Ride Engine makes surfboard bags designed to protect your board whether you're just driving to the beach or flying across the world. Their bags often feature 5 mm closed-cell foam padding (or more in travel models) to cushion top and bottom sides of the board. They also use UV and weather-resistant outer materials (for example, the “Solar Shield” line uses a tarpaulin shell to block sun damage) which helps keep your board from heating up or getting warped on a hot car roof.
