Frequently Asked Questions

What does EN343 Class 4:3 mean?

EN343 is the European standard for protective clothing against rain. The first number (4) indicates the highest level of water penetration resistance, meaning the jacket withstands a water column of at least 8,000Pa (equivalent to approximately 8,000mm). The second number (3) indicates excellent breathability. This jacket exceeds these minimums with 11,000mm waterproofing and 50,000g/m²/24hrs breathability—among the best ratings available in workwear.

Why choose a Class 1 hi-vis jacket instead of Class 3?

Class 1 hi-vis jackets like the PW368 are ideal for environments where some visibility is required but full hi-vis coverage isn't mandated. The black lower panel offers practical benefits: it hides dirt, oil, and daily wear, maintaining a professional appearance. Class 1 is suitable for controlled work environments, warehouses, and areas where workers aren't exposed to moving traffic. Always check your workplace risk assessment for specific hi-vis requirements.

What is PFAS-free Texpel™ Splash Eco?

Texpel™ Splash Eco is Portwest's environmentally responsible water-repellent finish that causes water to bead away from the fabric surface. Unlike traditional DWR (Durable Water Repellent) treatments, it's PFAS-free—meaning it doesn't contain per- and polyfluoroalkyl substances that can persist in the environment. This eco-conscious finish delivers excellent water repellency while reducing environmental impact.

How does the breathability rating work?

Breathability is measured as MVP (Moisture Vapour Permeability) in g/m²/24hrs—the grams of water vapour that can pass through one square metre of fabric in 24 hours. The PW368's rating of 50,000g/m²/24hrs is exceptionally high, meaning perspiration can escape quickly. Combined with the underarm pit zips, this prevents that clammy, overheated feeling common with less breathable waterproofs, keeping you comfortable during physical work.

How should I care for this jacket?

Machine wash at 40°C using a mild detergent. Do not use bleach or fabric softener as these can damage the waterproof membrane and DWR finish. Do not tumble dry—hang or drip dry instead. Do not iron. The jacket is rated for up to 25 washes while maintaining its performance. Periodically reactivating the DWR by tumble drying on low heat (if care label permits) or using a specialist reproofing spray can help maintain water beading.
