The STIGA Premium Indoor/Outdoor Table Cover is crafted of a highly durable, woven PE material for long-lasting use. This cover is made of the same durable material found in most high-quality automobile covers, offering exceptional protection for your table tennis table. The premium table cover utilizes elastic hems for precise adjustments and a snug fit on regulation size 9' x 5' ping pong tables that are folded in storage position. When storing outside, its phosphorous coating technology provides waterproof coating, prevents sun fading and rusting, and keeps dirt and leaves off the table. When storing indoors, the premium table cover prevents dust collection and protects the table from scratches and minor imperfections. Though this table cover can be used both indoors and outdoors, it should not be used to store an indoor table outside.
