Winter Lite -9
If you are a warm sleeper, wear clothes to bed or need a lightweight bag for high performance in more moderate conditions, then check out the Winter Lite -9. This is the most thermally-efficient shell with a water-resistant outer in the One Planet range.
The mummy shape hugs the body, eliminating dead space.
Vertical baffles stop unintentional down movement over the course of the night.
Super breathable, water-resistant Pertex® Endurance forms the outer.
Filled with One Planet's water-repellent DWR DOWN; choose between 700+ or 800+ loft.
The inner is made from sexy, silky and lightweight 15-denier Vapour Vent.
Three-dimensional hood and foot increase comfort and warmth.
The 3D neck muff and twin draft tubes on the zip keep warm air in.
The removable pillow slip solves the ‘camping pillow’ dilemma.
Available in small, regular and large sizes.

One Planet DWR DOWN
Down is the best insulation for lightweight camping gear 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.
One Planet offers a choice between 700+ and 800+ loft down
This gives our customers more choice regarding weight and price. Higher loft down provides better insulation so less filling is required, but it is more expensive. Lower loft down is less expensive, but more filling is required to achieve the same temperature rating. We leave the decision to you.
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.)
An ultralight, 15-denier nylon used to make light, high-performance bags. Used on our Booster, Cocoon and Zephyr bags, as well as the inner on the Bush Lite and Winter Lite, it offers the ultimate in luxury and warmth-to-weight ratios.
The Winter Lite and Bush Lite are designed for extreme conditions, so we have chosen their shell fabric accordingly. 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.
