The women’s seamless thermal underwear – top by 4F has been designed as a base layer for skiing and other winter activities. The slim fit sits close to the body, while the standard hip length allows the top to be worn comfortably directly under additional clothing layers.

4FSkin technology supports a close fit of the fabric to the body, providing a second-skin effect. The seamless construction reduces the number of protruding fabric joins and helps minimise the risk of chafing during movement and extended wear.

The quick-drying finish supports moisture wicking during activity, while specially positioned ventilation zones help maintain proper air circulation and thermal comfort. As a result, the long-sleeve top works well as a base layer under ski or snowboard clothing.

Raglan sleeves increase freedom of movement in the arms, while the crew neck sits comfortably under additional clothing layers. The elastic knit made of polyamide, elastane and polyester adapts to body movements while retaining the functional character of first-layer clothing.
