These are size "small" neoprene cockpit skirts. I think "small" means that this fits a cockpit that is 18 inches wide and 31 to 33 inches long. If these do not fit your kayak you can return them for a refund. One is just a cover and it is Snap Dragon brand, and the other is a sprayskirt and it is Tahe Marine brand. The sprayskirt has never been used, and the cover is in excellent condition.
