Fitted flat billed caps are very popular right now, but what makes this one stand out above the others is its unique blend of fibers. The acrylic/wool/spandex blend allows flexibility which helps the cap retain its shape over time. It's also very easy to clean, and keeps the color vivid. You get all of this plus the great added features of sewn eyelets and a high profile, 6-panel design you expect in a good hat.
