When a 0.10 score can make all the difference in your surfing career, it is essential that every single piece of your equipment is optimized to the highest performance extent. A competition leash was designed for smaller wave, high performance surfing. They are only 5-6mm thick, and this is because when performing big turns or airs, the leash creates a drag that can affect even the most minuscule of movements, so less leash equals less drag!
It's true, you don't have to be competing to appreciate the thin and unnoticeable nature of a competition leash, and a lot of good surfers go for this when enjoying playful and small conditions.
