Portwest BX323 Ultimate Modular Hi-Vis 3-in-1 Rain Jacket – Product Description

The Portwest BX323 Ultimate Modular Hi-Vis 3-in-1 Rain Jacket is a highly versatile waterproof solution designed for workers who need maximum visibility, all-weather protection and flexible layering on site. This modular system delivers three garments in one: a premium hi-vis shell jacket, a detachable hi-vis vest, or both combined for EN ISO 20471 Class 3 visibility.

Built from Portwest Extreme waterproof and breathable stretch fabric, the BX323 offers a high-performance rating of EN 343 Class 4:3 X with a 20,000mm waterproof membrane and 15,000g/m²/24hr breathability, keeping you protected and comfortable in demanding outdoor conditions. Fully taped seams, a quick-dry knitted inner cuff and an adjustable hem ensure a secure, weatherproof seal throughout the working day.

The detachable vest packs neatly into the jacket pocket when not required and provides excellent functionality with radio loops, 6 pockets, pen pocket and ID pocket. The outer jacket adds a further nine pockets, including phone storage, tablet storage and two concealed pockets beside the front zip. Underarm ventilation zips improve airflow, while articulated shaping enhances movement during physical tasks.

Segmented heat-applied reflective tape across both garments ensures lightweight, flexible visibility. A helmet-compatible hood, twin-stitched seams and durable dirt-resistant contrast panels round out a jacket built for year-round performance across construction, highways, utilities and outdoor work environments.

This is a feature-rich hi-vis waterproof jacket ideal for UK operatives needing reliable protection, storage and adaptability in all weather conditions.
