Keep Jack Frost at bay with Trespass' range of thermal underwear for girls. No one wants to feel the chill on the ski slopes, so add our thermal sets to your kid's layer system. Thermals work as the perfect base layer, as they trap in body heat and feel great against the skin. Not got a skiing trip planned? No problem! Wear our thermals here for added warmth during the winter.
