Portwest T166 PW3 Hi-Vis Rain Jacket – Product Description

The Portwest T166 PW3 Hi-Vis Rain Jacket is a premium 3-layer waterproof jacket engineered for professionals who need reliable weather protection, breathability and unrestricted movement on site. Built from Portwest Extreme soft-touch stretch 3-layer fabric, it provides a durable waterproof barrier while maintaining a comfortable, flexible fit.

Certified to EN 343 Class 4:4, the jacket delivers top-level waterproof and breathability performance, supported by fully taped seams, a narrow triple storm flap, and a two-way front zip for fast access even when wearing a harness. Ventilated pockets and stretch panelling help regulate temperature during active work, making it ideal for construction, civils, utilities, rail (orange only) and all-weather outdoor tasks.

The helmet-compatible hood features a shaped peak and 3-point adjustment system for secure protection, while the extended back hem guards against dirt and rain. Acti-Reach™ one-panel construction enhances mobility when reaching, bending and twisting, making this jacket exceptionally ergonomic. Pre-bent sleeves and raglan shaping further support freedom of movement.

Additional features include radio loops, an ID holder, 40+ UPF sun protection, and heat-applied segmented reflective tape for lightweight visibility. Certified to maintain EN ISO 20471 compliance after 50 washes, the T166 is designed for long-term durability in tough working environments.
