Bike covers

I'm using a Sealey cover, available here (and other places):

Medium fits a Commando comfortably. I've had one for a couple of years now and it's as good as ever, however I use it to cover the bike under a lean-to car port, not fully out in the open.

(I have no idea why a seller called vw-parts-international is selling bike covers.)
