Our premium quality cover is manufactured in high-grade 600D woven polyester 'Oxford' fabric and then further finished with a water-resistant PVC lining, forming a very durable material which has an excellent degree of thickness, in an attractive Gainsboro grey finish. An effective and efficient barrier against the elements like rain, sleet, frost and snow and even sunshine and harmful UV rays (could cause fading on paintwork). Also protects from dust and dirt, bird droppings and tree leaves and sap. The covered air vents reduce the risk of condensation build-up, stale air, and mould growth and also negate the risk of the cover being caught and 'ballooned' in gusts of wind. A strong nylon drawstring with a toggle and fastening clips secures the cover to your item and ensures a snug and impenetrable fit
