Portwest RT23 T-Shirt: High-Visibility Engineering, Railway Certification, and Moisture Management

The RT23 is a technical high-visibility garment (Class 2) designed specifically for operations in medium-risk environments where rapid visual detection is the primary safety factor. Made from 175g 100% polyester knit fabric, this t-shirt integrates active breathability technology, allowing for efficient evacuation of body heat and sweat. It is standard equipment for personnel in road, rail, and logistics infrastructure operating in variable lighting conditions or intense sun exposure.

Technical Features and Operational Capabilities

• RIS 3279 TOM Certification (Orange): This garment meets the strict safety requirements of the railway industry (fluorescent orange), ensuring that the worker is perfectly distinguishable even against saturated backgrounds or in low-light conditions.
• Active Breathability Technology: The technical knit fabric facilitates airflow and immediate evaporation of internal moisture. This microclimate management is essential for reducing thermal stress during intense physical outdoor workdays.
• 360° Visibility (EN ISO 20471 Class 2): High-quality reflective tapes are strategically placed on the torso and shoulders, ensuring the operator's visibility from any angle of approach of machinery or vehicles.
• Environmental Protection (UPF 40+): The fabric provides 98% UV radiation blocking, which is a necessary protective measure for the dermatological health of personnel exposed to prolonged sun exposure.

Safety Notice and Limitations of Use

IMPORTANT: This garment is strictly designed to improve user visibility. It is NOT flame-resistant, not anti-static, and offers no protection against thermal risks, electrical arcs, or fire. Its use is strictly prohibited in environments where technical protective clothing (FR/ARC) is required. This t-shirt should not replace specialized PPE that your workplace risk assessment may require.

Maintenance and Care Instructions

• Washing: Machine wash at 40°C maximum. DO NOT use fabric softeners, as these coat synthetic fibers and reflective tapes, drastically reducing retroreflection and breathability.
• Drying: Air dry or tumble dry on low heat. Avoid high-temperature industrial drying.
• Ironing: DO NOT iron over reflective tapes; direct heat deforms the reflective material and invalidates its certification.
• Inspection: Daily check that reflective tapes show no abrasions, cracks, or excessive dirt accumulation. A garment with damaged tapes loses its Class 2 certification and must be removed from service.
