I didn't feel like shelling out $100 bucks for the Mopar window bag, so here is what I came up with for $13. Buy a fold-up camp chair with the carrying bag. Get some sort of thin fleece (I got a blanket from Ikea for $3) and cut it to the shape of the windows. Lay the fleece on both sides of the windows, roll the windows up together and stick them in the camp chair bag. Voila, you're done. The fleece prevents the windows from scratching one another. At the end of the day, you have a good storage solution for the windows and a bush chair. Win win!
