Product Benefits

Hi-Vis Class 3, Weather Protection
and Unique Safety Details

Hi-Vis Class 3

Certified according to EN ISO 20471 Class 3 – the highest hi-vis level for maximum visibility day and night. Wide reflective strips around torso, shoulders, and sleeves for all-round safe visibility.

Taped Seams

A rare feature in sweatshirts: taped seams offer additional protection against biological hazards – ideal for use in hygiene-sensitive areas or when in contact with liquids.

UPF 40+ UV Protection

The fabric is classified with UPF 40+ and blocks 98% of UV rays – reliable sun protection for all outdoor activities, even during long shifts in direct sunlight.

Compliant after 50 Washes

The EN ISO 20471 certification remains fully intact after 50 washes – tested durability throughout the garment's lifespan without loss of hi-vis performance.

The Mid-Layer Solution

Too cold for a t-shirt, too warm for a jacket – the B303 fills this gap perfectly. The generous cut also provides space for a warming base layer in very cold conditions.

Warmth & Comfort

Knitted cuffs with brushed inside for extra warmth. Ribbed knitted cuffs on sleeves and hem, plus a fully elastic waistband, ensure a perfect fit and all-day wearing comfort.


Technical Data

Material &
Specification

The Portwest B303 Hi-Vis Sweatshirt combines certified EN ISO 20471 Class 3 hi-vis protection, high wearing comfort, and robust construction for continuous professional use. The 300 g/m² heavy sweatshirt offers an ideal combination of warmth, breathability, and durability – perfect for changing weather conditions outdoors.

Thanks to UPF 40+ UV protection, the material reliably protects against harmful solar radiation and is ideal for long outdoor deployments. The reflective hi-vis strips ensure maximum visibility day and night and remain compliant even after numerous washes.

Particularly suitable for railway use (RIS-compliant operational environment)

The B303 is also suitable for work in railway and track areas, as it meets the requirements for highly visible protective clothing and in many cases complies with RIS-3279-TOM compliant workwear (in orange version only). This makes it ideal for activities in track construction, railway service, maintenance, and infrastructure work along the rail network.

The robust construction with durable seams ensures high resilience in daily use, while the comfortable cut guarantees freedom of movement even during long shifts.

Frequently Asked Questions

FAQ

What do welded seams mean for the B303?
Welded seams are joined by heat or ultrasound instead of being sewn, which eliminates needle holes. This prevents potential entry points for liquids or microorganisms, offering additional protection against biological hazards – a rare feature in high-visibility sweatshirts in this price range.
Why is the B303 designed as a "mid-layer"?
The B303 fills the common gap between a T-shirt and a jacket: for temperatures where a T-shirt would be too cold and a jacket too warm. The generous cut also provides space for a warming base layer underneath, so the B303 also functions as a mid-layer in very cold conditions.
What does "certified after 50 washes" mean?
The EN ISO 20471 standard stipulates that high-visibility clothing must meet the required minimum visibility values even after repeated washing. The B303 has been tested after 50 standard washes and still complies with the standard values – this guarantees safety throughout the entire lifespan of the garment.
Does the RIS 3279-TOM railway standard apply to both colors?
No – railway standard RIS 3279-TOM applies exclusively to the orange version of the B303. The yellow version is not certified for this specific application. Those who wish to use the B303 in railway operations must absolutely choose the orange variant.
How should the B303 be washed?
Machine wash according to manufacturer's instructions. Do not use bleach or fabric softeners – these can impair the luminosity of the high-visibility color and the reflective strips, and damage the welded seams in the long term. With correct care, all protective properties will be permanently maintained.
Are bulk discounts and company printing available?
Yes. For orders of 10 pieces or more, we offer tiered volume discounts. Company printing and embroidery are also available on request. Contact us directly.
