The best Miata car cover for most owners is a model-specific cover with wind straps, such as the Kayme six-layer or the Favoto with a driver-side zipper. Universal coupe covers fit looser, so measure first: a current ND Miata is about 154 inches long. Parking outdoors? Choose layers and straps. Parking indoors? A soft, breathable cover is enough.

More Details on Our Top Picks
Waterproof All-Weather Car Cover for Coupe Roadsters
This is a universal cover, not a Miata-specific one. The listing says it fits coupes and cabriolets up to 166 inches and names the MX-5, Z3, Z4 and S2000. A current ND Miata is about 154 inches long, so it falls inside that range.
Expect a looser fit than a custom cover. The listing describes a polyester taffeta shell, three windproof straps, elastic edges, six reflective strips and a storage bag. Measure your car and read the size note before you order.
- Fit:Universal, up to 166 in (per listing)
- Material:Polyester taffeta (per listing)
- Wind security:3 straps plus elastic edges
- Reflective strips:6
- Zipper:Not listed
- Storage bag:Included
Pros
- Listing names the MX-5 among its fits
- Covers a wide size range
- Elastic edges plus 3 straps
Limitations
- Universal cut is looser than a custom cover
- No access zipper listed
- Weather claims come from the seller description only
Mazda MX-5 Miata Outdoor Car Cover with Zipper
A model-specific cover that also has a zipper (it is in the product name). The listing says it is made for 1989 to 2025 Miatas and describes 420D oxford fabric with a PVC lining, a 3000 mm hydrostatic rating, double-stitched seams, an elastic hem, four tire straps, reflective strips and a storage bag.
If you want a custom cut plus access without removing the whole cover, compare this one with the Favoto below. Confirm your year and body style (soft top or RF) on the listing before buying.
- Fit:Model-specific, 1989-2025 (per listing)
- Fabric:420D oxford with PVC lining (per listing)
- Water rating:3000 mm hydrostatic (per listing)

- Storage bag:Included
Pros

- Zipper named in the product title
- Four tire straps for wind
Limitations
- Year and RF fit should be confirmed on the listing
- Coated waterproof fabric can trap moisture if the car is wet when covered
Favoto Waterproof Car Cover for Mazda MX-5 Miata
Favoto sells a Miata-specific cover with a driver-side zipper, so you can reach the cabin without pulling the whole cover off. The listing describes Oxford fabric, double stitching, an elastic hem, three adjustable straps, four reflective strips and a storage bag.
The listing also says it does not suit cars with a fixed antenna and that seam leakage is possible. Treat it as a good everyday cover rather than a fully sealed one.
- Fit:Model-specific for MX-5 (per listing)
- Fabric:Oxford (per listing)
- Wind security:Elastic hem plus 3 adjustable straps
- Reflective strips:4
- Zipper:Driver-side
- Storage bag:Included
Pros

Limitations
- Not for cars with a fixed antenna (per listing)
- Seller notes seam leakage is possible
Kayme 6-Layer Car Cover for Mazda Miata MX-5
Kayme’s six-layer cover is the heaviest-duty option here for outdoor parking. The listing describes a PE and PEVA waterproof shell, a reflective aluminum layer for UV, a soft cotton lining against the paint, three windproof straps, four reflective stripes, a storage bag and 12-month support.
The listing gives a 1990 to 2025 fit, while the other custom covers say 1989 to 2025. If you own a 1989 car, check with the seller first.
- Fit:Model-specific, 1990-2025 (per listing)
- Construction:6 layers: PE, PEVA, aluminum, cotton (per listing)
- Wind security:3 straps
- Reflective stripes:4
- Zipper:Not listed
- Storage bag:Included
Pros

Limitations
- No access zipper listed
- More layers usually means a heavier, bulkier cover to fold
- Year range starts at 1990
Universal Waterproof Car Cover for Sports Coupes
Another universal option, listed for cars up to 165 inches. The listing names the Miata/MX-5, BMW Z3, Honda S2000, Crossfire, Sky and Solstice. It describes polyester taffeta, three bottom straps plus a rear strap, four reflective strips and mirror protection.
It suits you if you want a simple cover and accept a looser fit than a model-specific one.

- Material:Polyester taffeta (per listing)

A model-specific six-layer cover with a door zipper. The listing says it fits 1989 to 2025 Miatas and describes PA coating, PE, aluminum and soft cotton layers, wheel straps, reflective strips and a storage bag.
It combines the custom cut and zipper access, but a six-layer cover is bulkier to handle. Confirm your year and body style on the listing.

- Construction:6 layers: PA coating, PE, aluminum, cotton (per listing)
- Wind security:Wheel straps

- Weather claims come from the seller description
Motor Trend Lightweight Breathable Car Cover (M 170″)
Motor Trend’s cover is a universal, lightweight option. The product name lists size M (170 in). A Miata is much shorter than that, so expect a loose fit, and check the size chart to see whether a smaller size suits better.
The listing describes it as water-resistant rather than waterproof, with a breathable fabric, soft lining, elastic hems and security grommets. It suits garage or carport use and light weather better than a stormy driveway.
- Fit:Universal, size M (170 in per product name)
- Weather:Water-resistant, breathable (per listing)
- Wind security:Elastic hems and grommets
- Zipper:Not listed
- Storage bag:Not listed
Pros
- Light and easy to handle
- Soft lining
- Breathable fabric
Limitations
- Size M is much longer than a Miata, so expect a loose fit
- Water-resistant only, not fully waterproof

Factors to Consider When Choosing a Miata Car Cover
Start with fit, then match the cover to where the car sleeps: outdoors, in a carport or in a garage.
Vehicle-Specific Fit
A model-specific cover follows the Miata’s shape, so there is less loose fabric to flap and rub the paint. Universal covers cost you some fit but can work if you measure first. Before ordering:
- Measure bumper to bumper, mirror to mirror and roof to ground. The 2024 ND is about 154.1 in long and 68.3 in wide without mirrors (per Edmunds); earlier generations are in the same range, but measure your own car.
- Check that the listing names your generation (NA, NB, NC or ND) and body style (soft top or RF).
- If your car has a fixed antenna, read the listing for any antenna note.
- Look at the size chart, not only the product title.
Weather Protection Level
For outdoor parking, look for a water-resistant or waterproof shell, UV protection and a lining that is soft against the paint. Waterproof ratings and layer counts are the seller’s claims, so treat them as a guide. A fully coated cover can trap moisture, so only cover a dry car and take the cover off now and then to let it air out. For garage use, a breathable cover is the safer choice. See our guide to all-weather car covers and car cover materials for more.
Material Durability
Oxford and polyester taffeta shells are common on these listings. Multi-layer covers add a reflective or waterproof film and a soft inner layer, but they are heavier to fold and store. Double-stitched seams are a useful sign, though the Favoto listing itself warns that seam leakage is possible.
Wind Security Features
Elastic hems and underbody straps stop a cover from ballooning. The covers above list between three and four straps, or wheel straps. Snug the straps but do not overtighten them, and re-check after a windy night.
Visibility And Access
A zipper lets you open the door without taking the whole cover off. The Favoto has a driver-side zipper, the Mazda MX-5 Outdoor Cover is named as having a zipper, and the custom-fit six-layer cover lists a door zipper. Reflective strips help you see a parked car at night. If you also own another roadster, see our convertible car cover guide and the Porsche Boxster cover guide.
Care and Safety Notes
- Wash and dry the car first; grit under a cover can scratch the paint.
- Let a hot car cool before covering it.
- Do not cover a wet car with a non-breathable cover.
- Follow the maker’s care label when cleaning the cover.
Frequently Asked Questions
How do I measure my Miata for the right cover size?
Measure bumper to bumper, mirror to mirror and roof to ground, then compare with the listing’s size chart. A 2024 ND Miata is about 154 inches long and 68 inches wide without mirrors, so a cover rated for 165 to 170 inches will be loose.
Can a car cover damage Miata paint?
It can, mostly when the car is dirty, when grit is trapped under the cover or when a loose cover flaps in the wind. Wash and dry the car, choose a soft lining and snug the straps to reduce the risk.
Should I buy a waterproof or a breathable Miata cover?
For outdoor parking, a waterproof or water-resistant cover is the usual choice, but only cover a dry car and air the cover out regularly because coated fabric can trap moisture. For a garage or carport, a breathable cover is usually enough.
Do I need a cover with a zipper?
It is optional but handy. A zipper lets you open the door or reach the cabin without removing the whole cover. On this page the Favoto and the six-layer custom-fit cover list zippers, and the Mazda MX-5 Outdoor Cover has one in its product name.
Will these covers fit a Miata RF or an older NA or NB?
The custom covers list roughly 1989 to 2025 fitment, but the listings do not all spell out body styles. Check that the Amazon listing names your generation and soft-top or RF body before buying, and ask the seller if it is unclear.
How often should I clean my Miata car cover?
There is no fixed schedule. Brush off debris regularly and wash the cover when it is visibly dirty, following the care label, because a dirty cover can scratch paint.
Conclusion
Pick a model-specific Miata car cover if you park outside and want a snug fit, and add a zipper if you open the car often. A universal coupe cover is a reasonable fallback if you measure first and accept a looser fit. Whichever you choose, confirm your year and body style on the listing and cover only a clean, dry car.
