As I suspected the cover no longer has any water resistant qualities. I tested it under the shower, just to be sure, saturated immediately. This is to be expected with such an old pieceofequipment. However, the waterproofing can be re-established by simple application of Scotchgard (Outdoor sun & water shell), or any other waterproofing product, by spraying it on the outside. Like all waterproof material these days it will need regular maintenance.
Otherwise, excellent delivery time, along with the other products I purchased.
