Solara Emberline Core | Ultralight Down Sleeping Bag | -1°C
Stop choosing between warm and packable.
Bulky sleep systems waste space and still leave you cold. Heavy bags fill your pack up instantly. Cheap down collapses when damp. Most ultralight options feel like a compromise before you've even left the driveway.
The Solara Emberline Core was built to end that argument.
With a -1°C comfort rating, 850FP 90/10 grey goose down and a DWR-treated 20D nylon ripstop shell, the Emberline Core delivers genuine 3-season warmth in a package that disappears into your kit. This is the sleeping bag for all Australian camping, from warm coastal nights to cold highland mornings, for riders, hikers and bikepackers who refuse to carry dead weight.
Built around Adventure riders and Hikers
Most sleeping bags are designed around a 4wd camping brief: flat ground, no condensation, careful handling, and plenty of space in the back of the 4x4. Adventure riders and hikers live differently. Gear gets stuffed into roll bags in the dark. Mornings are damp and busy. You cover big distances over long days and need real recovery, not a shivering night in a bag that's already lost half its loft.
The Emberline Core is engineered for that reality.
The tapered mummy profile locks heat around your core and feet, where you lose it fastest. While the shoulder-width cut gives you room to actually roll over without fighting the bag with the neck baffle retaining your body warmth. It's the geometry most "ultralight" bags skip in the hunt for grams, and it's the difference between waking up rested and waking up sore.
Rolling your sleeping bag up neatly just to fit it in the bag? Sure, but you don't have to with our single piece stuff-sack and compression bag, simply stuff the sleeping bag in the compression sack and pull the straps to compress.
The DWR-treated top shell sheds condensation and light moisture from tent fabric and sleeping pad contact. The 500g of 850FP grey goose down delivers exceptional warmth-to-weight, the same fill spec used in bags retailing for double the price. And with a YKK zipper from collar to shin, there's no snagging, no cold spots, no zip failures 200km from the nearest town.

FAQs
What temperature rating do I actually need for Australian camping?
For most Australian conditions, coastal camping and high country, a bag rated to around 0°C comfort covers you year-round. The Emberline Core is rated to-1°C comfort, which gives you a genuine buffer for cold Victorian mornings, Tasmania, or unexpected cold snaps without overheating in milder conditions.
Down or synthetic - which is better?
Down wins on warmth-to-weight and packability every time. The trade-off used to be moisture, wet down loses loft. The Emberline Core solves that with a DWR-treated 20D ripstop shell that sheds condensation and light moisture before it reaches the fill. For most Australian conditions, DWR-treated down is the right call.
What does fill power actually mean? Is 850FP worth it?
Fill power measures how much loft (and therefore warmth) one gram of down creates. Higher = lighter and more compressible for the same warmth. 850FP is top-tier, the same spec used in bags that often retail for $600–700 AUD. The Emberline Core runs 850FP 90/10 grey goose down, meaning you get fantastic warmth at a fraction of the bulk of lower fill-power alternatives.
How important is packed size for moto camping and hiking?
It's everything. Backpacks, roll bags and frame bags have hard limits, a bulky synthetic bag eats space you need for food, tools and layers. The Emberline Core compresses into its included compression bag to a fraction of the size of equivalent synthetic bags, leaving room in your kit for everything else.
Does the zipper matter?
More than people realise. A snagging zipper at 2am in the cold is genuinely miserable, and a failed zip 200km from the nearest town is a problem. The Emberline Core uses a YKK zipper, the only zipper spec worth trusting for long-term use.
Is one sleeping bag enough for all four seasons in Australia?
For most riders and hikers, yes, if the bag is specced correctly. The Emberline Core's -1°C comfort rating handles everything from warm Queensland nights (unzip and use as a quilt) to cold alpine overnights in Victoria or the Snowy Mountains. One bag, all seasons, no compromise.
How do I know if a sleeping bag will actually fit me?
Length and shoulder width are the two things to check. The Emberline Core measures 220 × 85 × 55 cm, the tapered mummy profile locks in heat at the core and feet, while the wider shoulder cut gives you room to roll over without fighting the bag. An adjustment pull string on the neck baffle allows you to adjust venting and warmth retention. It's built for sleep, not just warmth numbers on a spec sheet.
How long will a sleeping bag last?
A well-made down bag, properly stored and cared for, lasts 10–15 years easily, far outlasting synthetic alternatives that lose loft after a few seasons. Store it uncompressed in a down-storage sack between trips, air it out after each use, and the 850FP down in the Emberline Core will hold its loft for years of hard use.
