If an advertisement stated, "Our wine is made with French grapes", as a knowledgeable chef  you would not be impressed since you know that there are many varieties of grapes grown in France.

When a chef's jacket (chef's coat) is described as being made of "Egyptian cotton"...

There are many varieties of cotton.  All cotton grown in Egypt is "Egyptian" cotton, but it is not all Extra-Long Staple (ELS) cotton.  Egypt is one of the largest producers of ELS cotton in the world, but it consumes much of what it produces.  The majority of what it exports is long staple cotton, not ELS cotton.  However, the description "Egyptian cotton" conjures in the mind of many consumers the image of the very finest.

Bragard® (known for Egyptian cotton chef jackets), has this to say regarding our position on this subject.

The finest, most sophisticated cotton in the world is American Pima cotton, grown exclusively in the American West and Southwest.  This special fiber is up to 50% stronger than other cotton varieties, and is so rare that it represents just 3% of all the cotton grown in the United States.

The name Supima® is a licensed trademark owned by the Supima® Association of America, and is the consumer’s only guarantee that a product is made of 100% Extra-Long Staple American Pima cotton.

Because of our unparalleled attention to detail in tailoring, we were awarded a Supima® licensing agreement.  These contracts are not awarded lightly.  The applicants must meet requirements insuring the highest level of quality and integrity for any products bearing the Supima® brand. 

Supima®  is the only cotton used in chef coats bearing the Crooked Brook® label.
