One Planet Quest Zero Quilt

The Quest Zero is a box-walled version of the Quest quilt. Built with One Planet’s famous design considerations and care, it uses 15-denier Vapour Vent V2 and 800-850 loft Hydrophobic Down, with box-wall baffles constructed into vertical V-baffles for efficiency and weight savings. This wonderful ultralight sleep system packs up small, fitting into a 2.5 litre stuff sack.

In cooler weather, the Quest Zero is to sleeping bags what (really light!) thermals are to layering, combining with all new One Planet bags for warmth in a huge range of temperatures while adding very little weight. The Quest Zero attaches inside these bags easily and securely on either side of zip, allowing you to pick and choose your bags to suit the conditions. Available in regular or large sizes.

Fabric

Quest quilts are made using lightweight and highly breathable 15-denier Vapour Vent fabric. This strong, compressible and highly breathable fabric is ‘downproof by construction’: the tight weave keeps the down in but allows water vapour to escape. This reduces the possibility of clamminess and allows the down to loft fully for maximum performance.

Down

One Planet use two qualities of down in their sleeping bag range. The Quest Zero quilts are filled to order with the higher quality 800+ loft DWR DOWN.

700+ loft DWR-treated duck down is One Planet's 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:

Ethically sourced down

One Planet's down is ethically sourced, harvested and cleaned before purchase, with both the down and our supplier passing independent International Down and Feather Laboratory (IDFL) audits relating to ethical traceability. This means that the white down and feathers we purchase are from animals that haven’t been live plucked or force-fed at any point during the supply chain.

The IDFL has been around almost 40 years and has a solid base in China, from where around 75% of the global supply of down is sourced. There are more details on the IDFL here: www.idfl.com/whytest

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

Quest sleeping quilts and Nitrous 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, we offer a series of Sleeping Bag Expanders.
