Men's thermal active T-shirt 4F M224 deep black 4FWAW25USEAM224 20S L/XL

Cold-weather training often forces a choice between warmth and freedom of movement—bulky layers restrict, while thin shirts leave you chilled. The 4F M224 thermoactive base layer eliminates that compromise. Made from a seamless 92% polyester / 8% elastane blend, it delivers a snug, athletic fit that moves with you, while 4F Dry technology actively wicks sweat away from the skin to keep you dry and comfortable through high-output sessions.

Who is it for

This men's long sleeve base layer is built for runners, winter sports enthusiasts, and multi-sport athletes who need reliable moisture management and thermal comfort without excess weight. Its deep black colour and clean round neck make it a versatile first layer under jerseys, jackets, or on its own during milder days.
