Antique Triangle Backpack – Large
Featuring leather with rich tonal variations as the centerpiece, this backpack is shaped with a triangular base and top tucks to create an organic silhouette. The design tapers toward the top, keeping the lines sleek even when fully loaded, while maintaining an elegant profile from behind. Inside, a foldable bottle holder adds practical convenience. The large size includes a dedicated pocket that fits a 15-inch laptop, making it an ideal choice for those seeking both style and functionality in business settings.
Bring a touch of individuality to your everyday style with the organic triangular silhouette created by the tucks.

Delicately folded tucks at the top create a distinctive triangular profile. This striking silhouette is crafted from a single piece of leather extending seamlessly from the front to the base, showcasing the leather’s naturally soft fullness alongside the clean, straight lines of the back. Accented by a front pocket, the rich tones of the antique leather add playful depth, creating a sophisticated yet relaxed adult casual style.

Attention & Care
This product is finished with a high-transparency coating (aniline finish) to highlight the natural texture of the leather.
Due to this finishing method, contact with water or sweat may cause stains, watermarks, or color transfer. We recommend applying a waterproof spray periodically.
If the bag gets wet, gently wipe it immediately with a dry cloth.
Made in: Matrigul Factory, Bangladesh
