Seat pads and back bands are common gear for a surf kayak. While a standard sit-on-top kayak seat can be used for a surf kayak a back band is often considered best, used in combination with a self-adhesive seat. A wave ski will typically have just a seat pad, seat belt and foot straps. Visit the knee straps section of our Sit-on-top Gear department for a full range of leashes.
