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.

Great bit of kit

Love the Cocoon, best value and great performance. I use mine unzipped in huts and mostly in a two person tent. I'm warmer than average so it's been fine through North Island winter.

Sleeping Bag

This bag is great - I have only used it on one trip so far, where I stayed in huts, so haven't tested it to low temperatures. But is is very comfy, zips and covers, hood etc all work well and most importantly it packs down to very little and weighs virtually nothing!

Winter, no problem

Very warm indeed, I was thinking how was this light thing going to keep me warm in the snow. Should neva have doubt it because I was super warm at -4 with only light sleep wear. Recommended to every one outdoors in winter.
