【Winter Down】A collaboration limited down jacket using sulfur-dyed black denim that you can love beyond time
The project by Yohji Yamamoto, WILDSIDE YOHJI YAMAMOTO, announces its second collaboration with Rocky Mountain Featherbed. The "Down Jacket Denim," made with sulfur-dyed black denim fabric, is a denim jacket that develops its own deep texture as you wear it.
The collaboration item released on November 5th
"Down Jacket Denim" born from the collaboration between WILDSIDE YOHJI YAMAMOTO and Rocky Mountain Featherbed. This denim jacket is made from Japanese sulfur-dyed black denim fabric, with a natural fade treatment that enhances its character the more you wear it.
The design features a yoke made from washable cow leather. This design combines the unique texture and ease of maintenance of leather, which is also a key point.
The lining uses durable ripstop fabric. The calm burgundy color adds an accent, creating an elegant and easy-to-style impression. It also has an inner pocket with a zipper to safely store valuables.
The down, which is a symbol of Rocky Mountain Featherbed, achieves both high insulation and practicality. The high-quality European down (90% down, 10% feather, 700 fill power) is treated with a water-repellent finish, making it resistant to rain and snow, and it keeps excellent warmth even in harsh environments.
With a wide range of sizes from 40 to 46, you can select according to your body type and preferred style. This is a piece you want to incorporate into your wardrobe as the main outerwear this winter.
