Seamless boys’ thermal underwear 4F Junior with long sleeves has been designed as the first clothing layer for skiing and other winter activities. The fitted construction sits comfortably directly against the body and allows a T-shirt to be worn comfortably under a sweatshirt, fleece or jacket.

4FSkin technology supports a close fit of the material to the body and provides a second-skin effect. The flexible construction does not restrict freedom of movement, making it suitable for activities that require a high degree of mobility.

The seamless construction reduces the number of protruding material joins, helping to minimise the risk of chafing and irritation during extended wear. The quick-drying finish supports comfort during exertion and helps remove moisture from the material more efficiently.

Raglan sleeves increase freedom of movement in the arms, while the crew neck provides a classic and comfortable finish. The model is a functional top for boys’ thermal underwear intended to be worn as a first layer.
