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.
