Sunbrella works great, though it obviously won't be as durable as naugahyde (which i think is vinyl). I use something called weathermax which I got off e-bay (was labelled on e-bay as Surlast, which it clearly isn't) and it works well also even though it is lighter than sunbrella. You do have to pick the correct color sunbrella though. Seems as though none of the colors really work as well as their standard pacific blue in terms of showing dirt, etc
