  • Adjustable cap
    Patent number: 4651352
    Abstract: An adjustable cap includes a pleated crown whose central pleats have less transverse dimension than the lateral pleats to better maintain the contour of the crown for front and rear head room for relatively small cap sizes. The pleats are secured to each other at the rear of the cap to prevent exposure of the head between the crown and headband.
