Women’s seamless thermal base layer – bottoms by 4F has been designed as the first layer of clothing for skiing and other winter activities. The slim fit sits close to the body, while the high waist and full-length legs ensure a comfortable fit under additional layers of clothing.

The 4FSkin technology ensures that the fabric closely follows the body, creating a second-skin effect. The seamless construction reduces the number of protruding fabric seams, helping to minimise the risk of chafing during prolonged wear.

The quick-drying finish supports moisture wicking during physical activity, while strategically placed ventilation zones promote air circulation and help maintain comfort during activity. This makes the model well suited as a base layer under ski or snowboard trousers.

The stretchy polyamide and elastane knit fabric adapts to the body’s movements without restricting freedom of movement. The model is designed to be worn directly against the skin as a first layer for skiing, snowboarding, winter hiking and other activities in cold conditions.
