Well, with the wind the other day the Clarke cover was as much use as a sheet of kitchen roll, it didn't hold itself on at all. So I've had to get another and wasn't going to get another Clarke, as its proved it isn't very weatherproof, I looked about and went for a halfords advanced cover this time, its breathable, the inside feels a bit softer and the best bit is it has 3 straps with buckles like on a kiddie seat on a shopping trolley, the 2 each end match up to the wheels and the middle is, er, in the middle. I've threaded the end ones through the wheel spokes so it cant migrate too much.
