What role do the eyelets and rivets attached to the hoodie zip-up pocket play during actual wear?

An eyelet is a subsidiary material wrapping a metal rim around a small hole pierced in the fabric, and a rivet refers to an accessory that compresses and fixes overlapping parts of cloth with a metal stud. In clothing, rivets serve to hold pocket corners firmly so they do not tear, as they endure the most pulling force when putting hands in and out. The eyelets used alongside also protect fabric holes from fraying while aiding ventilation and adding a visual impression.

THREE TO EIGHTY's EYELET POCKET HOODIE ZIP-UP CHARCOAL places irregular metal eyelets along with graphic points on the front kangaroo pocket^[2]. In particular, all eyelet and rivet subsidiary materials incorporated into the pocket front utilize non-toxic subsidiary materials from the global manufacturer YKK^[3].

Components such as nickel included in general metal accessories easily react with sweat or friction, causing skin itchiness or allergies. A hoodie zip-up's pocket is an area where bare skin easily comes into direct contact with metal as hands are repeatedly pushed in and items are pulled out. Applying non-toxic subsidiary materials means that even if metal parts brush against the skin when inserting hands, it can be worn comfortably with less concern about irritation. The brand explains that by using YKK non-toxic subsidiary materials harmless to the human body, it features high quality and safety^[4].
