Grades are a way of classifying the quality of Panama hats, which is done with reference to the quality and fineness of the straw used and the weaving of the hat. The finer the straw and the weaving, the lighter and more comfortable the hat will be; however, one common aspect is that they all share an indicator for the quality of the weave.

The word system describes the grading in words such as Fino and Super Fino (Fine and Super Fine). This system is a grading for top quality weaved hats and used in reference to Montecristi hats where superior Panama hats are made.

In meeting the weavers, some say “10 hebrons” or 10 threads.

With so many grading systems, it as an American expert who invented the number system referring to the WPI, Weaves Per Inch. Counting the weaves vertically and horizontally, i.e. 12 horizontally, 14 vertically.

At Little Havana Shop, we have chosen to use the number system of 3/4 for the lowest grade up to as high as grade 16 for a tighter weave for its simplicity. For a trained and expert weaver, however, just looking at the weave and the finish, one can discern its fine quality.
