The boys' functional sweatshirt from the 4F brand is a great accessory for winter and autumn activities. It is made of 190 g/m² single-sided brushed knitted fabric, which, in combination with 4F Warm technology, provides excellent thermal insulation while maintaining optimal comfort. The quick-drying finish helps wick away moisture and ensures a comfortable feeling during wear. Raglan sleeves promote freedom of movement and flat seams minimize the risk of skin irritation. In addition, the neckline and higher collar protect the neck from the cold. The 4F sweatshirt is ideal as a middle layer under a jacket or on its own for everyday wear and sports activities in colder weather.
