One Planet Cocoon Mummy Sleeping Bag

The Cocoon has one of the best warmth-to-weight ratios in One Planet's 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.
