Everything you need to know about our products, ordering, shipping, returns, and warranty — all in one place.

What types of covers do you sell?

We design protective covers for a variety of outdoor and storage applications including golf cart enclosures, bike transport covers, wire shelving unit covers, patio furniture covers, umbrella replacement canopies, and other equipment protection solutions.

Where is Formosa Covers located?

We are a family-owned business based in Irvine, California, and many of our products ship directly from our Southern California warehouse. Our support team is available Monday–Friday, 9AM–5PM PST.

Why should I use a protective cover?

Protective covers help extend the life of equipment and furniture by shielding them from sun damage, rain, dust, dirt, and environmental wear. A quality cover is one of the most cost-effective ways to protect your investment.

What materials are your covers made from?

Our covers are made from durable materials such as UV-treated polyester, canvas-style outdoor fabrics, reinforced stitching, and waterproof polyurethane coatings depending on the product. Each product page lists the specific materials used.

Are your covers waterproof?

Most of our covers are water-resistant or waterproof depending on the product design and material coating. Please check the individual product listing for specific water resistance details.

Are your covers UV resistant?

Yes. Many of our products use UV-treated fabrics that help reduce sun fading and material breakdown over time.

How long do outdoor covers last?

With proper care, high-quality outdoor covers can last several years depending on sun exposure and environmental conditions. Storing covers when not in use and cleaning them regularly will help extend their lifespan.

How do I clean my cover?

Most covers can be cleaned using mild soap, water, and a soft brush. Avoid harsh detergents, bleach, or abrasive pads as these can damage the fabric and reduce the water-resistant coating. Always allow the cover to fully dry before storing.

Can covers be used year round?

Yes. Many covers are designed for year-round protection against sun, rain, wind, and dust.

Golf Cart

Golf Cart Enclosures & Covers

Common questions about our golf cart enclosures and storage covers — sizing, compatibility, installation, and more.

What is a golf cart enclosure?

A golf cart enclosure is a protective cover that attaches to a golf cart roof and frame to provide protection from wind, rain, and cold weather while driving.

What is the difference between an enclosure and a storage cover?

An enclosure is designed for use while the golf cart is being driven — it attaches to the roof and frame to protect passengers from wind, rain, and cold weather. A storage cover is used when the cart is parked, protecting it from sun, dust, and the elements when not in use.

What golf cart brands do your enclosures fit?

Most enclosures are compatible with standard golf carts such as EZGO, Club Car, and Yamaha models. If you're unsure about compatibility, contact us with your cart's make, model, and year.

How do I measure my golf cart for an enclosure?

Measure the roof length, roof width, and height from the roof to the ground to ensure the enclosure will fit correctly. You can also reference our Golf Cart Sizing Chart for guidance.

Can I drive with the enclosure installed?

Yes. Golf cart enclosures are designed to be used while driving in cold or rainy weather. Storage covers are not intended for use while driving.

Do golf cart enclosures block wind?

Yes. Enclosures help block wind and improve comfort for passengers during colder conditions.

Are the windows clear?

Yes — most enclosures include clear PVC window panels to maintain full visibility while driving. Zippered doors can be opened or rolled up when you want the open-air feel. We also offer 3-sided enclosures on certain models, which omit the front windshield PVC panel entirely — a popular option for customers who prefer a more open front or simply don't need it.

Are the doors zippered?

Yes. Many enclosures feature zippered doors that can be opened or rolled up when needed for open-air driving.

How long does installation take?

Installation usually takes about 10 to 20 minutes depending on the enclosure design. No special tools are required for most models.

Do enclosures work in winter?

Yes. Enclosures help protect passengers from wind and cold weather while driving and are a popular choice for year-round golf cart use.

Can I leave the enclosure installed year round?

Yes, although some customers remove them during warmer months for open-air driving. Removing and storing the enclosure when not needed will help extend its lifespan.

Wire Shelving

Wire Shelving Unit Covers

Questions about our shelving covers — measuring, materials, door access, and the right style for your space.

What is a shelving unit cover?

A shelving unit cover is a protective enclosure designed to fit over wire racks to keep stored items clean and protected from dust, sunlight, and moisture.

Where can shelving covers be used?

Almost anywhere you have a wire rack that needs protection. Popular locations include garages, workshops, storage rooms, warehouses, home pantries, closets, and basements. They create a dust barrier, block sunlight, and help keep stored items clean and organized wherever they're placed. And the uses go beyond storage — our All PVC clear panel covers have even been used as a DIY indoor greenhouse, creating a warm, light-permeable enclosure for plants. The humidity retention and visibility make them surprisingly well-suited for it. The uses really are endless!

How do I measure a shelving unit for a cover?

Measure the height, width, and depth of the shelving rack and compare with the listed cover dimensions. If you need help finding the right fit, contact our team with your measurements.

Do shelving covers have doors?

Many shelving covers include zippered doors for easy access to stored items without needing to remove the entire cover.

Are shelving covers waterproof?

Most are water-resistant and designed for indoor or covered storage environments. They provide a good barrier against moisture but are not intended for fully outdoor, rain-exposed use.

What cover styles and materials are available?

We offer four main styles to suit different needs: All Fabric — maximum dust protection with a clean, solid look; PVC Front Panel — one clear front panel for easy visibility while keeping other sides covered; All PVC — fully transparent on all sides so you can see everything inside at a glance; and Dual Color — a main body color paired with a contrasting trim color for a more customized, polished look. Browse our shelving collection to see all available color and style combinations.

Can I remove the cover easily?

Yes. Shelving covers can be removed or reinstalled quickly when needed — no tools required.

Bike Covers

Bike Transport Covers

Questions about protecting your bikes during travel and storage with our bike rack covers.

What is a bike rack cover?

A bike rack cover protects bicycles mounted on a vehicle rack during travel, shielding them from rain, road debris, dust, and sun exposure.

What does a bike transport cover protect against?

It protects bikes from rain, road debris, dust, and sun exposure during vehicle transport. UV-resistant fabrics also help prevent fading and deterioration on both the cover and your bikes.

How many bikes can the cover hold?

We carry covers in small, medium, and large sizes to fit anywhere from 1 to 4 bikes depending on your rack setup. Choose the size that matches the number of bikes you typically transport — when in doubt, sizing up gives you more flexibility.

Can I drive on the highway with the cover installed?

Yes. When properly secured, bike transport covers are designed for highway travel. Always make sure all straps, buckles, and elastic hems are fully fastened before driving at speed.

Do bike rack covers protect from rain?

Yes. Water-resistant materials help protect bikes from rain and road spray during transport.

Do bike rack covers protect from sun damage?

Yes. UV-resistant fabrics help prevent fading and deterioration on your bicycles when transported in direct sunlight.

Will the cover fit electric bikes (e-bikes)?

Some covers fit e-bikes, but it is best to check the product dimensions carefully due to their larger frame sizes before ordering.

How do the covers stay secure while driving?

Most covers include straps, buckles, and elastic hems to keep the cover tightly secured during travel. Double-check all attachment points are properly fastened before hitting the road.

Can the cover be used for bike storage?

Yes. Bike covers can also be used to protect bikes when stored outdoors or in partially covered areas when not in use.

Will the cover fit all bike racks?

Our covers fit most hitch-mounted racks, but compatibility may vary depending on rack design and size. Check the product page or contact our team if you have a specific rack model you'd like confirmed.

Is there a how-to video for installation?

Yes — watch our step-by-step installation video here: Bike Cover Installation Guide →

Umbrella Canopies

Replacement Umbrella Canopies

Everything you need to know about finding, fitting, and installing a replacement canopy for your market or cantilever patio umbrella.

How do I measure my umbrella for a replacement canopy?

To find the right size, measure the length of one rib — from where it connects at the center hub to the tip. This rib length determines the canopy size. For example, a 9ft canopy has ribs measuring approximately 52"–54". You will also need to count the number of ribs (support arms), as canopy sizing depends on both rib length and rib count. Common counts are 6 ribs and 8 ribs.

What's the difference between 6 ribs and 8 ribs?

The ribs are the support arms that hold the canopy fabric open. A 6-rib canopy fits umbrellas with 6 support arms, and an 8-rib canopy fits frames with 8 arms. Using the correct rib count ensures a snug, proper fit — the wrong count will leave the canopy loose or unable to attach.

Will these canopies fit cantilever umbrellas?

We do carry cantilever-specific replacement canopies for both hanging and supported-bar styles in 10ft and 11ft 8-rib sizes — so yes, we have you covered. However, standard market patio canopies will not fit a cantilever frame at all. The designs are completely different and are not interchangeable. Make sure you select a canopy specifically listed for cantilever umbrellas, and confirm your rib count and diameter before ordering.

Are the replacement canopies waterproof?

Our canopies are water-resistant, treated with a water-repellent finish to handle light rain and drizzle. They are also UV-protected to help prevent fading and sun damage over time. They are not designed to withstand heavy, sustained downpours.

How do I install a replacement canopy?

Remove your old umbrella fabric, slip the new canopy over the top of the umbrella frame, and secure each rib into the canopy pockets. For cantilever umbrellas, unfasten or unzip the old fabric and replace it with the new canopy. Installation typically takes just a few minutes.

What colors are available?

We carry over 50 colors, ranging from neutral tones like beige, tan, and taupe to bold options like blue, yellow, red, and more. This lets you refresh your patio with a seasonal update or match your existing outdoor décor.

What if the umbrella pole diameter is bigger than the grommet hole?

Our grommet hole is 3/4" diameter, which is mainly cosmetic. You can cut around the grommet to enlarge the opening — once the finial is screwed back on, it functions fine. To prevent fraying, seal the cut edges with fabric glue, clear nail polish, or an anti-fray product like Fray Check or Fray Block (available at most craft stores). Please note: cutting or modifying the canopy will void the product warranty.

Do I need a new umbrella if the ribs are broken?

If your umbrella ribs or joints are damaged, purchasing a new umbrella frame is usually the best solution. However, if the frame is structurally sound, a replacement canopy is a cost-effective way to give it a fresh look without the cost of a full replacement.
