Indoor Car Covers: Difference Between 3 Fabrics

BY Thomas S.

You park your car in your garage for a reason – you want to keep it in pristine condition for years to come. But, just because it’s safe from exposure to the elements doesn’t mean it’s safe from everything. From moisture and condensation to dust and mildew, there’s plenty of pitfalls that can still befall your ride if you park it indoors.

What’s the best way to combat those dangers, you ask? It’s simple – an indoor car cover made from a specially designed fabric provides the protection you’re looking for. With so many options in our extensive selection, however, it’s hard enough to choose the right cover, let alone the right fabric.

Fortunately for you, this article should make your shopping experience easy. Familiarize yourself with this resource for helpful hints, advice and tips on selecting the best indoor car cover fabric for your vehicle.



If dust is your main concern, then maybe this flannel-esque car cover fabric may be the one for you. Designed with a four-layer, non-woven composite, each dustop cover is ultrasonically laminated to provide a high level of dust-protection that remains breathable and soft against your fine paint finish. As such, dustop covers are also lighter and easier to handle than covers made from conventional woven fabrics.

  • The top two layers consist of a polypropylene/polyethylene composite. These layers allow the cover to combine the best attributes of each polymer – the softness of polyethylene and the superior strength and stability of polypropylene.
  • When compared to your more common woven, single-layer fabric car covers, the melt-blown polypropylene layer of a dustop cover provides a stronger barrier to dust, dirt and grime.
  • With a polypropylene/polyethylene inner layer (the same materials some of the softest baby diapers are made of), dustop covers are the perfect way to pamper and preserve your baby’s paintjob.


Tan Flannel

Tan flannel covers caress your exterior and are sure to keep it looking great. Fabricated from a durable poly-cotton blend, they’re uniquely suited for indoor use.

  • The flannel underside makes for a soft, napped finish.
  • 50% heavier than entry-level car cover fabrics to wear better over longer periods of time.
  • Breathable enough to allow moisture to evaporate and not trap heat between the cover.
  • Water-resistant for superior moisture-repelling capabilities.
  • Specially treated to resist rot and mildew.



Best for cars that aren’t daily drivers, a form-fit car cover combines a body-hugging fit with a soft-to-the-touch inner layer. The outer layer is made from a woven polyester with Lycra/Spandex added to the yarn to create stretch and memory. That stretch and memory ensures the body-hugging fit and that the cover will keep its shape through years of storage.

  • Inside fibers are 100% cotton terry loop, sheared to a fleece-like finish resulting in 7.4 oz per/sq yd for a smooth feel.
  • Provides additional ding-, dent- and scratch-protection if you’re parked in a crowded garage.
  • Form-fitting fabric is also highly breathable to prevent vapor and heat from becoming trapped in between the cover and the car, which can lead to harmful mildew forming.
