Firstly I agree with previous reviews, the colour is lighter than shown but not unpleasantly.
The shape is different to the picture also in that it's almost a `ball' at the bottom with a cylinder on top, giving a more tailored fit. This isn't a problem, the elastic at the bottom works well to keep it on in a wind but makes it a more tricky to put on than my previous cover.
This was bought as a replacement for the previous `La Hacienda' green cover which was rubbish. The plastic coating seemed to `set' and become stiff, which in turn meant the cover became brittle. I think this is due to the sun (UV affecting the structure of the plastic), which is another plus point of this cover. Another reviewer seemed a bit confused about the `sun proofing' but I assume and hope that the sun proofing means this cover won't become brittle.
Update: It certainly is waterproof with the rain beading on the fabric nicely. One downside is the water collects at the seams.
