Choose by your coldest night

Pick the coldest night you're likely to face, not the average one, and we'll show every bag and quilt that's warm enough. When you're not sure, go warmer: a bag that's too warm, you unzip; a bag that's too cold can't be fixed on the mountain.

bags and quilts are warm enough. They're sorted lightest first, so the top one is the lightest that will do the job.

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.

Three bags for a cold Australian night

Same job, three price points. Every figure comes from the maker's own published specification, including the ones that don't flatter us.

Where Sea to Summit wins: their rating is independently lab-tested to EN/ISO 23537, and their bag is 305 g lighter. If you're counting grams for a multi-day traverse, buy theirs. Where the Z700 wins: 700 g of 800+ fill-power down against their 430 g, for A$416 less. What we won't do is quote you a lab rating nobody has paid for.

Three numbers, in this order

Most listings lead with a temperature and a price. Those are the two least reliable numbers on the page. Read these first.

  1. 1

    Fill weight: grams of down

    How much insulation is actually in the bag. A listing that hides it is hiding the cost of the product. As a rough guide for Australia: 400–500 g is a summer-to-shoulder bag, around 700 g takes you below freezing, and 1,000 g is for snow.

  2. 2

    Fill power: 700, 800, 850

    The quality of the down: how much it lofts per gram. Higher fill power gives the same warmth for less weight and a smaller pack. It doesn't mean warmer on its own: 300 g of 800FP down is still a summer bag.

  3. 3

    Total weight and packed size

    What you actually carry. Compare it with the fill weight: a bag with 700 g of down that weighs 970 g is spending 270 g on fabric and zips, which is about right for a 10D shell.

Temperature ratings come last, and only once you know who measured them. EN/ISO 23537 means an independent lab test. Every rating in this shop is the maker's own: Aegismax says it follows the EN 13537 method, and Black Ice and Naturehike don't say. The FAQ has the long version.
