Replacement cover for the backrest of a Skywave Type S. A tacker is required for replacement. I purchased a cover from TOKUTOYO, but since I don't use the original backrest, this is an unused item. The manufacturer's description is as follows: The fabric is black (black) leather-like synthetic leather. Diamond-cut stitching on the surface. Thin sponge is inserted and sewn on the back of the seat surface to create a crisp look. "The surface is waterproof, but please note that some water may seep in from the seams of the seat if used in wet conditions for a long time." However, it's better to assume it's not waterproof, as the seat absorbs a considerable amount of water in the rain. I do not know if it fits different model vehicles, so please make your own judgment. There is a large margin on the back, so cut off the excess after tacking. Everything in the photos is included.
