Portwest DX434 DX4 Hi-Vis Class 1 T-Shirt – Product Description

The Portwest DX434 DX4 Hi-Vis Class 1 T-Shirt is a lightweight and breathable high visibility top designed for workers who need cooling performance, comfort and unrestricted movement. Made from EzeeCool moisture wicking polyester pin mesh, it helps keep the wearer cool and dry by drawing moisture away from the skin during active or warm weather work.

The slim fit design offers a modern athletic look, while the contrast collar and fluorescent stripe provide clean professional styling suitable for corporate branding and uniform programmes. HiVisTex Pro segmented reflective tape enhances visibility without restricting movement, making this T-shirt ideal for bending, stretching and physical tasks where flexibility is essential.

A radio loop provides a secure attachment point for communication devices, and the fabric offers UPF 40 sun protection for outdoor use. The T-shirt maintains colour vibrancy and EN ISO 20471 certification for up to fifty washes, ensuring long term reliability.

Certified to EN ISO 20471 Class 1, the DX434 is suitable for construction, logistics, driving, maintenance, utilities and general outdoor work during warmer months.
