Have used their covers for years, also in the CA sun like OCD. They fit nice but should be tied underneath, from wind and theft. The grey one I have been using had a five year warrenty, started wearing out after four years in the sun and they sent me a new one when I produced my sales receipt and sent them the cover.
I guess if they keep wearing out after four years and keep their same warrenty I will never have to buy another cover?
