Children's 4F thermal underwear for winter - thermal comfort and fit

4F thermal underwear for children has been designed with winter activities in mind, when effective protection against the cold and comfort of wearing all day long are important.

The 4FWarm technology helps maintain a stable body temperature, reducing chilling during movement. The brushed interior of the knit fabric comfortably hugs the skin and acts as a warming layer.

The collared neckline with perforations promotes thermal comfort around the neck while improving air circulation. It's a practical solution for intense winter days.

The slim fit fits snugly to the child's figure and works seamlessly with subsequent layers of clothing without restricting freedom of movement.
