The sides, front, and back all roll up and have straps that hold them up. Great for on the trail visibility. You can order it with or without side windows. I got it without since I don't want prying eyes looking at my junk in the bed. It does have the back window and it has not fogged up at all... I drove all the way back from Moab with the floor jack handle pressing against the window and there are no scratches. I love the thing /forums/images/graemlins/thumb.gif
