear into comprehensive worker protection equipment that addresses multiple workplace hazards simultaneously.
Durability and Compliance You Can Trust
The S397 Hi-Vis Mesh Insert Class 3 T-Shirt maintains its ANSI/ISEA 107 certification even after 50 wash cycles, demonstrating exceptional durability and long-term value. This washing resilience means companies can rely on consistent safety performance throughout the garment’s extended service life, reducing replacement costs and ensuring continuous compliance with safety regulations.
The breathable fabric construction and quick-dry properties mean the shirt maintains its shape and performance characteristics even with frequent washing, making it ideal for industries where daily laundering is necessary for hygiene or safety protocols.
Sizing and Availability for Every Worker
Understanding that safety equipment must fit properly to be effective, the S397 is available in sizes up to 6XL, ensuring that workers of all body types can benefit from Class 3 protection. This comprehensive sizing range reflects TECHACS Safety Solutions’ commitment to inclusive safety practices that protect every member of the workforce.
