A winter that doesn't make you bulky, but warm. That's what Descente Ortelaine and Côte-et-Ciel think of winter.

Winter is a time when the volume of a person's body increases by a factor of 1.2. The city is denser than usual with people wearing thicker clothes. These days, more and more people are wearing down jackets, filling the space even more.

. It's fun to see them squirming around, but it's the days when they are puffy and hard to move around that are the most annoying. I especially experience this when I commute to work, where my bag tends to get fuzzy and uncomfortable, whether I carry it on my shoulder or on my back.

The collaboration between "Descente Ortelaine" and "Côtes et Ciel" has created an item that solves this problem. The new backpack can be docked to the "Mizusawa Down," a staple of the Descente Ortelaine line.

This is the result of a search for a way to maximize each other's items , and the result is one of a kind. Only 155 pieces will be available worldwide.

The bag is an adaptation of one of the classic "SORMONNE" bags from "Côte-et-Ciel" and has a 3-way design. Incidentally, it can hold a 13-inch device. A notebook PC will suffice.

The jacket is based on the new 2022 "CHRONICLE" model , with an oversized silhouette with a reduced amount of down. It is also lightweight and comfortable to wear , and is designed to be easy to carry with a backpack.

By inserting the backpack straps through the zipper opening in the back shoulder area, the silhouette is not compromised. Of course, it also looks sharp on its own.

The front zipper features dual-zip ventilation: two rows of zippers and a mesh fabric in between let in outside air and release uncomfortable heat and humidity that can easily build up inside.

The lining is lined with Descente's proprietary heat-retaining material "HEAT NAVI" for a comfortable temperature. The quality of the down is assured through the use of traceable down, which is used in the procurement process of the down.

Sold at select DESCENTE stores, select Côte-Écielle stores, and online at each store. How about one of these smart down and backpacks filled with technology and ingenuity this winter?
