The Nitrous sleeping bag is designed for superior performance in summer or shoulder seasons: it is the perfect bag when every gram counts. It’s available in three sizes (small, regular and large) and has a temperature rating of -3/+3°C (lower limit of comfort for males/females; tested in accordance with ISO 23537-1). The Nitrous has a generous tapered rectangular shape and box foot, but remains incredibly compact, filled with 800-850 loft non-PFC hydrophobic down with a box wall baffle construction. The shell fabric is 10 D Vapour Vent (V2) fabric – lightweight and downproof by construction – which offers excellent breathability, comfort and non-PFC water repellence. The full-length YKK #5 locking zip has an anti-snag slider and opens at both ends, allowing extra ventilation. Baffle ConstructionONE PLANET baffle technology maximises thermal efficiency. The 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. ZipsEvery 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 V2The Vapour Vent (V2) fabrics are lightweight, breathable nylon with non-PFC 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 DownAll ONE PLANET down has been treated with a non-PFC hydrophobic water-repellency application. This causes the down to repel water rather than absorb it, minimising clumping and helping the down 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 multi-day journeys or in wet conditions. Down DistributionIn ONE PLANET Nitrous 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 LoftWe use 800-850 loft non-PFC hydrophobic down – our premium choice and a must for the gram counters. The quality of down used in a Nitrous sleeping bag makes a huge difference to its warmth, weight, durability and compactness, as well as the loft recovery of the down. We use the best down available, ensuring that our bags are warmer and more compact than similar weight bags that use inferior fill. Because what adventurer doesn’t want a warmer, smaller bag? Ethically-Sourced DownONE PLANET takes seriously its responsibility to uphold the highest standards of animal welfare. Our down is gathered in a way that meets our strict ethical and quality standards, and it’s 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). There is no chance of cross contamination as we fill the bags in our Melbourne factory with our own audited batches of down. Filled In MelbourneEach ONE PLANET Nitrous sleeping bag is hand-filled to order in our Melbourne factory, usually the day after the order is placed! 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 PhilosophyOur 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 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. Features The Nitrous sleeping bag has a generous box foot that maximises thermal efficiency without restricting movement or comfort Vertical V baffle system reduces down migration, keeping it trapped where you need it most Differentially cut baffles promote full and complete lofting of down The Nitrous shell is made from 10-denier Vapour Vent (V2), which is downproof by construction, highly breathable, and has non-PFC water-repellent treatment Large foot-box reduces down compression while giving enough height for your feet and space to wriggle your toes Three-quarter hood is contoured to cover your head comfortably and effectively A draught tube along the zip insulates the zip area, keeping warmth in A full-length side zip runs from hood to ankle. It’s a YKK #5 (a durable, reliable zipper) with locking slider, so if you half zip the bag, it won’t unzip as you wriggle and roll. The innovative, anti-snag cover prevents the zip catching Joined at the zip: full-length zips allow models with compatible left and right zips to be zipped together Non-PFC hydrophobic down repels water, helping down stay lofty in all conditions Bags hand-filled with ethically-sourced, ultralight 800-850 loft, non-PFC hydrophobic down Specs Intended use: lightweight bushwalking, bike/backpacking Temperature rating: independently tested in accordance with ISO 23537-1 Available sizes: small, regular, large Shape: tapered rectangular with box foot Baffle construction: Vertical V baffle system (vertical/V baffles) with box wall construction Zip: YKK #5 with locking slider and anti-snag cover Zip configuration: full-length zip Zip side: small has RH zip; regular has RH or LH zips; large has LH zip.

ISO 23537-1 temperature testing gives a temperature limit at which a ‘standard male’ or ‘standard female’ will sleep in thermal equilibrium (have a comfortable night’s sleep). Both are based on a fit and healthy 25-year-old. If you’re older or younger, you may sleep colder than the ‘standard’, so we would recommend considering a warmer bag. Your other equipment (sleeping mat, pillow, tent style), the environment (weather, location) and your biology can affect your warmth during the night. The Importance Of Independent ISO-23537-1 Testing Each ONE PLANET Nitrous sleeping bag is temperature rated in accordance with the International Organisation for Standardisation 23537-1 (Requirements for sleeping bags). This is the only globally-recognised standard for the temperature testing of sleeping bags, and gives ratings for both females and males. Testing sleeping bags to ISO 23527-1 allows users to make informed, educated and accurate decisions. The ISO 23537-1 testing methods allows objective comparisons of the warmth of different shapes (box and zipped foot), sizes (small, regular and large), fill quality (synthetic fill, 700+ and 800+ loft down), construction and design. Not all manufacturers test to this standard, nor do they give information about how they arrive at their temperature ratings. As a result, care should be taken when comparing claims of warmth.
