Used in Motorcycle storage area in shadow of building but exposed to wind, rain and sunlight. It is hung over the Main's Cover for protection and blindfold. After two years, it was replaced because of fading and rips. I would have liked it to have lasted a little longer, but I think the conditions of use are on the severe side, so I guess it can't be helped. Thanks to this, the Main Cover is good with no noticeable deterioration.
