The Sonder is a streamlined, practical bag with versatile features, a spacious cut and a lighter build, designed for comfort and warmth year-round. It’s available in three temperature ratings (-3, -5, -8°C ISO 23537-1 limit-of-comfort rating), and small, regular and large sizes. The tapered rectangular shape gives space to move, while the Vertical V-baffle system and draft tube keep warmth where you need it (even as you wriggle around!). The shell is made from durable, water-repellent and highly breathable 10 D Vapour Vent V2 fabric, with a full-length YKK #5 zip and anti-snag locking slider. A separate foot zip allows it to be opened fully to manage warmth.
If you require another size (small or large), wish to upgrade to 800+ loft fill , please call the store during business hours, 03 9555 7811.

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 the 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.
BAFFLE CONSTRUCTION
ONE PLANET baffle technology maximises thermal efficiency. The Vertical-V baffle system uses vertical and V-baffles to keep the 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. ONE PLANET 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 ONE PLANET 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. They'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. ONE PLANET offer two types of premium loft. 700-750 loft Hydrophobic Down is the best value for weight and warmth. 800-850 loft Hydrophobic Down is the premium choice – a must for the gram counters.
ETHICALLY-SOURCED DOWN
Quality threads, twin needles, bar tacks for reinforcement and strength. Non-crack nylon buckles that bend rather than break. Durable, chunky YKK zips. The water-resistant webbing used on load-carrying straps means you won’t be given the slip. ONE PLANET consider every detail, creating big differences in use.
FILLED IN MELBOURNE
ONE PLANET down sleeping bags are hand-filled to order, in their Melbourne factory – usually the day after the order is placed! ONE PLANET have been filling their sleeping bags in Australia for more than 40 years: it’s the best way to ensure premium-quality, freshly-made bags. They can personally embroider every stuff sack.
DESIGN PHILOSOPHY
ONE PLANET design innovations have led the way since 1980, both locally and globally. ONE PLANET 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 females and males 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.
