Overall Results
The right sleeping bag for you ultimately depends on your specific needs, budget and the adventures you have planned. If you're tackling cold, alpine conditions or unpredictable weather, you'll need a high-performance, temperature-rated bag like a down-filled mummy bag. If you're buying for casual car camping, family trips, or summer festivals here in Australia, however, a simpler, more affordable rectangular synthetic bag will likely be a perfect and comfortable fit.

Sleeping Bag FAQs
Do temperature ratings on sleeping bags always reflect real-life warmth? - The ‘comfort’ or ‘temperature’ rating is based on lab tests using a sleeping pad, base layers and controlled conditions, but that doesn’t guarantee you’ll feel warm, as factors like sleeping pad quality, base layers, body type and how cold the ground is all affect actual warmth.
Can I camp in cold weather using a lightweight sleeping bag? - You could, but you’ll probably be cold overnight. A bag rated too warm for the conditions you’re sleeping in might get you through the night, but won’t keep you comfortable. You’d need extra layers, a warm sleeping pad, or even a liner to avoid a cold, restless sleep. Bushwalking Manual goes into sleeping bag temperature ratings for Australia, if you’re interested.
Do I also need a sleeping pad with a sleeping bag? - A good sleeping pad insulates you from cold ground and makes a big difference in how warm you stay. Sleeping directly on the ground, even inside a rated bag, often leads to heat loss and a cold night.
Is a down sleeping bag always better than a synthetic one? - Down bags usually offer better warmth-to-weight and pack down smaller, but they perform poorly if damp and take longer to dry. Synthetic bags are heavier and bulkier, but hold up better in wet conditions and are often more affordable. Sea to Summit explains more about what synthetic means in a sleeping bag.
What do ‘comfort,’ ‘limit’ and ‘extreme’ ratings mean on sleeping bags? - ‘Comfort’ is the lowest temperature at which an average person should be comfortable, ‘limit’ is for a warmer sleeper under those conditions and ‘extreme’ is a survival rating, meaning it might keep you alive, but you’ll be very cold and uncomfortable.
Do you always get what you pay for when buying a sleeping bag? - Not always, but cheaper sleeping bags often cut corners, such as with weaker zippers, thinner insulation and less durable fabric. They might be fine for a few seasons of light camping, but a quality bag holds up better under repeated use and varied conditions.
Should I choose a minimalist bag or a roomy one? - It depends on your camping style. A compact, tapered ‘mummy’ bag traps heat better, which helps in cold or backpacking trips. A roomier bag or rectangular style gives more comfort and space, which can be better for car camping or warm-condition trips.
Can I improve an existing sleeping bag’s warmth without buying a new one? - You can add a liner, use a thicker sleeping pad, wear warm base layers and keep your tent well-ventilated (to reduce moisture) to help make an existing bag warmer and more comfortable.
