If you're looking for a car cover to protect your vehicle from the elements, there are a few things you'll need to consider. The fabric type, the cover's weight, and the cover's size are all important factors to keep in mind. There are a few different types of fabric to choose from, including polyester and PVC. Polyester is a stronger fabric & a good choice for areas with high wind speeds. PVC is a more lightweight fabric & a good choice for areas with milder weather conditions.
