It is designed for professionals working outdoors or in cold environments at low temperatures. The combination of polyamide, polypropylene and elastane provides a close-fitting fit that does not restrict freedom of movement.\u003c\/p\u003e\u003ch2\u003eFor what type of work is the Portwest B171 Dynamic Air thermal underwear suitable?\u003c\/h2\u003e\u003cp\u003eThe Portwest B171 is suitable for outdoor work and cold working environments where body temperature needs to be maintained, such as in construction, logistics, agriculture or road management.\u003c\/p\u003e\u003cp\u003eAs a base layer, it is worn directly against the skin, under a mid-layer or outer jacket. Thanks to the moisture-wicking properties of polypropylene, the skin remains dry, even during physical exertion. This prevents cooling due to sweat and makes the underwear suitable for varying activity levels throughout the workday.\u003c\/p\u003e\u003ch2\u003eWhat does EN 14058 class 1 mean for this thermal underwear and when should you choose the B171?\u003c\/h2\u003e\u003cp\u003eEN 14058 is the European standard for garments that protect against cold environments. Class 1 represents a thermal resistance of 0.102 m².K\/W, which corresponds to a Clo value of 0.7. This is a light insulation value, intended as the first layer in a multi-layer clothing system.\u003c\/p\u003e\u003cp\u003eChoose the B171 when you need a thin, close-fitting base layer that fits under workwear without adding bulk. Unlike a heavier thermal layer, this model is also suitable for moderate cold or when the wearer moves a lot and excessive sweating is a risk.\u003c\/p\u003e\u003cp\u003eThe underwear is made of 245 g\/m² fabric and contains elastane for stretch.
