*Many One Planet sleeping bags are made to order in their Melbourne factory! - Orders of these bags may take 7-10 business days to arrive in store*



This bag is as versatile as they come: it makes a fantastic touring bag as it’s small, light (less than a kilogram!) and comfortable. 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. The Down Under is perfect for climates from the frosty south to the balmy north, with a comfort rating ranging from 2ºC to 9ºC depending upon which side is on top.

Tapered rectangular shape gives extra room and versatility.
Light, compact and durable Thermolink fill.
Uses strong, highly breathable 30-denier Vapour Vent for inner and outer fabric.
Three-dimensional hood and foot increase comfort and warmth.
Bi-directional zips allow you to vent your feet or zip the bag to others in the One Planet range.
Available in regular size only.

Thermolink fill

All One Planet synthetic bags use Thermolink, our new fabulous fill. This gives a massive 15 per cent increase in warmth when tested to the European standard, meaning we can make our bags 200-300 grams lighter. Thermolink is a bonded fibre, with the fibre blanket linked throughout its thickness. This makes it strong and eliminates the need for sewn-through stitching, as well as the accompanying heat loss.

The synthetic range is made in China due to manufacturing constraints in the Melbourne factory.

Additional information from manufacturer


Sleeping bag fabric must perform a number of roles: keep the fill in the bag; allow body generated moisture to get out; and the shell fabric must also keep external moisture out in some conditions.

Fabrics that are ‘downproof by construction’ are ideal as they don’t use coatings which can reduce breathability: instead, the very tight weave prevents down from escaping.

Vapour Vent (V2)

Vapour Vent (V2) is used as the inner in all One Planet sleeping bags and as the shell for most. This durable, tightly-woven fabric is ‘downproof by construction’: the weave is so tight down cannot escape through the cloth. Coatings are not required, so body vapour can vent through the fabric more effectively, reducing moisture build-up in the down and allowing it to loft to its full potential. We use three weights of the silky V2 fabric, differentiated by their denier. (The fineness of thread is measured in denier: the finer the thread, the lower the denier and the lighter, more silky and expensive the fabric.)

This 30 denier nylon makes a good, all-round shell. It is used as the inner and outer fabric on the Bungle and Robin Hoodless, while a non-downproof version of V2-30 is used in our synthetic range.
