SS stands for Super Stable, and that makes this inflatable Airhead SUP perfect for beginners, intermediates, and larger riders. Great for fishing, yoga, and 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. Features drop-stitch rugged construction, anti-skid EVA pad, and four D-rings for attaching gear. A mesh backpack, high pressure hand pump, pressure gauge, valve wrench, and repair kit are included. 15 PSI rating. 10'8"L x 38"W x 6"H.
