Portwest RT23 Hi-Vis Orange T-Shirt Short Sleeve

The Portwest RT23 Hi-Vis Orange Short Sleeve T-Shirt is a comfortable and highly visible workwear garment designed for professionals working in rail, construction, highways, and other safety-critical environments. Combining lightweight breathable fabric with certified high visibility protection, this t-shirt is ideal for warmer conditions, indoor work areas, and physically demanding tasks where comfort and safety are equally important.

Manufactured from 100% polyester bird-eye knit fabric (150g), the t-shirt offers excellent breathability and moisture management. The bird-eye knit construction allows air to circulate through the fabric, helping to draw moisture away from the body and keep the wearer cool and dry throughout the working day.

The garment features a Texpel™ Wicking fabric finish, which enhances moisture movement away from the skin while also helping improve drying performance and stain release. This makes the t-shirt particularly suitable for active work environments where comfort and cleanliness are important.

Designed with practicality and comfort in mind, the t-shirt includes a classic crew neck design with a taped neck seam, helping to prevent irritation and improve durability during regular wear. A generous fit provides additional comfort and freedom of movement, making it suitable for extended use across a wide range of working conditions.

For improved safety, the garment incorporates high-visibility reflective tape, ensuring the wearer remains easily visible in low-light conditions or high-risk environments such as roadsides, construction sites, and rail infrastructure.

The fabric also provides 40+ UPF protection, blocking up to 98% of harmful UV rays when working outdoors.

The Portwest RT23 is certified to EN ISO 20471 Class 2 high visibility standards and complies with RIS 3279-TOM rail industry requirements (orange version), making it suitable for rail workers. The garment also meets ANSI/ISEA 107 Type R Class 2 and Type P Class 2 standards, ensuring internationally recognised safety compliance. It maintains its high-visibility certification for up to 50 washes, ensuring long-term reliability and performance.

Combining breathability, comfort, and certified high visibility protection, the Portwest RT23 Hi-Vis T-Shirt is a practical and reliable workwear choice for professionals operating in demanding environments.
