Portwest B304 Hi Vis Hoodie Mens EN ISO 20471 Class 3 with Bio Motion Tape, 300g Polycotton, Orange (Size L)
Product description
What it is and what it’s for
The Portwest B304 is a high visibility hoodie designed for workers who need to stay visible in low-light conditions while staying warm on site. It combines a fluorescent outer shell with a bio motion reflective tape pattern to help drivers and operators spot movement more quickly. The garment is EN ISO 20471 Class 3 certified and ANSI/ISEA 107 Type R Class 3, which places it firmly in the higher end of the visibility spectrum for outdoor and site work. It’s particularly suited to warehouse, construction, rail, and roadside tasks where you’re active and need reliable protection from the elements.
Material and build quality
On the fabric side, you get a brushed-back 65% polyester / 35% cotton knit at 300g/m². The brushed interior adds warmth for chilly starts without needing to layer up excessively. Cuffs and hem are ribbed to seal in warmth during long shifts, and the hood is cut to sit under a hard hat so you can layer safely without compromising PPE rules.
Design and practicality
The standout feature is the bio motion reflective tape pattern that follows the natural lines of the body. This isn’t just cosmetic, it’s a practical aid for visibility as you move around a busy site. A generous kangaroo pocket serves as a hands warmer and a small storage space for gloves or tools between tasks. The orange colourway, aside from being highly visible, is chosen for rail and roadside work where conspicuity matters.
Performance in real use
If you prioritise warmth and visibility, the B304 delivers on both fronts. It’s not a windbreaker or a rainproof shell, but it does contribute to warmth on cool mornings and helps you stay noticeable as you switch between tasks. The fabric is reported to retain EN ISO 20471 certification after multiple washes, up to about 50 cycles at 40°C. Do bear in mind that higher durability in continuous wash cycles often hinges on following care guidelines.
Strengths and potential drawbacks
What stands out is the combination of high-visibility standards with a comfortable fleece-like interior and a fit that works with hooded layering under PPE. The hood is specifically designed not to interfere with helmets, which is a practical plus on site. On the flip side, this hoodie isn’t a substitute for a weatherproof jacket. It provides warmth and visibility, but if you’re facing prolonged rain or heavy winds, you’ll likely need additional outerwear. Also, the orange version aligns with certain rail safety standards, if your worksite requires a different colour, the selection may be limited.
Who it’s for
This garment is well suited to workers on construction sites, warehouses, and rail yards who need high visibility, warmth, and practical storage on cold days. It’s also a reasonable option for those who spend long periods outdoors and want a garment that remains comfortable while meeting strict safety standards.
Who it’s not for
If your environment is primarily indoors, extremely wet, or requires a more tailored PPE silhouette, this hoodie may feel over-specified or under-protected in wet conditions. If you need full rain protection, this piece should be paired with a waterproof layer. If you require a non-orange visibility option for other safety regimes, choices may be more limited.
When it makes sense to buy
Buy when you need a certified high-visibility garment that can be worn as a mid-layer in cool weather or as a standalone outer layer in milder conditions. It’s useful when you want a hands-on, warm option that won’t compromise PPE fit under a hard hat and that stays visible across different tasks.
What to check before purchasing
- Confirm size and fit with your PPE layering needs, especially if you plan to wear a hard hat over the hood.
- Consider whether the orange colour meets your site’s RIS 3279 TOM or other regulatory requirements.
- Review washing instructions to ensure the EN ISO 20471 Class 3 guarantee remains intact after repeated launderings.
- Think about the climate you work in: the 300g brushed fabric is warm, but may feel heavy in milder environments.
How it compares to alternative approaches
If you mainly work indoors or in dry, mild climates, a lighter high-visibility fleece or windbreaker might be a better fit. For sites with very strict visibility standards or tasks that involve a lot of movement, this B304 offers a balanced mix of warmth, visibility, and practical storage. It isn’t the ultimate rain-proofer or a shell, but it reduces the risk of being overlooked in busy environments while keeping you snug during cooler shifts.
FAQ (practical highlights)
- How does the bio motion tape help in practice? It follows body contours to boost conspicuity as you move, which can aid drivers and operators in spotting you sooner.
- How durable is the fabric after washing? The garment is designed to retain EN ISO 20471 certification for up to around 50 wash cycles at 40°C, subject to care guidance.
- Is it suitable for summer work? It provides warmth and UV protection (40+ UPF), but it may feel warm in hot conditions, layering or lighter gear may be preferred.
Decision point: Should you buy it?
Should you buy it? If your work involves outdoor tasks with a need for strong visibility and warmth, and you operate under PPE guidelines that allow a hooded layer under a hard hat, this Portwest B304 offers clear value for purpose. It’s a sensible choice for those prioritising compliance with EN ISO 20471 Class 3 and practical on-site utility, provided you’re comfortable with a dedicated orange option and the modest limits of a warm mid-layer.
