Our Materials

Quality Materials and Craftmanship

At GBY, we prioritize quality and durability in every product we create. Our commitment to using the finest materials ensures that our ultralight backpacks are not only lightweight but also robust and reliable for daily use. We combine minimalist design, quality materials and high-end craftsmanship to deliver superior products.

YKK Zippers

We use only custom Japanese YKK water-resistant zippers and sliders on all our bags. YKK zippers are renowned for their durability and smooth operation. While some manufacturers may claim their zippers are "waterproof," we prefer to provide an accurate description: our YKK zippers are highly water-resistant, offering excellent protection against the elements. The superior quality of YKK ensures that our bags stand up to daily wear and tear without compromising on performance.
