The quick answer

We recommend the Near Zero NZ 20 for backpackers and cold-weather campers who want serious warmth for very little weight. Price $299.50; $269.55 with code SEBASTIANBASSOL (10% off). Best for backpackers and cold-weather campers who want a light, packable 850+ down bag at a mid-range price.

Our verdict

An 850+ fill down mummy bag with an 18°F comfort limit at 1 lb 13 oz.

We recommend the Near Zero NZ 20 for backpackers and cold-weather campers who want serious warmth for very little weight. The Regular weighs 1 lb 13 oz and holds 470 g of 850+ fill power white duck down certified to the Responsible Down Standard, with a 28°F comfort rating and an 18°F comfort limit. A hood with an adjustable collar, shoulder and zipper baffles and an internal pocket keep heat in and gear close, and it compresses to roughly 12 by 6 inches, about the size of a 32-oz water bottle. At $299.50 it brings premium down performance to a much friendlier price.

Who should buy the NZ 20

The NZ 20 is a fit for backpackers, hunters and cold-weather campers who want a down bag that is light and packable without a boutique price tag. It suits fall and spring trips and winter car camping.

Warmth and weight

Near Zero fills the Regular with 470 g of 850+ fill power white duck down, certified to the Responsible Down Standard. It is rated 28°F for comfort, 18°F for the comfort limit and 12°F for extreme conditions, and the Regular weighs 1 lb 13 oz.

Heat-trapping details

The hooded design has an adjustable collar and pull strings, and shoulder and zipper baffles block drafts. An internal pocket keeps a phone or headlamp within reach.

Sizes and packing

Short (73 in), Regular (80 in) and Long (87 in) options fit users up to 5 ft 6 in, 6 ft and 6 ft 6 in. The included compression sack packs the Regular to roughly 12 x 6 in, and a mesh sack is included for long-term storage.

Why we like it.

Premium down at a fair price

850+ fill power white duck down, certified to the Responsible Down Standard, gives excellent warmth for the weight.

Light and packable

The Regular weighs 1 lb 13 oz and compresses to roughly 12 x 6 in, about a 32-oz bottle.

Draft-blocking design

A hood with an adjustable collar, plus shoulder and zipper baffles, keeps warm air in.

Three sizes

Short, Regular and Long fit users up to 5 ft 6 in, 6 ft and 6 ft 6 in.

Handy details

An internal pocket holds a phone or headlamp, and a mesh sack is included for storage.

A few things to consider.

Mummy cut is snug

The mummy shape is warm and light, but it gives less room to move than a rectangular bag.

Down needs care when wet

The 10D shell is water resistant, but keep the bag dry and store it uncompressed in the mesh sack.

Rated for cold, not extreme cold

An 18°F comfort limit suits three-season and shoulder-season trips; pick a warmer bag for deep winter.
