JP-Original Down Parkar

The original down jacket created for the Japanese Antarctic Research Expedition

With the arrival of winter, the problem of creating truly practical outerwear becomes more and more important. We wanted to create something authentic and historically significant, while also focusing on core functionality and weather resistance. We also wanted to make a truly “Made in Japan” product that would honor the legacy of the original design.

Nowadays, down outerwear is not just a winter garment to protect you from the cold, but a crucial element of winter styling. Today a wide variety of options are available, but most cannot come close in terms of balancing both style and functionality.

We would like to introduce Japan's first down jacket designed for extremely cold climates. This jacket was instrumental in aiding the progress of the 1957 Antarctic Research Expedition.


Zanter was founded in 1951 and became the primary down producer for Japan’s arctic explorers. Our JP-Original Down Park is the successor to the original down-insulated gear that was supplied to the Antarctic research team of the past. Since its first release, the JP-Original Down Park has been tweaked and modified over the years to produce one of the most weather-resistant garments on the market today.

A high-spec down garment of supreme quality that is favored by explorers

The natural duck down is aged for 90 days and washed in its country of origin, then it is further refined in Japan in a process that takes as many as 10 steps to remove dirt and impurities. This specific down is designed to withstand temperatures as low as -60°C. Much of the appeal of this product comes from its authentic design, historical significance, and extreme performance in frigid temperatures. Generally, 600-700 fill power is considered to be good quality down, and 700 fill power or higher is considered to be high quality down, but this product boasts 800 fill power domestically refined down.

The outer material is made of BREATHATEC, a three-layered breathable and waterproof material. We have also blended in DELFY, a water-repellent fabric developed from Toray Industries’ cutting-edge textile technology to provide high water repellency and wind resistance. The fabric is designed to repel heavy rain, as well as prevent the inside of the garment from becoming stuffy due to perspiration.

Additionally, the deodorant fiber MOFF affixed to the back of the garment has an anti-odor and antibacterial effect. It works to curb excess perspiration, preventing any odors after long periods of wear.


Functionality and comfort in the coldest climates

Naturally, the heat-retaining properties of the garment are the most critical element of its design. The jacket effectively wraps around the body to keep it warm and to keep body heat locked in. However, we have included some supplemental detailing to add even more functionality to the garment.

The jacket is double-fronted to prevent wind, rain, and snow from entering the jacket, and the deep hood can be worn while wearing a helmet without exposing the ears and neck to the cold air. These are exactly the kind of specifications that are needed to stay comfortable in record-cold weather conditions.


Despite its obvious toughness, the inner lining is as soft as a high-quality down quilt. The JP-Original Down Park is nothing short of a reliable masterpiece that protects from the harsh winter cold. With its groundbreaking high-spec design, it is sure to be a down jacket that will stand the test of time.
