One Planet is an Australian brand making some of the Southern Hemisphere's finest sleeping bags and outdoor gear. Designed for the demanding conditions of the Australian and NZ backcountry — high moisture, variable temperatures, and multi-day use — One Planet's sleeping bags are a benchmark for quality in this part of the world.
Why Buy One Planet from Dwights?
Dwights is an authorised One Planet dealer in New Zealand — genuine product backed by the full manufacturer warranty. We carry NZ-stocked One Planet sleeping bags with fast delivery and can help you choose the right temperature rating and bag shape for your trips.
One Planet is an Australian outdoor brand that has been designing and manufacturing sleeping bags and packs specifically for the conditions of the southern hemisphere for over three decades. Rather than adapting gear designed for northern hemisphere markets, One Planet builds from the ground up with the damp, variable climates of Australia and New Zealand in mind. At Dwights, we stock three of their key sleeping bag series — the Nitrous, Sonder, and Cocoon — covering everything from ultralight Great Walk trips to serious alpine expeditions. One Planet bags are consistently among our top recommendations for NZ tramping sleeping bags. Browse the full sleeping bags collection to compare models.
One Planet Nitrous Series — Ultralight Tramping Bags
The One Planet Nitrous series is designed for trampers who take weight seriously. Using premium down fill in a lean, packable construction, the Nitrous range delivers genuine warmth at a pack weight and size that makes a real difference over a multi-day tramp. It's one of Dwights' lead recommendations for Great Walk trampers who want to keep their pack light without compromising on a good night's sleep.
One Planet Sonder Series — Versatile 3-Season to Cold Weather
The One Planet Sonder series is our other lead recommendation for NZ tramping. Covering 3-season through to cold-weather use, the Sonder is an all-round sleeping bag built for the range of conditions NZ tracks throw at you — from mild summer nights on the Abel Tasman to cold alpine hut overnights on the Routeburn or Kepler. It strikes a well-judged balance between warmth, weight, and packability that suits the majority of NZ trampers.
One Planet Cocoon Series — Premium Alpine Down
The One Planet Cocoon series sits at the top of the range, designed for serious cold-weather and alpine use. With higher fill weights and a premium construction aimed at demanding mountain environments, the Cocoon is the choice for trampers pushing into winter alpine terrain or extended cold-weather expeditions where there's no margin for an underpowered sleeping bag.
Frequently Asked Questions — One Planet
What One Planet sleeping bags does Dwights stock?
Dwights stocks three series from One Planet: the Nitrous series (ultralight tramping sleeping bags designed for weight-conscious trampers), the Sonder series (a versatile 3-season to cold-weather range well-suited to NZ conditions), and the Cocoon series (premium alpine down sleeping bags for cold-weather and high-altitude use). The Sonder and Nitrous series are our lead recommendations for NZ tramping and Great Walk trips.
What's the difference between One Planet Nitrous, Sonder and Cocoon sleeping bags?
The One Planet Nitrous series is built for minimum weight — it uses high-quality down and a streamlined design to deliver warmth at the lowest possible pack weight, making it ideal for trampers counting every gram. The Sonder series takes a more all-round approach, covering a range from 3-season use through to cold weather, with a construction balance between warmth, weight, and packability that suits most NZ tramping conditions well. The Cocoon series is the premium end of the range — designed for serious alpine and cold-weather use, with higher fill weights and a more robust construction aimed at demanding mountain environments. For most NZ trampers, the Sonder or Nitrous will be the right fit.
Which One Planet sleeping bag is right for NZ Great Walks?
For NZ Great Walks, the One Planet Sonder and Nitrous series are the two top picks at Dwights. The Sonder is an excellent all-rounder — it covers the temperature range you're likely to encounter across tracks like the Routeburn, Milford, or Kepler, where hut temperatures can drop significantly overnight even in summer. The Nitrous is the lighter option for trampers who want to minimise pack weight, particularly on well-served Great Walks with hut accommodation where you're not carrying a tent or heavy camp gear. If you're doing the Abel Tasman in summer and want something light, the Nitrous suits well; for the southern alpine Great Walks with cold overnight temperatures, the Sonder provides more confidence.
Are One Planet sleeping bags good for NZ conditions?
One Planet is an Australian brand that designs its gear specifically for southern hemisphere conditions, including the high humidity, variable temperatures, and wet environments typical of NZ tramping. This makes their sleeping bags a particularly good fit for New Zealand use — they're not designed around the cold-dry conditions of northern hemisphere alpine environments but rather the damp, changeable weather NZ trampers encounter on tracks from Northland to Fiordland. The down fill in One Planet bags is selected with moisture management in mind, and the cut and construction reflect real-world southern hemisphere tramping use.
How do I store and care for a One Planet sleeping bag?
When not in use, store your One Planet sleeping bag uncompressed in the large mesh storage sack provided — never leave it packed in its compression stuff sack for extended periods, as prolonged compression can affect the down's loft and insulating performance over time. Store it in a cool, dry location out of direct sunlight. To wash, use a front-loading machine on a gentle, warm cycle with a down-specific cleaner; avoid regular detergents which can strip the natural oils from down. Tumble dry on low heat with dryer balls to restore loft, and ensure the bag is completely dry before storing. Air the bag out after each trip before packing it away.
