The doors are made of a canvas type material. They have been in severe rain storms, washed quite a few times, and rain still doesn't saturate them. The plastic is pretty tuff. My doors are attached with snaps into the body. The front doors zip around three sides and fold back to the b billar. The rear doors unsnap and roll and attach at the b billar also. I can make some doors that you can unzip the window and also unzip the whole door. The front doors with one zipper for material and labor is $150 each, the rear doors with no zipper are $125 each, and the rear hatch with no zipper or tire bumpout is $100.
