The Ultimate Custom Flexfit Hat Guide

What is Flexfit Technology?

Flexfit technology is what makes fitted Flexfit hats so unique. These hats are made by weaving polyurethane spandex into their sweatband for a comfortable stretch and fit. This technology is incorporated throughout the crown of the cap, providing elasticity and a perfect blend of comfort and style. Flexfit hats are known for their comfort and versatility, making them one of the best blank hat brands.

Flexfit continues to come up with inventive technologies to make their hats stand out from the competition. These include flexible visors, Permcurv for maintaining shape, Ultrafibre for strength, Ecodry for environmentally friendly water repellency, Cool & Dry for wicking perspiration, Pro-formance for a premium look and feel, Hyper Tech for conquering all elements, and Hybrid Tech for ultimate comfort.
