- Generous mummy shape maximises thermally efficiency without restricting movement or comfort
- Box-wall baffles give maximum thermal efficiency
- Vertical-horizontal-vertical baffling blocks the migration of down, keeping it trapped where you need it most
- Differentially cut baffles promote full and complete lofting of down
- Elasticated horizontal baffles reduce down migration and ensure warmth stays trapped against the body, minimising unintended venting
- Large foot-box reduces down compression while giving enough height for your feet and space to wriggle your toes
- The contoured hood encloses your head, cinching tight while leaving enough space for your nose and mouth
- The elasticised 3D neck baffle effectively traps warmth around the neck and shoulders
- Two draught tubes (top and bottom) insulate the side zipper
- An external hood baffle cuts wind keeping your face and nose protected
- 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

FEMALE AND MALE 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 females and males. 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 females and males. When reading our temperature rating information, the ’Comfort’ rating gives an accurate figure for the lower limit of comfort for a standard female, while the ‘Limit’ is an accurate gauge of the lowest limit of comfort for a standard male.
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.
ONE PLANET baffle technology maximises thermal efficiency.
The vertical baffle system uses vertical and horizontal chambers to keep lofty down in the right spot, regardless of night-time manoeuvres. Box wall baffles connect the outer shell and internal fabric, creating 3D chambers that promote lofting, aid even insulation and stop draughts. The differential cut also assists lofting: the internal fabric is cut narrower than the outer shell, making the bag’s inner circumference smaller than its outer.
Every detail counts. We use YKK #5 locking zips with an anti-snag slider. The anti-snag covers make jamming zips a thing of the past, while the YKK #5 zip is more reliable, durable and lasts longer than lower-gauge zips.
Using a locking slider stops the zip from creeping open, so it will stay where you want it to for a good night’s sleep.
• PERTEX Quantum Pro
Pertex Quantum Pro efficiently manages moisture whilst providing essential weather protection. This lightweight durable fabric is an ideal choice for multiday, alpine or condensation rich adventures.The fabric combines a highly breathable microporus coating with a super-durable face fabric and is 100% windproof. Weighting a measly 36 g/m2, it has a 1000 mm waterhead and legendary breathability: 7000 g/m2/24 hours (JIS L 1099 A-1 testing). You do the comparisons: it’s hard to beat!
All ONE PLANET down has been treated with a hydrophobic water repellency application. This causes the down to repel water rather than absorb it, minimising clumping and helping the down in your sleeping bag stay dry and lofty.
Hydrophobic Down allows your sleeping bag to dry quicker and stay warm for longer, and is especially important for bags used on multiday journeys or in wet conditions.
In ONE PLANET sleeping bags, 55 per cent of the down fill is on the top and 45 per cent is on the bag’s base. We’ve selected this distribution of down after carefully considering how real people move and sleep – after all, we want it to work in real life! This down distribution ensures you stay warm in every position, preventing a cold back as you roll, wriggle and move.
The quality of down used in a sleeping bag makes a huge difference to its warmth, weight, durability and compactness, as well as the loft recovery of the fill. We offer two types of premium loft.
700-750 loft Hydrophobic Down is our best value for weight and warmth.
800-850 loft Hydrophobic Down is our premium choice – a must for the gram counters.
ONE PLANET takes its responsibility to uphold the highest standards of animal welfare seriously. Our down is gathered in a way that meets our strict ethical and quality standards, and is sourced as a by-product from the food and meat industry. We source from certified facilities and audit with the IDFL (International Down and Feather Laboratory). In our Melbourne factory we hold only our own audited batches of down: there is no chance of cross contamination.
