Like all clothing, swimbriefs don't like it if you treat them badly. They don't appreciate the contact with sun screen or with oil. We advice you to wash your swimbriefs with clear water directly after you went for a swim in the sea or in the swimming pool. Afterwards, the best is to wash your swimbriefs by hand and with cold water, in any case at a maximum of 30°C. Avoid dryers and dont iron the your new favorite. Take care - like this you will enjoy the swimbriefs for a longer time.
