The Cozy 300 is a 220 × 80 cm mummy bag filled with 400 g of white duck down in an 80/20 down-to-feather mix. It weighs 989 g and has a 380T nylon shell, a soft pongee lining, a YKK zip, a drawcord hood and an inside pocket.

The maker rates it comfort 0°C and limit −4°C. We haven't lab-tested it, so we'd suggest it for nights of about +3°C and warmer.

Finally, a bag that fits if you're tall.

Best for
Tall hikers and campers, three-season car camping and hut trips.
Think twice if
80/20 duck down is heavier for the warmth than high-fill goose down. If you're under 185 cm, the Goose Down Mummy Sleeping Bag gives you more warmth choices.
  • 220 cm long

    Most mummy bags stop at about 200 cm. This one suits people up to about 2 m without crushing the footbox.

  • Down mix stated plainly

    400 g of 80/20 white duck down, which is the maker's declared mix, not a vague 'premium down'.

  • Three-season warmth

    The maker rates it comfort 0°C. We'd plan on +3°C and up, then bring a warm mat.

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
  • Cozy 300 Comfortable to about 3°C If you sleep cold, about 8°C

Is it the right bag for your trip?

Pick the coldest night you expect. We'll show every bag and quilt that's warm enough, lightest first, and mark this one if it makes the cut.

How cold will your coldest night be?

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: The maker's figures; our own guide is about +3°C because the rating hasn't been lab-tested. 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.

  • Self-Inflating Camping Mat 10 cm — Foot Pump, Pillow End, 195 × 70 cm, Snaps Into a Double
    10 cm Self-Inflating Camp Mat

    Ten centimetres of air under you and a pillow built in: the car-camping mat that feels like a mattress.

  • Self-Inflating Foam Camp Pillow — 46 × 30 cm, 8–10 cm Loft, 320 g
    Self-Inflating Foam Pillow

    Open the valve and it fills itself: a foam camp pillow that feels like one from home.

  • Down Booties — 700FP Duck Down, Water-Repellent Shell, Non-Slip Sole
    Down Booties

    Warm feet, warm sleep: down booties for camp and the sleeping 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

What does 80/20 mean?
80% of the fill by weight is down clusters and 20% is small feathers. More down clusters means more loft per gram.
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.
