Hiya, Carrieanne,

I believe Emmaljunga means the parent to use the single carrycot (ad then seat) rain cover for the arts, otherwise I did not find the original double rain cover for this. Apart from that, you can always use a universal rain cover for double prams, like this one on Amazon, for example. Be sure to just search for a 'double stroller rain cover' and pick one that is on a similar type of stroller, and you'll be fine. Or better yet, go visit any larger baby store and try a few out (or let them advise you from what they have in offer).
