One Planet Bush Lite -11°C Down Sleeping Bag
A One Planet classic, this tapered rectangular bag sets the standard for bushwalking. The vertical baffle system reduces the movement of air and down, preventing cold spots, while the more relaxed fit adds wriggle room and versatility. The Pertex Endurance shell is brilliant in damp conditions, providing excellent breathability and water resistance at minimum weight. An inner of highly breathable, 15-denier Vapour Vent fabric saves weight and adds luxury, as does the 3D neck muff.
Sleeping bag fabric must perform two roles: keep the fill in the bag and allow body-generated moisture to get out. The shell fabric must also keep external moisture out in some conditions; in bags designed for extreme use, highly water-resistant shell fabric is preferable.
Pertex Endurance is the lightest, most breathable and weather-resistant fabric we can find. It weighs a measly 36 g/m2, has a water head of 1000 millimetres and a breathability of 7000 g/m2/24 hours (according to results from test JIS L 1099 A-1). You do the comparisons: it’s hard to beat! The fabric combines an air-permeable membrane with a durable nylon face fabric: the membrane is so thin it barely affects the weight or softness of the material, but it is highly breathable and water and wind resistant.
One Planet DWR Down
One Planet use two qualities of down in our sleeping bag range.
700+ loft DWR treated duck down is the best value down, used for applications where minimum weight and packed size are not critical. Sleeping bags filled with this down are around $50 cheaper than their 800+ loft counterparts and around 100 grams heavier.
800+ loft DWR treated duck down is the premium choice – a must for the gram counters. This high-lofting white duck down delivers luxurious warmth at a fine feathery weight. This down has excellent compactability and loft recovery.
Down is the best insulation for lightweight sleeping bags due to its loft, compressibility and durability. However, this golden fibre has a failing: its ability to insulate drastically decreases when it is wet.
The solution is now here – DWR DOWN. This down has been selected to meet our rigorous standards, with a durable water-repellent (DWR) treatment applied after the cleaning and sorting process.
The benefits of DWR DOWN are:
It absorbs less water in damp conditions
It retains higher loft (insulation) in damp conditions
It dries faster
Bush Lite sleeping bags are filled to order with 700+ loft DWR Down for great value and 800+ loft DWR Down for greater weight saving.

One Planet sleeping bags are rated using the European Standard EN13537, with every bag given three ratings: two ‘real world’ and one extreme.
- ‘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 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.
Bush Lite sleeping bags come in two sizes. As a general rule One Planet sleeping bags are a little roomier than other brands.
A well-fitting bag will give the best performance. If you need more room, check out the One Planet Sleeping Bag Expanders.
