Down vs Synthetic—What’s Right for You?
Choosing between down and synthetic sleeping bags largely comes down to your priorities and the conditions you’ll be camping in. Down bags are incredibly warm, lightweight, and pack down small—ideal for hikers and backpackers—but they’re pricey and don’t perform well when wet. Synthetic bags, by contrast, are bulkier but more affordable and still keep you warm in damp conditions. If you’re camping in unpredictable Aussie weather or on a tighter budget, synthetic may be the smarter choice.
How to Choose the Right Temperature Rating
Not all sleeping bags are created equal when it comes to warmth. Ratings are standardised under the ISO 23537-1:2022 system, which breaks temperatures into three zones:
Comfort – the lowest temperature at which the average person sleeps comfortably.
Lower limit – the coldest temperature for a standard male to sleep for 8 hours curled up.
Extreme – survival-only rating; not recommended for regular use.
In Australia, a summer trip up the coast might only need a comfort rating of 5–10 °C, while camping in the High Country or Tassie in winter calls for a bag rated 0 °C or colder.
Bag Shapes & Fit
Sleeping bags come in various shapes to suit different comfort levels and warmth needs. Mummy bags are tapered to retain heat and are best in cold conditions, while rectangular bags are great for warmer weather and anyone who likes to stretch out. Barrel-shaped bags offer a middle ground—more spacious than mummy styles but still fairly heat-efficient. For couples, double sleeping bags add a bit of coziness (though at the cost of warmth), and ultralight adventurers might opt for an elephant’s foot style for reduced weight and space.
Key Features to Look For
When comparing bags, a few features can really elevate your experience. Look for draft tubes and collars that seal out cold air, adjustable hoods for extra warmth, and water-resistant outer shells that add durability. Compression sacks are vital for bushwalkers who need to save space, and stash pockets, two-way zippers, and tailored sizing can all make your sleep setup more convenient and comfortable.

Whether you’re just starting out or upgrading your gear, Anaconda has it all. The Spinifex Drifter ($49.99) is a great budget pick for moderate conditions, while premium options are available for more experienced campers.

Kathmandu
Renowned for quality and durability, Kathmandu is a favourite among seasoned outdoor enthusiasts. The Seeker 5 Sleeping Bag ($349.98) is a premium mummy bag with an adjustable hood and stash pockets—perfect for colder trips.

Big W
You don’t have to shop at a specialty store to get a decent sleeping bag. Big W’s Caribee Double Sleeping Bag – Firestone ($139) is a steal, especially for couples or casual campers. It’s rated to 0 °C and even includes built-in pillows.

Sea to Summit
Aussie-made and globally respected, Sea to Summit sleeping bags are designed for those heading into extreme environments. The Alpine II (−20 °C, $1,099) and Alpine III (−40 °C, $1,449) are built for true winter expeditions and pack down remarkably small for their insulation power.

Premium vs Budget Sleeping Bags
It’s true that premium sleeping bags can be a hefty investment—but for good reason. High-end bags offer better insulation, lighter weight, improved packability, and more durable materials. If you’re venturing into harsh climates or hiking deep into the bush, a quality bag is essential. On the other hand, if you’re planning a few family trips a year in fair weather, a budget option might do just fine.
Frequently Asked Questions (FAQ)

Down is lighter and warmer for its weight but performs poorly when wet. Synthetic is heavier but keeps you warm in damp conditions.
Which temperature rating do I need for Australian camping?
Summer campers should aim for comfort ratings of 5–10 °C, while winter adventurers should go for 0 °C or lower.
