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

The main material is made of 100% polyester, which is lightweight, durable and easy to care for. The soft, thin fleece knit supports thermal insulation without adding excessive bulk to the clothing. The applied 4FWarm technology helps retain the heat generated by the body and limit heat loss during activity in lower temperatures. The lightweight and breathable material structure promotes comfort when worn under additional clothing layers.

The slim fit sits comfortably against the body, making it easier to wear additional layers without excessive material build-up. The high stand-up collar with a short 1/3-length zip protects the neck area from the cold, while the adjustable opening allows the thermal comfort to be adapted to the intensity of the effort. The long-sleeved construction provides freedom of movement during activities on the slopes and mountain hikes. This women's thermal underwear top from 4F combines the insulating properties of fleece with a functional cut designed for layering.
