Hat Terminology


This refers to the top of the cap.  The crown of the cap is made up of panels. Typically there are 6, but you can have 4 or 5 as well.  There are a few jewels in this crown that make it all come together – things such as buckram, buttons, sweatbands and eyelets.



I mentioned buckram above, but what on earth is buckram? It is the stiff woven fabric that is put into the front two panels of the crown to make a structured cap. This buckram gives you just the right height you want to stand out in a crowd. But if you don’t like structure and are more of a relaxed, easy-going person, the unstructured crown is the way to go. No buckram and a heavy wash make for a soft, comfortable fit. According to multiple headwear companies, the unstructured, low profile cap is the best selling cap in their product lines.



This is the band of fabric lining the inside bottom of the crown that touches the head. The sweatband serves multiple purposes. Depending on the fabric, the sweatband can make a cap very comfortable and can also help wick moisture away. There are even cooling sweatbands that actually reduce the temperature of the fabric by 5 degrees or more.



The button is the jewel on top of the crown and helps hold all the panels together. It is either metal or plastic and is covered with the fabric used on the cap.



Most caps have 6 embroidered holes, one in each panel to allow for ventilation. But if the cap has mesh back panels, the eyelets are typically left off since the mesh takes on the ventilation role. The eyelets can be sewn or metal.



A lot of people call this the bill or brim, but visor is the technical term. The visor can be flat, pre-curved or even slightly pre-curved. It is a piece of plastic attached to the front of the crown and is covered with the fabric of choice. This is where the sandwich comes in. The sandwich is an extra layer between the top and bottom of the visor that is a different color or can have a woven label with a logo on it. The sandwich adds a little flavor to the cap and is another spot where you can personalize the cap.



This is one of the features that will help sell the cap. There are fitted, stretch fit and adjustable closures. Fitted caps have a closed back and are sized by inches. You have to know the size of your head to know which cap would fit you the best. The stretch fit has a closed back as well, but the magical term is stretch – the fabric and sweatband have stretch in them so that these caps can fit a range of sizes. They typically come as S/M, M/L or L/XL.
