2014+ Dodge Promaster Premium slider Window (window behind passenger seat)

These window covers are made from ripstop nylon for the exterior, two thin layers of Thinsulate (3 season covers) on the inside of the cover, and the interior is another layer of ripstop nylon. I then sew horizontal lines with magnets sewn inside to fold up the window covers for storing them in the window when you are done with them. For example, the slider or the barn door window covers can be held in place by folding up the covers and attaching them with installed magnets. All of my covers can be upgraded to a 4 season cover which would add a layer of synthetic down between the two layers of Thinsulate making the cover about an inch thick and offering the most insulation on the market.
