The NZ 20 mummy sleeping bag meets the needs of high-altitude mountaineering expeditions, as well as for camping & hiking. Our mummy sleeping bag has a hood that minimizes heat loss & keeps your head comfortable, while the shoulder and zipper baffles keep your core warm by preventing the cold air from coming into the bag. The shoulder collar pull string and the hood pull string add to its effective design that traps body heat & keeps you toasty when it gets below 0ºC. Along the shoulder collar, we’ve added a pocket to store items such as a cell phone, flashlight, or heat warmers. The entire bag packs down to nearly the size of a 32-ounce water bottle.

With 850+ fill power white duck down insulation, premium 10D taffeta lining, and high-quality shell fabric construction that is durable enough to sustain intense use over a long period.

The NZ 20 sleeping bag has a comfort limit temperature rating of 18°F or -8°C and a comfort temperature rating of 28°F or -2°C. This sleeping bag is ideal for most mild to cold weather camping trips. Higher fill power means a warmer bag for its weight. Our outdoor camping sleeping bag has 850+ 95% white duck down insulation, the highest in the market, more than any other sleeping bag at this price range. All sleeping bags include materials that are RDS (Responsibly Down Standard) certified.

All sizes are right-side zippers.

Warm, compact and Ultralight!

I paired this bag with a sea-to-summit silk mummy liner and two sleeping pads and was plenty warm with low temp of 27 on first night and 25 the second night! Definitely recommended!!


This bag is nice and light, packs down to a small footprint and kept me toasty warm in sub 40-degree temps. This is a great bag, well designed, great quality. Love the bag. My feet are generally cold and I had zero problems. This is the best sleeping bag I have owned. Sorry, I forgot to take pics of the bag on our backpacking trips.

Best bag!

This is by far the most comfortable bag I have ever used. I slept in it again last weekend at 11,000 ft and loved it. The hood is fantastic and fits easily over my head and eyes. I am 6'2 and have the long version. Definitely worth purchasing!

I love this bag!

Got it for month-long backpacking trip on the PCT and found it to be perfect. It was soft and warm on the cold nights, and comfy to sleep on top of for the warmer nights. Compresses easily and very light-weight to carry in my pack. Zipper is great, no catching or snagging. Great bag all around.
