One Planet Bush Lite

The Bush Lite combines the ultimate in four-season warmth and weather protection with the luxury of more space. There’s a bag to suit everyone: they’re available in three sizes (small, regular and large) and two temperatures (lower limit of comfort for males/females -15/-8°C, -19/-11°C, all independently tested in accordance with ISO 23537-1). The Bush Lite is filled with ultra light and compressible 800-850 loft non-PFC hydrophobic down, while the vertical baffle system ensures maximum warmth for weight. The shell is made from water-resistant, breathable Pertex Quantum Pro, giving top-end durability, breathability and water resistance at minimum weight. This roomy bag gives more wriggle room. For durability and function, the full-length zip is a YKK #5 with anti-snag cover, with a separate foot zip so you can open it fully.

Baffle Construction
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.

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.

Pertex Quantum Pro
ONE PLANET uses waterproof, breathable and windproof Pertex Quantum Pro fabric as the outer shell of alpine and winter sleeping bags. This lightweight material is awesome at managing moisture and maximising loft, providing essential weather protection and amplifying performance, making it an ideal choice for multi-day, alpine or condensation-rich adventures. The fabric combines a highly breathable microporous coating with a durable face fabric and is 100% windproof and waterproof, with high breathability.

Hydrophobic Down
All 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 Distribution
In ONE PLANET Bush Lite 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
We 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 Bush Lite 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 Down
ONE 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 Melbourne
Each ONE PLANET Bush Lite 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 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 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

• Tapered rectangular shape and zipped foot give versatility and roomy comfort to the Bungle sleeping bag
• The vertical baffle system (vertical-horizontal-vertical baffles) blocks the migration of down, keeping it where you need it most
• Differentially cut baffles promote full and complete lofting of down
• Waterproof, breathable and windproof Pertex Quantum Pro fabric is used for the outer shell of the Bush Lite. This lightweight material is an ideal choice for multi-day, alpine or condensation-rich adventures
• The inner is made from 10-denier Vapour Vent (V2), which is downproof by construction, highly breathable, and has non-PFC water-repellent treatment
• The half-moon foot-box is wide and cosy, while base draft tubes keep you warm and toasty
• 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
• 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
• The independent foot zip runs from ankle to ankle and can be fully opened for extra ventilation. The two zips meet above the ankle, with a 10 centimetre crossover to keep draughts out
• Two draught tubes (top and bottom) insulate the side and foot zip
• 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

How Warm Will I Be?

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 Bush Lite 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.
