The one-size-fits-all Blank Flexfit Hat Cotton Twill Cap is constructed with Yupoong's patented technology. A specialized spandex material is weaved throughout the sweatband and crown of the hat for genuine Flexfit comfort. 6-panel, mid profile cap is made with six pieces of fabric bringing back the look of the 1950s pro-ball caps. Our Blank Flexfit Hat Cotton Twill Cap features solid buckram lining in the crown, common to most structured caps. This hat is also manufactured with eight rows of stitching for more sturdy and well-performing headgear. Strong, soil-resistant fabric keeps your Flexfit twill cap looking new, while the patented Permacurv PE Visor preserves the natural arch of the hat.
