39THIRTY

The 39THIRTY is a style of baseball cap manufactured by New Era. It is characterized by its fitted, pre-curved brim and a stretch-fit back. Unlike a traditional snapback or strapback cap, the 39THIRTY does not have an adjustable closure. Instead, it is available in a range of sizes, similar to how fitted caps are offered, to ensure a snug and comfortable fit for the wearer.

The design of the 39THIRTY aims to provide the look and feel of a fitted cap with the added comfort of a stretchable material. The fabric used in its construction typically incorporates spandex, allowing the cap to conform to the wearer's head. This combination of a pre-curved brim and stretch fit makes it a popular choice for both casual wear and as fan apparel for sports teams. New Era offers the 39THIRTY in a wide variety of colors and with different team logos and designs. Its silhouette is generally considered to be a mid-profile cap.
