Our Leashes were tested by our entire SUPSmart Team as we selected the perfect size leashes. Why a 9' Leash? We discovered 10' caused about a foot of drag in the water which slows the paddler down and forces use of extra energy. Meanwhile, 8' or less did not allow us to move around the board freely making the 9' Coil the perfect size. Leash includes a hidden pocket for a Key. Next we decided that Paddlers should be able to match the leash to popular colors, so we have 17 colors including transparent and inner white. Please contact for colors not listed here.
