• Fit Technology: This is a Flexfit brand cap, which features a patented "one-size-fits-all" technology. It uses a polyurethane spandex sweatband and stretchable fabric throughout the crown to provide an adaptive, snug fit for various head sizes without needing an adjustable strap.
• Patent Information: The tag specifically references U.S. Patent No. 5862522, which relates to the specific construction of the stretchable "free-size" cap design.
• Brim: Features Permacurv® visor technology, designed to maintain its proper shape and curve over time.

This style of band merchandise, particularly featuring the cannabis leaf, was highly popular during the late 90s and early 2000s nu-metal era (associated with albums like Life is Peachy and Follow the Leader). 

• Vintage Appeal: Authentic tour merchandise or items from the late 90s and early 2000s are often more sought after by collectors than modern reproductions.
• Design Rarity: While various Korn logo hats are common, this specific combination of the band logo over a green leaf is a distinct design that appeals to niche collectors.
