- Generous mummy shape maximises thermally efficiency without restricting movement or comfort
- Box-wall baffles give maximum thermal efficiency
- Vertical-V baffling system reduces down migration, keeping it trapped where you need it most
- Differentially cut baffles promote full and complete lofting of down
- Large foot-box reduces down compression while giving enough height for your feet and space to wriggle your toes
- The contoured full hood encloses your head, cinching tight while leaving enough space for your nose and mouth
- Hood and draught tubes baffle integrate to prevent warmth escaping
- A draught tube along the zip insulates the zipper area, keeping warmth in
- Full-length side zip from hood to ankle: a YKK #5 with locking slider and innovative, anti-snag cover
- Selecting a zip side is easy: when lying in a sleeping bag, a left-hand zip (LH) is on your left side
- Joined at the zip: full-length zips allow models with compatible left and right zips to be zipped together
- Hydrophobic Down repels water, helping down stay lofty in all conditions
- Your choice of down: ethically-sourced Hydrophobic Down in either 700-750 loft, or lighter (but just as warm) 800-850 loft
- Water-resistant thread is used to make a durable, well-sealed sleeping bag

WOMEN’S AND MEN’S RATINGS
ISO 23537-1: INDEPENDENTLY TESTED TEMPERATURE RATINGS
All ONE PLANET sleeping bags are temperature rated in accordance with ISO 23537-1. This is the only globally recognised standard for the temperature testing of sleeping bags, and gives ratings for both women and men. Sleeping bags tested to the International Organisation for Standardisation 23537-1 (Requirements for sleeping bags) allow users to make informed, educated and accurate decisions.
The ISO 23537-1 testing methods allows objective comparisons of the warmth of different shapes (mummy, tapered rectangular and rectangular), sizes (small, regular and large) and how this translates into warmth for both women and men. When reading our temperature rating information, the ’Comfort’ rating gives an accurate figure for the lower limit of comfort for a standard woman, while the ‘Limit’ is an accurate gauge of the lowest limit of comfort for a standard man.
Not all manufacturers test to this standard, nor give information about how they arrive at their temperature ratings. As a result, care should be taken when comparing claims of warmth.
