pm124: To confirm, the Birdy light dust cover fits the Dahon Curve D3. I purchased mine from Don at http://blackdogbicycles.com/birdyfoldingtravelbike.html and it arrived w/in 2 days. Don was a great person to do business with and responded to my emails immediately. He measured the cover prior to shipping to ensure a proper fit.

The cover is colored silver on the exterior and black on the inside. It is more durable than the nylon Dahon cover but perhaps less packable. It does come with a drawstring and a cut-out in the top so that you can reach in and grab onto the bike with the cover on.

Of course it says Birdy on it but I didn't mind.
