Description With EN 20471 certification, the Zip-Neck Shirt ideally suited for work in road construction, air rescue or other areas where extremely good visibility is important. The StretchAIR® technology ensures maximum wear comfort with unrestricted freedom of movement even for the Poly Zip Neck Shirt. It remains colour-fast at 100% even after hundreds of wash cycles. 37.5 stands for the constant body temperature of 37.5 °C, even during peak physical performance. The fabric immediately wicks away excess moisture and heat, keeping body temperature constant. Odour particles are trapped and only released during washing. The material is odourless.
