No, you don't need gloves to longboard. However, some people prefer to wear gloves while longboarding for a variety of reasons. Wearing gloves can help improve your grip on the board, protect your hands from getting scraped up if you fall, and keep your hands warm in colder weather. If you decide to wear gloves while longboarding, be sure to choose a pair that is comfortable and won't interfere with your ability to grip the board properly.
