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.

BAFFLE CONSTRUCTION

ONE PLANET baffle technology maximises thermal efficiency.

Vertical-V baffle system uses vertical and V-baffles to keep our lofty down in its precise location, no matter how you wriggle and roll. 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.

ZIPS

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.

VAPOUR VENT V2

The Vapour Vent (V2) fabrics are lightweight, breathable nylon with C0 environmentally-friendly water-repellent treatment that promotes hands-free moisture management.

The smooth fabrics are light and warm to the touch, ideal for use on multi-day journeys. The tight weave and high thread count ensures they are ‘downproof by construction’. The majority of our bags use the silky, light, 10-denier version both inside and out, while some use the more durable 20-denier option.

HYDROPHOBIC DOWN

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.

DOWN DISTRIBUTION

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.

PREMIUM LOFT

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.

ETHICALLY-SOURCED DOWN

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.

MADE IN MELBOURNE

Every ONE PLANET sleeping bag is hand-filled to order in our Melbourne factory. We’ve been filling our sleeping bags in Australia for more than 40 years: it’s the best way to ensure premium-quality, freshly-made bags.

We can personally embroider every stuff sack. It brings us great joy to make your bag as unique as you are.

DESIGN PHILOSOPHY

Our design innovations have led the way since 1980, both locally and globally. Our sleeping bags are designed after careful consideration of real sleep – how we lie, move and lose warmth – and real people, with ranges made to fit women and men of all shapes and sizes.

ONE PLANET sleeping bags combine 40 years of manufacturing experience with world-leading materials, modern scientific testing and the passion to keep improving.
