When people first started surfing leashes weren't even a thing, and they were referred to as "kook cords." Now you're more of a kook if your surfing without one! Maintain your board connection with the DaKine Longboard Kainui 9' Calf Leash. This ultra durable cord is perfect for longboards thanks to its length obviously but also because of a slightly larger cuff. There's even space for your key in a small cuff pocket. Test and thrash the Kainui Calf Leash because it will hold up.
