Futon filled with technology and down

This duvet is made with a focus on quality, making use of our know-how in creating sleeping bags that keep you warm even in harsh outdoor environments. NANGA is a brand that specializes in down products such as sleeping bags and down jackets, and manufactures products by combining the skills of Japanese craftsmen. NANGA, which has developed a wide range of sleeping bags and other products designed to be used outdoors in the cold, has poured its long-cherished commitment to warmth into duvets for everyday use. Since this is a duvet that you will use every day during the cold winter months, we recommend choosing one that is reliable and of high quality.

Return to NANGA's origins

A down duvet single designed for lightness and comfort. In addition to using lightweight, high-quality down, NANGA, which specializes in down products, makes full use of its technology, including sewing, packing technology, and down distribution.

The main feature is the sewing of the quilt and each chamber (a small room separated by a quilt). In order to take advantage of the volume of the down, the height of the small room where the down is stored is set higher than usual. Furthermore, it has been designed to have a good balance between the amount of feathers and the weight when hung. In order to lower the center of gravity and reduce slippage, we use lightweight 80-cotton sateen for the upper fabric and 60-cotton satin for the lower fabric.Delicate and careful attention to detail that cannot be seen at first glance makes it comfortable. A duvet that supports a good night's sleep.

For the feathers, we use NANGA Select Premium Down x Kawada Feather White Duck Down from Spain in a ratio of 90% down and 10% feather. The quality of down varies greatly not only by the breed of waterfowl, but also by the environment in which they are kept and the length of time they were kept. The feathers selected for this duvet are from ducks raised in a carefree and hygienic manner on the vast land of Spain. Down is durable and has strong resilience, while feather is supple and soft. It has excellent heat retention, insulation, and elasticity, making it the perfect material for duvets that are worn on the body all night.

It can be called a return to NANGA's origins, as it is made with a combination of NANGA's technologies and a focus on comfort. A domestically produced down duvet single that improves the quality of your sleep and provides a healthy night's sleep.

Domestic production to maintain quality

While many manufacturing companies in our industry are shifting to overseas production, NANGA continues to produce domestically. The reason is to maintain quality. There are manufacturing backgrounds unique to down, such as the fact that there are many cases of falsification of the country of origin and country of manufacture of expensive down, making it difficult to verify the quality unless you are the producer. We carry out a series of tasks ourselves, from cleaning the down to sewing and inspecting it, and our strong desire to hand it over to users with confidence is why we manufacture it domestically.

Another thing that is essential when talking about NANGA down is the Japanese craftsmen. The sewing technology is unique, and we have gathered the know-how to meet a wide range of demands from mountaineers who are exposed to life-threatening conditions to weekend hikers. Japanese craftsmen are good at detailed work, and they strive for not only aesthetically pleasing finishes, but also high durability and comfort.

High peaks of the Himalayas continue to challenge to overcome difficulties

NANGA's predecessor was Yokota Seishi, which was founded in 1941 and manufactured kotatsu futons and mattresses. In the 1960s, the company changed its name to Nanga in order to continue manufacturing in Japan, and became known not only to Japan but also to mountaineers around the world as a manufacturer of sleeping bags and down using high-quality down. NANGA is the ninth highest mountain in the world, Nanga Palpat, located in the Himalayas and has an altitude of 8,125m. It is known that it is extremely difficult to climb and many people have lost their lives to the top, but the reason behind choosing the name of the mountain as a brand is the strong will to continue to take on challenges to overcome the most difficult conditions. there is.

The philosophy of manufacturing is honesty, simplicity and robustness. We are so particular about the safety and quality of our feathers that we even offer a lifetime warranty on our sleeping bags. We hope that the down jackets and sleeping bags we make will feel safe, secure, and comfortable for everyone who uses them.
