What kind of closure is the 'metal fireman hook' mentioned in the description?
While reading the flight jacket's description, the closure method referred to as a fireman hook instead of typical buttons or zippers may be unfamiliar.
It is a clasp device derived from firefighters' protective turnout gear that firmly interlocks and fastens the garment placket by hooking and snapping the latch into place.
A fireman hook refers to a specialized clasp designed to quickly and reliably open and close garments even while wearing thick gloves. Because it works by catching a hook into an opposing ring and flipping a lever to lock it, it provides stronger fastening power than standard buttons or zippers, and the hardware grasped by hand is larger in size.
INSILENCE applied this metal fireman hook to the front placket closure of the 백사틴 MK3 플라이트 자켓 BLACK[1]. While showing off the functional mood of a military flight jacket, it serves to tightly fasten the front and maintain its shape.
hmmm, along with the tactile sensation of directly flipping the latch to lock it, the exposed metal texture itself completes the garment's sturdy impression.

The specific type of metal material or plating specifications for the fireman hook hardware have not yet been confirmed.
