The 4F women's thermal underwear (top) is made of high-quality synthetic materials that are soft to the touch and provide thermal comfort throughout the day. The microfleece lining, made with 4FWarm technology, adds extra warmth. This sweatshirt is perfect as a second layer under ski wear, but also works well for everyday wear. The extended back provides additional coverage and a soft stand-up collar protects the neck, allowing you to enjoy the slopes without worrying about getting cold.
