The LD600+ are silk liners designed by the brand Racer to provide you with comfort and warmth during all your winter activities, such as snowshoeing, alpine skiing, or hiking. In these cases, the LD600+ liners are worn under ski gloves and offer an extra layer of gentle warmth. Alternatively, these technical liners can be worn on their own during your running and trail sessions, and even in everyday life when the winter cold hits the city.
