A goose-down mummy bag in four fill weights, 400 to 1,300 g, with a 400T 20D nylon shell, drawcord hood and shaped footbox. It's 210 × 80 cm, and the whole bag weighs 850 g to 1.75 kg.

The maker states 90% down at 800 fill power. We haven't lab-tested it, so our temperature guide is more cautious than the maker's.

Four warmths of the same honest bag.

Best for
Three-season hiking, high-country car camping and cold huts.
Think twice if
At 210 cm it suits people up to about 180 cm. Taller? Choose the Black Snow Long 225 cm.

  • Light 20D shell

    Lighter and more packable than heavier 400T bags of the same fill.

  • Up to 1,300 g

    Enough down for frosty high-country nights, on a proper winter mat.

  • Weights on every size

    850 g to 1.75 kg, so you know what you're carrying before you buy.

Warm enough for your trip?

Plan on the “warm to” figure: our own cautious guide, or the maker's comfort rating where that's what we quote. If you sleep cold, or you're not sure, add 5°C. And if you're torn between two bags, take the warmer one: a bag that's too warm, you unzip; one that's too cold, you can't fix at 2 am.

Compare it with every bag we sell
  • Black Snow 400 g Comfortable to about 8°C If you sleep cold, about 13°C
  • Black Snow 700 g Comfortable to about 2°C If you sleep cold, about 7°C
  • Black Snow 1000 g Comfortable to about −5°C If you sleep cold, about 0°C
  • Black Snow 1300 g Comfortable to about −9°C If you sleep cold, about −4°C

Read the full guide: trips, safety and what else to pack

  • Plan for the coldest night

    Hills, valleys and inland camps get much colder than the forecast for the nearest town. Check the overnight low for where you'll actually sleep.

  • If in doubt, go warmer

    Being too cold at night isn't just a bad night's sleep. A long, cold night in a bag that's too thin can tip into hypothermia, and there's no fixing it at 2 am.

  • The mat matters as much as the bag

    Down underneath you is crushed flat, so the ground steals your heat. Below freezing, use an insulated mat with an R-value of 4 or more.

  • Help the bag help you

    Change into dry clothes, eat something before bed, and wear a beanie. A bag holds warmth in, but it can't make it.

“Warm to” is the figure we'd plan on: our own cautious guide, or the maker's comfort rating where that's what the table quotes. About the temperatures: Our guide, not a lab rating. It is set on the cautious side because nobody has lab-tested this down. Brands like Sea to Summit pay for an independent EN/ISO 23537 test; nobody has done that for this bag, and we won't pretend otherwise. So compare on grams of down and bag weight first: they're physical quantities. How to read them

Complete your sleep system

A bag is half of a warm night. Here's what else makes it work, and what people usually add.

  • Ultralight Sleeping Bag Liner — Keeps Your Bag Clean, Adds a Little Warmth, Packs to a Fist
    Ultralight Sleeping Bag Liner

    The cheapest way to make a down bag last longer: sleep in this, wash this.

  • Egg-Crate Foam Sleeping Mat — R 2.5 With Reflective Foil, 330 g, Folds to 56 × 14 cm
    Egg-Crate Foam Mat

    The mat that can't go flat: closed-cell foam, R 2.5, and light enough to strap on anywhere.

  • Sleeping Bag Compression Sack — 210T Nylon, Four Straps, S to XL
    Compression Stuff Sack

    Squash your sleeping bag to half its size with four straps.

  • Down Sleeping Beanie — Duck Down Hat for Cold Nights in Your Bag, 100 g
    Down Sleeping Beanie

    A light down hat for the coldest part of the night, when your head is the only thing outside the bag.

A mat rated for the season

The ground takes more heat than the air, and down underneath you is crushed flat. As a rough guide: an R-value of about 2 for summer, 3 to 4 for three seasons, and 5 or more on snow.

A way to keep it dry

Wet down stops insulating. Pack the bag in its compression sack inside a dry bag or pack liner, and air it out when you reach camp.

Questions

Which fill weight should I pick?
Pick for the coldest night you expect: roughly 400 g for about +8°C, 700 g for +2°C, 1,000 g for −5°C and 1,300 g for about −9°C. Go one step warmer if you sleep cold.
Can two bags zip together?
Usually, when one bag zips on the left and the other on the right. Message us before you order two and we'll ask the maker for a matching pair.
How do I store it?
Travel in the compression sack, but store it loose at home (a big cotton bag, or hanging) so the down keeps its loft.
Which size should I buy?
As a rule, pick a bag at least 15 cm longer than you are, so your feet don't press into the down and make a cold spot. The spec table above gives the length, or the height the maker says it fits. If you're between sizes, or like to sleep with a water bottle or clothes inside, go up.
Are the temperature ratings lab-tested?
No. Each temperature on this site is either the maker's own figure, labelled maker, or our own cautious guide, labelled our guide. None of these bags has an independent EN/ISO 23537 lab report, so we lead with fill weight and bag weight: physical quantities you can compare. Treat any temperature as a starting point and allow a margin, especially if you sleep cold.
Comfort, limit, extreme: which one do I use?
Comfort is the temperature a cold sleeper stays comfortable at; limit is where a warm sleeper, curled up, still sleeps. Extreme is survival only: never plan on it. Most people should plan on the comfort figure, and on a warmer mat than they think they need.
How do I store and wash a down bag?
Store it loose in its storage sack, not squashed in the compression sack. Wash it rarely, with a down-specific wash on a gentle cycle in a front loader, then tumble dry on low with two clean tennis balls until no clumps are left. It can take a few hours. A liner means you'll wash the bag far less often.
When will it arrive?
We dispatch in 1–3 business days, then it's 10–20 business days on the way to Australia. There's no warehouse or shopfront in between, which is why it takes longer and costs less. If you have a trip booked, order at least four weeks before you leave. You'll get a tracking number by email when the parcel is scanned. Full details on the Shipping page.
Will my order arrive in one parcel?
Gear from the same maker usually travels together. If your order has gear from more than one maker, it can arrive in two or three parcels, sometimes a few days apart. You'll get an email with a tracking number for every parcel, so you always know what's on the way.
Will I pay duty or GST on delivery?
No. Orders under A$1,000 clear into Australia without additional duty or GST, so there's nothing to pay when your parcel arrives.
What if it isn't right?
You have 30 days from delivery to return it unused and in its packaging. If it's faulty or doesn't match what we published, we pay the return postage and refund in full. See Returns.
