Well, it all depends on what kind of clothing you are feeling comfortable with doing water sports. Most customers wear swimming shorts, bikinis or swimsuits. But also sportswear (similar to running) is popular with some customers. The clothes should be comfortable, but do not interfere unnecessarily when swimming, if you fall into the water. On colder days and just at the beginning of the season, when the waters are not so warm, many customers on-site at ALOHA-PIRATES borrow a wetsuit for the duration of the SUP course.
