Children's thermal underwear set 4F M248 deep black (4FJWAW25USEAM248)

Children’s 4F M248 deep black thermal underwear set is the perfect solution for active children who need clothing that provides comfort and support in various conditions. Thanks to the use of polyamide, polyester, and elastane, the underwear is highly flexible, allowing freedom of movement during play or sports. Additionally, these materials ensure quick drying, which is crucial during intense physical activity.

Advanced 4FSkin technology

The children’s 4F M248 deep black thermal underwear set is equipped with 4FSkin technology, which ensures an excellent fit to the body and provides all-day comfort. The seamless construction minimises the risk of chafing, significantly enhancing wearing comfort. The round neckline, long sleeves, and long legs further emphasise the functionality of this set.

Breathability and moisture-wicking

The children’s 4F M248 deep black thermal underwear set features high breathability, allowing effective moisture-wicking from the skin’s surface. This keeps the skin dry and the wearer feeling fresh and comfortable, even during intense physical activities. It is an ideal solution for children who spend a lot of time outdoors, regardless of the season.

Slim fit cut for a better fit

The slim fit cut of the children’s 4F M248 deep black thermal underwear set ensures an excellent fit to the body, resulting in greater comfort and efficiency while wearing. The elasticity of the materials allows easy adaptation to the body shape, which is especially important for children during periods of rapid growth. This means the underwear does not restrict movement and allows full freedom of activity.
