Size

The Cocoon has one of the best warmth-to-weight ratios in our range, making it a popular choice for the lightweight adventurer. The sumptuous, highly breathable 10-denier Vapour Vent is used as both inner and outer fabric; it’s a real weight saver, as is the body-hugging mummy shape. Your down won’t be going anywhere thanks to the combination of vertical chest baffles and our famous V-baffles, while the hood and neck closure stop your warmth escaping. The flexibility of a full-length zip helps your night time metamorphosis into a well-rested, happy little camper.

Temp Ratings

One Planet sleeping bags are rated using the international standard for sleeping bag performance, ISO 23537-1. (This is a revised version of European Standard EN 13537.) 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 ISO 23537-1, ‘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.

Ethically sourced down
Our 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.

Quality bag!

After a few years of going down a review rabbit hole I finally made a purchase and chose a One Planet bag and it is excellent! Incredibly warm and lofty and packs down tight. I’m stoked with this purchase and can’t wait to put it to test against the elements that hunting in NZ has to offer.

Great sleeping bag

Feels very warm as it should. Good size and fit and the weight was spot on. About to take it on a week in the southern alps!

Great bag

High amount of loft but stuffs small into its stuff sack. I'm 180cm tall and it's a good length for me and my Nemo Fillo to fit inside. One Planet's mummy shape is more spacious than Rab's which is a plus. Zips don't snag. Only issue is I'm too hot (but it's coming into summer so that's expected for a -11 bag)
