        Functional underwear is specially designed base layer clothing made from technical materials that perfectly adapt to the needs of active people. Our functional underwear for women and men supports the body's temperature regulation, effectively wicks away moisture, and ensures you feel completely comfortable even during intense activity – no matter the weather.

        Functional Underwear for an Active Lifestyle

        For anyone who exercises regularly or is often on the move in everyday life, functional underwear for men and women is a smart investment. Especially during the colder months, it protects against cooling down without compromising on comfort. Whether you're running, cycling, skiing, or simply active throughout the day – functional underwear ensures that sweat is drawn away from the skin and evaporates quickly. This keeps your body dry and prevents it from getting cold. Especially in changing temperatures or during intense physical activity, the right functional underwear makes a real difference.

        Iconic Boxer Shorts for Active Days

        These sporty boxer shorts combine style and function: the soft Soft Touch cotton fabric makes them the perfect functional underwear for sports and everyday life. And with the iconic logo on the elastic waistband, you wear the NAKED lifestyle directly on your skin.

        Frequently asked questions about functional underwear

        Here you’ll find answers to frequently asked questions about functional underwear.

        Functional underwear is made from materials that actively wick sweat away from the skin and regulate body temperature. Traditional cotton underwear retains moisture, which can lead to discomfort and rapid cooling. Functional underwear, on the other hand, keeps you dry and ensures a pleasant climate against the skin – even during intense physical activity.

        Many functional underwear models are so comfortable that they’re perfect for everyday wear – for example, as an extra layer on cool days or simply when you value a dry and comfortable feeling throughout the day.

        In winter, functional underwear keeps you especially warm, while in summer, it helps cool you down. The materials regulate temperature and wick away sweat – so you stay comfortably dry in every season.
