SS stands for "Super Stable", and that's just what this very special inflatable SUP is. Beginners, intermediates and larger riders love the SS's unparalleled stability. Great for fishing, yoga & more! Experts, especially extreme whitewater paddlers, appreciate the stiffness, lower standing area, tapered rails and aggressive nose for punching through waves. SS remains stable even when way up on edge. Three fins, with removable center fin, ensure straight tracking. A mesh backpack, high pressure hand pump, pressure gauge, valve wrench and repair kit are included. If you are looking for recommended inflatable paddle boards the SS is a great one to choose!
