This bag is as versatile as they come. There is more fill on one side than the other so you can adjust its warmth by flipping it over. The hood can be fastened to whichever side you want – it’s attached with a hook-and-loop closure. This tapered rectangular bag can be completely unzipped and it weighs less than a kilogram. The Down Under is perfect for climates from the frosty south to the balmy north, with a comfort rating ranging from 2°C to 9°C depending upon which side is on top.
One Planet sleeping bags are rated using the European Standard EN13537. This means every sleeping bag has two ‘real world’ and one extreme rating. To determine what temperature might be most suitable for you see our technical pages.
‘Comfort’ rating is based on a ‘standard’ woman having a comfortable night’s sleep.
‘Limit of comfort’ is based on the lowest temperature at which a ‘standard’ man is deemed to be able to have a comfortable night’s sleep. This is the figure we use in our product descriptions.
‘Extreme’ rating is a survival rating for a ‘standard’ woman. According to EN 13537, ‘a strong sensation of cold has to be expected and there is a risk of health damage due to hypothermia’. This is a survival rating only, and consumers should not rely on this rating for general use. The best guidelines are the comfort and limit of comfort ratings.
Down Under sleeping bags come in one size.
As a general rule, our sleeping bags are a little roomier than other brands. The shoulder circumference measurements (below) give an indication of the internal space in the sleeping bag.
A well-fitting bag will give the best performance. If you need more room, we offer a series of Sleeping Bag Expanders.
This bonded fibre weighs less and packs down smaller than competing synthetic fills, making our bags lighter and more compact while maintaining comfort and durability. The secret is in the manufacturing process: thousands of hollow fibres are sandwiched between a high-density thermal barrier and a fine, soft, body-conforming radiant retention layer to form one continuous sheet of Thermolink fibre. As it is one continuous layer, there aren’t any gaps for heat to escape, leading to better performance than traditional baffled fills.
Down Under sleeping bags are made using lightweight and highly breathable 20-denier Vapour Vent fabric. This strong, compressible and highly breathable fabric uses a tight weave that keeps the insulation in but allows water vapour to escape. This reduces the possibility of clamminess and allows the insulation to loft fully for maximum performance.
Storage and stuff sacks
Your sleeping bag is delivered in a compression stuff sack, as this is easiest way to transport it. However, it should not be stored in its stuff sack long-term as this compresses the fill material and may cause damage. Hang the bag in your wardrobe over a large hanger, in the supplied storage bag or an old pillowslip, or flat under your bed.
When putting your sleeping bag in its stuff sack, do as its name suggests! Don’t roll or fold it, simply stuff it in with your fist, pushing it down to the bottom of the sack. This allows the fill to settle in pockets rather than being squashed flat.
Be careful not to place excessive force on the compression straps. Compress the bag first, then tighten the straps.
Don’t over-compress your sleeping bag. If the bag is compressed too much, for too long, it is possible to permanently damage the fill material, resulting in an inferior performance.
Cleaning your bag
Washing a sleeping bag can be a daunting process. However, your bag will perform better for longer if it is kept clean. There are two ways to do this:
Use a professional
This is the easiest way to get your bag clean. One Planet don’t just make the bags, we look after them, too. Send your dirty, bedraggled bag to us and it will come back fresh, clean and fluffy. Too easy! Contact One Planet by email or phone for further details on our services.
If using another professional service, ensure they specialise in cleaning sleeping bags.
DIY sleeping bag washing
You will need a front-loading washing machine to wash your synthetic sleeping bag carefully. A machine designed for domestic use is fine for washing a single sleeping bag.
Clean out the machine’s soap dispenser to remove any soap residue.
Undo the zippers on the sleeping bag.
Load your sleeping bag into the machine.
Use Nikwax Tech Wash. (Follow directions on pack.)
Select a normal wash at 40°C with a spin of 700 RPM and an extra rinse cycle.
Carefully remove your bag from the washing machine.
Dry the sleeping bag on a line in the shade – it will take a few days.
Finish the process by tumble-drying your bag for 30 minutes on low heat. (It is very important to keep the temperature low – otherwise you will bake your bag!)
