NANGA's technology and philosophy
NANGA specializes in using high-quality down and manufacturing our products in Japan. We rigorously select only down that is imported from Europe and washed in Japan. Naturally it is free of any impurities, and there is almost no trace of that distinctive down smell. A sophisticated refining process is necessary to maximize the potential of the characteristics of down. The quality of Japan's purification process is second to none when compared to other countries. Our products are sewn in Japan by only the most skilled artisans.

01. Drawstrings
The drawstrings feature cord locks to help adjust the temperature and fit of the sleeping bag.
02. Shoulder warmer
A tube filled with insulating material in the shoulder area prevents warm air from escaping. The shoulder warmer is equipped primarily on sleeping bags rated for three seasons or more.
03. Draft tube
The internal tube blocks cold air from coming in through the gaps in the zipper and improves thermal insulation. As with the shoulder warmer, the draft tube is featured primarily on sleeping bags rated for three seasons or more.
04. Zipper
Equipped with YKK 5C, which is considered to be the optimal zipper for sleeping bags based on strength testing by YKK.
05. Sizing
The regular size has a maximum length of 210 cm and a maximum width of 80 cm, making for a comfortable and roomy bag. Long and short versions are also available.
