Crafted with "Eco Yarn"

Two collaborative items, designed by Y’s based on Cote&Ciel's iconic "Moselle" and "Isar" bags and backpacks, are re-released.

Cote&Ciel is known for its practical, ergonomic designs that fit the human body, allowing for easy access to office essentials, particularly laptops.

This collaboration enhances Cote&Ciel's appeal with meticulously detailed designs that lean into a fashion-forward aesthetic.


The "Small Isar Echo" is based on the "Small Isar," a model for those seeking a futuristic, compact bag. Its size is easily manageable for women, and it's a unisex item suitable for men looking for a small, functional backpack. The water-repellent tape on the zipper is made of black leather.

The zipper pulls and black leather tape are original designs exclusive to this collaboration. The leather features an embossed "côte & ciel+Y's" logo, adding a touch of exclusivity.

Meanwhile, the "Moselle Echo" is based on the "Moselle" model, characterized by its raindrop-shaped silhouette. It also features subtle black leather detailing, covering the nylon tape of the zipper.


While typically featuring an inner pocket, the collaboration model has an external one. This allows for easy access to small items and adds a visual accent to the bag's appearance.

Both models utilize "Eco Yarn" as the main material, a durable fabric developed through environmentally friendly processes. Despite its functional properties, the matte texture lends a chic finish to the items.

The padded laptop compartment inside has been simplified, retaining its functionality while softening the ruggedness of the ergonomic design, creating a look that blends human-centered functionality with nuanced aesthetics.

The shoulder straps of the "Moselle Echo" feature inserted padding instead of standard webbing, making them comfortable to wear. The stainless steel adjuster on the shoulder strap is also adorned with the "côte & ciel+Y's" logo.
