When it comes to NANGA down products, jackets are not the only thing worth checking out. For outdoor use, the brand’s highly functional sleeping bags deserve just as much attention. Here are three models with official purchase pages confirmed as of September 2026, compared by their strengths: all-around performance, extra room, and ultralight design.
AURORA TEX light 380DX
A classic choice with waterproof-breathable protection
Priced from ¥49,500 including tax, this model uses NANGA’s proprietary waterproof-breathable material, AURORA TEX LIGHT. It helps protect the down from condensation and moisture inside a tent. Versatile enough for both camping and hiking, it is also a great choice for anyone buying a serious down sleeping bag for the first time.

AURORA TEX SQUARE FOOT 400
More room around your feet for extra comfort
Priced at ¥45,100 including tax, this model features a square-shaped foot area that allows more freedom of movement than a traditional mummy-style sleeping bag. The L-shaped zipper opens wide, so it can also be used more like a blanket. It is ideal for car camping, spring-to-autumn camping, or anyone who finds tight sleeping bags uncomfortable.

MINIMARHYTHM ZERO
An ultralight sleeping bag at around 325g
Priced at ¥49,500 including tax, this model uses 180g of down and weighs approximately 325g in total. Its packed size is about φ13 × 20cm. It uses 770FP highly water-repellent down, and NANGA lists a lower-use temperature of 0°C. It is a great match for hiking, UL trips, and summer mountain camping where keeping your pack light matters.

Choose the 380DX for waterproof-breathable performance and versatility, the SQUARE FOOT 400 for extra room around your feet, or the MINIMARHYTHM ZERO for portability. Think about the season, how you travel, and how much gear you want to carry to find the model that best fits your style.
