The traditional 6 panel ballcap has a fused buckram skeleton that forms the rounded athletic 3 1/2" crown. Spandex has been woven into the cotton twill cap to allow for maximum stretch and comfort. Each panel has a tonal thread sewn eyelet for ventilation. The inner elasticized sweatband stretches for fit, just like the cap.
