Multi-standard polo shirts and T-shirts combine several protective features in a single base layer, such as flame resistance, anti-static and high visibility. This keeps you protected when you take off your jacket, and the shirt itself does not pose an additional risk when worn under your jacket.
This collection features around ten Portwest models from the Modaflame range: short- or long-sleeved polo shirts and T-shirts in high-visibility colours and dark versions. The specific standards met by each shirt are listed with every product.
