4F women's fleece thermal underwear is a lightweight long-sleeved top designed to be worn as a second clothing layer when skiing, winter trekking and taking part in other activities in cold conditions. The thin fleece knit, slim fit and high stand-up collar provide thermal comfort and freedom of movement. This model is a practical option in the category of women's fleece and brushed thermal underwear, suitable as a warming layer under a ski or trekking jacket.

The main material is made of 94% polyester and 6% elastane. Polyester provides the knit with lightness and functional properties, while the elastane content increases its stretch, allowing it to comfortably adapt to the body's movements. The thin, soft and breathable fleece structure provides thermal insulation without excessively increasing the volume of the clothing. The 4FWarm technology helps retain the heat generated by the body and helps limit its loss during activities in lower temperatures.

The slim fit sits comfortably on the body, making it easier to wear additional clothing layers without excessive material build-up. The high stand-up collar additionally protects the neck from cold air, increasing comfort when spending time outdoors. The lightweight construction provides freedom of movement during activities on the slopes and mountain hikes. The 4F women's thermal underwear top combines the thermal insulation properties of fleece with a functional fit designed for layering.
