Car Cover Fabrics Tech Center


The light-weight WeatherShield car cover fabric employs a patented encapsulation process, originally developed for high-performance outdoor sportswear. The result is a car cover fabric that delivers maximum paint protection from the elements without the bulk, making it easier to handle and store.

The special encapsulation process surrounds woven polyester fabric with an ultra-thin film and a durable, breathable barrier. Traditional coatings and laminations only protect one side of the car cover fabric. The WeatherShield car cover fabric uses up to 40 computerized steps to place protective polymers inside the fabric to shed water, dust, bird droppings, tree sap and industrial pollutants.

WeatherShield fabricThe high-strength, polyester base fabric is naturally UV-resistant. To make the WeatherShield car cover more resistant to the rigors of sun exposure, UV inhibitors have been added to the polymers to help slow-down naturally-occurring degradation.

  • Weatherproof
    WeatherShield fabric sheds water as soon as it hits the car cover, leaving your vehicle dry.
  • Superior Dry Time
    Because WeatherShield car cover fabric sheds moisture, it has an absorption factor of only 2%, compared with up to 40% for standard woven and non-woven fabrics. That means, if the car cover has been sitting out in the rain, just shake it out and it's practically dry.
  • Breathable
    WeatherShield car cover fabric allows any heat or condensation that builds up under the cover to easily escape.
  • UV-resistant
    Special additives in the WeatherShield fabric prevent UV degradation while protecting your vehicle's paint and interior.
  • Dust-proof
    The WeatherShield car cover fabric's patented fiber encapsulation process prevents dust from filtering through the fabric.
  • Scratch-less
    Polymers provide a silky smooth finish to the fabric and provide superior paint protection. WeatherShield fabric has been tested at 1,000 cycles on abrasion wheels without scratching (surface must be clean and waxed).
  • Durable
    The encapsulation process is not affected by heat or cold and the process won't degrade over the life of the WeatherShield car cover fabric.
  • Easy Care
    Unlike non-woven fabrics, you can clean most car-size WeatherShield car covers in your home washer and dryer.
  • Packs small and Light
    The WeatherShield car cover packs into 1/4 to 1/2 the volume of standard multi-layer, non-woven fabrics.

WeatherShield HD

The WeatherShield HD (Heavy-Duty) car cover fabric was developed primarily for intense sun environments and long-term storage. The WeatherShield HD car cover fabric delivers UV-resistance, repels water, blocks dust, tree sap and bird droppings, and is still breathable to allow moisture and heat to escape from under the cover.

Even the best covers will eventually absorb waterThe base material for WeatherShield HD car cover is woven by Glen Raven Mills for CoverCraft using solution-dyed UV-resistant polyester fibers. Not only is the fabric solution dyed, the 300 denier construction is 40% heavier than the regular WeatherShield car cover fabric, doubling the tear and tensile strength.

WeatherShield HD fabricThis superior base fabric is then finished with the same patented encapsulation process used on the WeatherShield car cover fabric. Using up to 40 computer controlled proprietary processes, specially-formulated polymers are forced inside the car cover fabric to bond to each individual thread and fill the valleys between the woven fibers. These special polymers have amazing elasticity to block moisture and dirt, while still maintaining the breathability of the cover.

Who needs a WeatherShield HD car cover? People who live in intense sun climates and along the coast will benefit most from this car cover fabric. Plus, owners looking for the best cover for long-term storage.


CoverCraft's Noah car cover fabric actually stops water, yet it "breathes" to allow any trapped moisture, seam seepage or condensation to easily evaporate. The unique construction process results in a car cover with maximum all-weather protection. Noah car cover fabric delivers exceptional water resistance, dust resistance, UV resistance and breathability to expel moisture and/or heat. The Noah car cover fabric weighs a mere 4.45 oz./sq. yd., so it's still very easy to handle and fold. Noah is made in the US by Kimberly-Clark.

  • Protective Outer Layers
    The inner core of the Noah car cover fabric is polypropylene for strength, with a polyethylene wrap for softness. The silver-gray color was selected because of its heat-resistant properties. The fabric is also treated with UV inhibitors, making it safe for extended outdoor use.
  • Micro-Porous Middle Layer
    Noah fabricThe barrier layer is a proprietary breathable stretch-film developed exclusively for Kimberly-Clark. The film is stretched and subjected to a chemical process that creates microscopic holes smaller than droplets of water or dust, yet large enough to allow moisture vapor to escape from the Noah car cover.
  • Soft, Paint-Protecting Inner Layer
    A fabric made with polyethylene and nylon. This combination results in an exceptionally high strength-to-weight ratio, with the "soft touch" necessary for a car cover to protect today's water-based paint finishes.


Sunbrella fabricSunbrella car cover fabric delivers protection and years of service in intense sun areas, like the sun-belt, where UV rays will rapidly degrade the paint and interior. Because of the use of acrylic fibers, which are naturally UV-resistant, Sunbrella has long been the recognized leader in long-wearing marine fabrics for bimini tops, sail covers and deck enclosures, and car covers. Besides marine and automotive uses, Sunbrella fabric is used for commercial awnings due to its ability to providing UV blockage with a rich, woven finish. The acrylic fibers are solution-dyed before the fabric is woven to assure the color goes all the way through the fabric. Using a special finish process, the material is then softened for use as a car cover fabric.

  • Long Lasting Strength
    The Sunbrella car cover's acrylic fibers suffer minimal loss of strength from exposure to heat, moisture and UV.
  • Fade-resistant
    Colors are a result of pigments which are actually built into the fibers (solution dyed), instead of just dying the finished fabric.
  • Water-resistant
    Treated for moisture resistance (but remember, this car cover material is primarily for UV protection).
  • Rot- and Mildew-resistant
    Acrylic fibers resist growth that occurs in moist environments.

The Sunbrella car cover is available in Pacific Blue, Sky Blue, Cadet Gray, Jet Black, and Toast.
