My photos show I'm doing my masterwork with it. It doesn't feel like a plastic sheet, it has protected my mattress so far, and when covered by another sheet it's invisible. I use it for my bed in the dungeon, but I've also used it on my couch at home to protect it from my animals and on my bed as a mattress pad. It costs money. I've bought several and had no problems. As mentioned in other reviews, it doesn't suck up. It kind of collects liquid, but it's not a terrible wet stain. For water sports I would just keep it under or over your regular sheet for fun without the mess.
