Surf changing mats are a practical accessory for surfers who want to keep their gear clean, and their wetsuits protected during post-session changes. Made from durable, waterproof materials, these mats provide a clean surface to stand on while changing out of a wetsuit, preventing sand, dirt, and debris from sticking to your gear. Many designs double as a wetsuit bag, cinching up around the suit to keep wet gear contained and your car dry.
