Prestige Covers will protect against the sun, rain, dust, bird lime, tree sap, pollutants and heat. They are made from triple layer SFS materials that beads water on contact affording maximum resistance to rainfall and snow. The covers also have tough interlocking seams but are also soft and lightweight so they do not scratch (none of this applies to Stanetta). Other features include hold down straps, elasticated hems and a free storage bag.
