Women’s Fleece Thermal Underwear Top 4F 4FRAW25UFLEF080-20S

The 4F women’s fleece thermal underwear is a lightweight long-sleeve top designed to be worn as a second clothing layer while skiing, winter trekking and during other activities in cold conditions. The thin fleece fabric, slim fit and high stand-up collar provide warmth and comfort during movement. This model is a practical choice 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 a lightweight feel and functional properties, while the elastane content increases the fabric’s stretch, allowing it to comfortably adapt to body movements. The thin, soft and breathable fleece structure provides thermal insulation without excessively increasing the garment’s bulk. The applied 4FWarm technology supports the retention of body-generated heat and helps limit heat loss during activities in lower temperatures.

The slim fit sits comfortably on the body and makes it easier to wear additional clothing layers without excessive fabric build-up. The high stand-up collar provides additional protection for the neck against cold air, increasing comfort when outdoors. The lightweight construction ensures freedom of movement during activities on the slopes and mountain hikes. This women’s thermal underwear top by 4F combines the thermal insulation properties of fleece with a functional cut designed for layering.
