Goose down that shrugs off condensation.
- Best for
- Hikers who want goose-down warmth with less weight and bulk.
- Think twice if
- 10D fabric is fine and light, so treat it gently around sharp gear and campfire sparks.
Water-repellent down
Treated down keeps more of its loft when the tent's damp inside.
10D shell
A fine, light fabric that packs smaller than 20D or 400T shells.
Vents and converts
Open the foot zip on warm nights, or unzip it all the way into a quilt.
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- 10D goose 400 g Comfortable to about 8°C If you sleep cold, about 13°C
- 10D goose 700 g Comfortable to about 2°C If you sleep cold, about 7°C
- 10D goose 1000 g Comfortable to about −5°C If you sleep cold, about 0°C
- 10D goose 1300 g Comfortable to about −9°C If you sleep cold, about −4°C

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.
Which one?
| Down fill | Bag weight | Comfortable to (our guide) | Price |

| 400 g | 800 g | +8°C | A$369 |
| 700 g | 1,100 g | +2°C | A$449 |
| 1,000 g | 1,400 g | −5°C | A$549 |

The numbers
Taken from the maker's own listing and spec cards for this exact model; anything marked our guide is ours. Where the maker doesn't publish something, the line is left out rather than guessed.

“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 LinerThe cheapest way to make a down bag last longer: sleep in this, wash this.
-
Inflatable Pad With PillowA cushioned air pad with its own pillow and a built-in pump. No puffing, no separate pillow to pack.
-
Compression Stuff SackSquash your sleeping bag to half its size with four straps.
-
Dry Bag Set of 5Five small roll-top bags that keep the important things dry and easy to find.
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.
