A top-secret prototype. The Billabong V1 Wetsuit is now in limited production and being distributed to the world’s top big wave riders, but it’s not yet being sold to the general public. So what’s so special about it? It’s inflatable. Yes, you read that right. It’s inflatable. The Billabong V1, aka the Inflatable Big Wave wetsuit, has a built-in bladder that inflates when the wearer, like a surfer, pulls the inflation cord. Developed through a partnership between Billabong (the wetsuit folks), Mustang Survival (the safety gear folks) and Shane Dorian (the surfer who thought of it), this may be the next big thing in water gear.
