Guide to Convertible Tops (2024)

Almost all manufacturers use Haartz fabrics. They may specify "heaviest weight" or "original replacement" in ways that seem reassuring. But they do not really tell the whole story. Please bear in mind that two things dominate, by far, the quality issue: (a) the manufacturing quality control in the factory that makes the top and (b) the care and thoroughness of the installation. There is a trade-off in weight: heavier is better for resisting tear through, but lighter is better for flexibility and abrasion from within that may arise from movement. Almost all our tops are a flexible medium density (36 oz.) fabric.Heavier is not better in most cases. Where it is, because of the top design, we will say so and the top will be made of the heavier vinyl.
We will be happy to quote you on a "true double texture vinyl" top. This is a pinpoint with a butyl rubber core, like our stayfast. Generally these tops are about 30 percent higher in price than the regular pinpoint version.Sonnenland®(View)is a German-made 3-ply topping made up of an acrylic twill-weave facing, a rubber inner-layer, and a polyester "dobby backing." The dobby backing is a knit-like weave original to many high-end foreign cars. Customers who value originality over cost often pay top dollar for Sonnenland, just to have that authentic "dobby backing," seen only when you look up at the roof of your convertible top from inside your car. Sonnenland canvas is a top-of-the-line material original to various Audi, BMW, and Jaguar convertibles, among others. Sonnenland Canvas can vary in terms of surface weave and/or weight for acoustic performance, but all Sonnenland Canvas promises elegance and long-lasting durability.

Twillfast®(View), also called Sonnendeck Canvas, is an American-made canvas - a cost-effective substitute for Sonnenland. Twillfast is usually a 3-ply topping (though some versions are 5-ply) with Polyester and/or Polyester/cotton backings. This material, original to certain Camaro, BMW, Mustang, and VW Beetle convertibles, among others, varies in terms of surface weave and/or weight for acoustic performance. Twillfast Canvas is identical to Sonnenland Canvas - elegant and durable - only it's less expensive. This is a top-notch convertible top material, one we often recommend to savvy customers who like a good buy and a quality product.

StayfastCanvas(View)is an elegant, durable canvas original to cars like the Mazda Miata and the Nissan 370Z. Stayfast is commonly used in replacement convertible tops. Stayfast canvas has an acrylic square weave facing, a rubber inner-layer, and a cotton backing. As with other canvases, the rubber core gives the fabric long-lasting durability. Stayfast canvas is a sleek, beautiful canvas, usually less expensive than Twillfast, but it does not have the dobby backing offered in Sonnenland and Twillfast (Sonnendeck). Stayfast is a popular upgrade to vinyl convertible tops, and as with any canvas, is richer looking and has a higher wear rating than convertible tops made of vinyl.

HaartzPinpoint Vinyl(View)is the most popular fabric. This vinyl design is original to most American cars from the fifties to the nineties. Pinpoint refers to the little dots or pips that you see if you look closely at the vinyl surface. European cars, such as the old Beetles and others also used pinpoint vinyl as the topping fabric.

Chrysler Sailcloth(View)is featured on many late LeBarons, Sebrings, certain Mustangs and other cars. It is structurally (wear quality) equivalent to the Haartz Pinpoint but has a different surface grain. The grain was designed to imitate the look of canvas. As you can see from the scan of this fabric, it is an exceptionally rich looking material. It is sometimes chosen for replacing convertible tops that originally featured pinpoint vinyl.

CabrioGrain(View)is also structurally equivalent to the pinpoint. It has a pigskin outer grain vinyl as original to Volkswagen Cabriolets from 1984 onward and to Mazda Miatas and Mercury Capris.

A5S German Canvas (Robbins)The 100% Acrylic Twill Weave Surface Cloth receives a special flame singing treatment to remove the fabric knap; and is laminated to Black 100% Polyester Dobby backing.

This is the original topping for Porsche Boxster and Cabrio convertible tops. 59 inches (150 cm) wide, made in Germany.

British Bison (also called Colonial Grain)(View)is the American made crush grain vinyl that imitates the much more expensive British Everflex vinyl original to many British convertibles. Color selection is limited. These are often referred to as 'crush grain' or 'leather grain' vinyls. They are structurally equivalent (wear rating) to the pinpoint, cabrio, and sailcloth vinyls.

BritishEverflexVinyl(View)We are now pleased to offer British Everflex Vinyl for classic English tops. This is the original material used on British convertibles including Jaguar, Rolls Royce and many others. Imported from England, British Everflex vinyl is a supple vinyl with a rich appearance and is more durable than other vinyls. A good, less expensive alternative is Colonial grain vinyl. Colonial has the same texture but is less durable.

HV Denim (also called Twill Weave Vinyl)(View)is heavy duty sport material composed of a distinctive twill grain PVC outer layer and a polyester/cotton blend inside lining fabric.
