Description
This hi-vis hooded sweatshirt is high visibility clothing for professionals who work daily in environments with traffic, heavy machinery or other moving hazards. The model is suitable for road construction, logistics, railway maintenance and similar sectors where high visibility is legally or contractually required. The construction combines a sturdy 300 g/m² polyester-cotton blend with a hood for extra protection in changing weather.
For which working conditions is the Portwest B304 hi-vis hooded sweatshirt suitable?
The Portwest B304 is suitable for outdoor work where both visibility and basic protection against cold or wind are required, such as road maintenance, railway work and construction logistics.
The sweatshirt complies with EN ISO 20471 Class 3, the highest class for high visibility clothing. This means that it combines the largest surface areas of fluorescent material and retroreflective strips, making it most suitable for environments with fast-moving traffic or limited visibility. Thanks to the RIS 3279 TOM certification (in orange only), the model is also approved for use in British railway work.
When do you choose the Portwest B304 hi-vis sweatshirt instead of a hi-vis jacket or vest?
The B304 sweatshirt is the right choice when you need Class 3 visibility but prefer a soft, flexible garment that is easier to move in than a zip-up jacket or a stiffer vest.
Unlike a standard hi-vis vest, this model also provides some warmth due to the woven 65% polyester and 35% cotton material of 300 g/m². The hood adds extra protection in rain or wind without the need for a separate head covering. For heavy rain conditions or extreme cold, a waterproof hi-vis jacket remains the better choice, but as a mid-layer or for milder days, this sweatshirt is practical and comfortable.
The garment is washable up to 40°C and resistant to a maximum of 50 washes, which keeps the lifespan and visibility performance up to standard.
