travel bag for Inglesina Twin Savvy?

[ccab]

I'm travelling at the end of the month and want to bring my Twin Swift but don't want it to get ruined by the airline baggage handlers. I can either gate check or check with my other luggage. Dimensions when folded are 46"H, 18"W, and 10"D (or so it says online). I've seen a couple double stroller covers, including a Maclaren one, but it says that it's approx. 42"H (4 inches shorter than mine).

Any suggestions would be much appreciated!
