YKK is a pioneer in the development of lightweight buckles.
We are pleased to announce that we have released a next-generation buckle called the “Ultra-Lightweight Buckle.”
This new buckle features a well-balanced weight, strength and function.
YKK is constantly developing new technology for light weight products.

By cutting out the lower center part of the socket and shortening its length, YKK has made the LB-LW buckle ultra-lightweight and strong.

The socket’s flexible form makes it durable and resistant to breakage.
Its structure also makes it possible to remove the rib from the socket without impairing its smooth performance, since each leg is led directly into its track.
