One Planet Winter Lite -12°C Down Sleeping Bag

The Winter Lite is the most thermally-efficient shell One Planet makes with a water-resistant outer – a must for anyone heading above the snowline. The mummy shape hugs the body, eliminating dead space, whilst the vertical baffles stop unintentional down movement over the course of the night. Super breathable, water resistant Pertex Endurance forms the outer, and the inner is made from sexy, silky and lightweight 15-denier Vapour Vent. Features a three-dimensional neck muff which helps keep your warm air in.

Fabric

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 in One Planet's range. 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.

Down

One Planet use two qualities of down in their sleeping bag range.

700+ loft DWR-treated duck down is our 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 our 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

Winter Lite sleeping bags are filled to order with 700+ loft DWR DOWN for great value and 800+ loft DWR DOWN for greater weight savings.

Temperature Ratings

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.

Sizing

Winter Lite sleeping bags come in two sizes.

As a general rule, One Planet 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, One Planet offer a series of Sleeping Bag Expanders.
