The original factory top, referred to as the Factory Style Top, is a 2 piece design with the window section zippered into the top deck section and fits model years from 1989-1997. This 1 piece top design is an economical alternative for model years through 1990-2005 that retains the same quality as the original.

The window is an exceptionally clear, heavy 40 gauge press polish plastic for superior visibility. The top deck is made with a deck seam down both sides. All seams are heat sealed. To add to the strength, the seams are reinforced with a double stitch for extra support.

Manufactured using premium 38 oz. Cabrio Vinyl manufactured for that original look and feel. This is the same weight and grain found on the original Miata convertible tops. It is a two-ply composite made of PVC cabrio grain and a 100% polyester lining fabric, which is superior in strength, durability and flexibility to standard cotton backing convertible tops.
