Strength and length are keys to a great SUP Surfing Leash.
Kāohi offers both in a variety of styles, with the added advantage of the Kāohi Grip: 
- Kāohi Double Coil

Find your style here!

EXTRAS:
Many SUP Surfers prefer to attach their leash at the waist to help keep it out of the way.
Consider the Kāohi Black Belt Waist Belt if that's you.

The Paddle Belt is a leash for your Paddle... use it when you need your hands free, not when you are actively Paddling.
