The rich aqua blue color of these covers may remind you of swimming in the shallow ocean waters of Hawaii. That would be nice. Anyway, the color is actually called Azure and these covers are made from PE (polyethylene) plastic. Finished with a smooth sand like finish they are soft to the touch, water proof and durable. We stock Azure sand covers in thicknesses ranging from 16-55 gauge and offer the covers in a large variety of sizes. We will even add windows or punching if you would like. All of this talk of the beach might make you want to go swimming. Just don't forget to order your covers first.
