I have used OMNI bags for over 20 years. They are a heavy vinyal tap materal with a zipper on three sides. You drive or roll your car over the bottom , fip it over your car and zip it up. I do use a cotton car cover uner the OMNI bag. WHY???? A car cover covers the top of you car, the under side is unprotected from moisture and inter-action with the cement floor. Also in spring when tem. varies you get condensation on all the underside , under the car cover and engine bay. I use a box of oil dry or cat litter under the car and when I take the car out in the spring it looks just like the day I put it in the bag. MOISTURE is you big problem, connector, electrical, critters ,etc. The OMNI bag solves the mousiture problem and does not let anything in.
