A backpack that lets you enjoy sculptural beauty, luxuriously crafted from a single piece of leather, and expressing individuality through a new expression of antique leather.
Antique Triangle Backpack
Featuring leather with beautiful tonal depth, this backpack combines a triangular gusset and top tucks to form an organic silhouette.
Its tapered upper design keeps the profile sleek even when packed, while a foldable bottle holder and space for a 14-inch laptop make it ideal for both work and everyday use.
Make your everyday look uniquely yours with the tucks’ triangular, organic form.
Delicately folded tucks at the top create a distinctive triangular side profile. Supporting this unique form is a single, seamless piece of leather used generously from the front panel to the base.
The natural softness and fullness of the leather coexist harmoniously with the clean, straight lines of the back panel, resulting in a composed and elegant expression.
An accent front pocket adds character, while the antique leather’s rich tonal variations bring a playful yet effortlessly refined touch—perfect for an adult casual style.

By adding folded tucks on both sides, we created an organic silhouette that forms a triangular shape when viewed from the side. Even when worn on the back, it maintains a balanced volume, sitting neatly against the body for a clean and streamlined look.
