How To Choose A Sleeping Bag
Before jumping into our picks, a quick rundown on the four things that actually matter when choosing a sleeping bag.
Temperature rating
Every sleeping bag is rated to a temperature — the lower the number, the warmer the bag. As a rough guide, match the rating to the coldest conditions you realistically expect to camp in, then add a few degrees of buffer. A -5°C bag is plenty for most three-season Australian camping; sub-zero alpine trips and outback winters call for -10°C or colder. Manufacturers typically quote a “comfort” rating (the temperature you’ll sleep comfortably at) and a “limit” rating (the lowest you’ll survive in) — always plan around the comfort rating.
It’s a good idea to think about your sleeping bag rating as part of your complete sleep system, have a listen to our discussion with Sea To Summit here on the topic.
Down vs Synthetic
Down offers the best warmth-to-weight ratio, packs down smaller, and lasts two to three times longer than synthetic — making it the go-to for hiking, ultralight adventures, and anyone investing in a bag for the long haul. The catch: down loses up to 90% of its warmth when wet and takes a long time to dry, so it’s a poor fit for damp climates or water-based trips. Quality is measured in fill power (the cubic inches one ounce of down lofts to) — entry-level sits around 400, premium climbs to 850–900.
Synthetic fill is cheaper upfront, retains around 50% of its warmth when wet, and dries faster — ideal for car camping, kids, school camps, occasional users, and humid or wet conditions. The trade-offs: it’s heavier, bulkier, and tends to lose loft within about five years of regular use.
Short version: down for hiking and long-term investment; synthetic for car camping, kids, and wet weather.
Shape and design
- Mummy / tapered bags hug the body and trap heat efficiently — warmest option, lightest pack size, best for hiking and cold conditions.
- Rectangular bags offer more room to move and feel less restrictive — better for car camping where weight isn’t critical.
- Double bags suit couples and provide the option to zip into two singles.
- A hood dramatically improves heat retention — heat escapes fastest through your head.
- Full-length zips add versatility (vent on warm nights, seal up on cold ones); foot zips let the bag open out as a quilt.
Shell fabric
Sleeping bags don’t need to be fully waterproof, but a water-resistant shell is worth having — it buys you time against tent condensation, accidental splashes, and damp ground. Most modern bags use lightweight ripstop nylon or polyester that strikes a sensible balance between weight, durability, and weather protection.

Best Rated All-Round Sleeping Bag
I’m going out on a limb here, as these bags are relatively new at the time of writing – but myself and the whole Snowys crew are all in agreement that the quality and features offered by the Sea to Summit Circuit Sleeping Bags make it the best value all-round sleeping bag for any camping and hiking adventure in our range.
When putting this bag together, Sea to Summit took the best elements from across their performance sleeping bag range – many of which feature throughout this article – and bundled them into the Circuit. The result is a smart balance of materials and construction that keeps the price at an entry-level point for down sleeping bags, without cutting corners where it counts.
You’re getting high-quality 650+ loft duck down, recycled fabrics, full-length double zippers, a well-balanced foot box, and a technical but roomy cut. It’s a bag you can genuinely take from the hiking trail to the rooftop tent – and one that earns its place as the do-it-all option in your kit.

Best Quilt For Camping
From campfire snuggles to chilly mornings inside the swag, the Coleman Outdoor Blanket Double is the versatile camp companion that keeps you and your mate cosy from dusk till dawn.
If you’re sleeping on a well-insulated mat, you don’t need the bottom layer of a sleeping bag working overtime – a quality blanket like this one does the job from the top down, cutting bulk without cutting warmth. That’s a win for rooftop tent owners, where less bedding means an easier close at pack-up, and just as handy for swag campers chasing a tighter, easier roll come morning. You even can grab it on the way out to the campfire for warmth around the flames, or drape it over the kids on the camp chairs to keep them warm wherever they are in the campsite.
Whether it’s rolled into your swag, tucked into the rooftop tent, or wrapped around shoulders by the fire, the Coleman Outdoor Blanket Double has roasty-toasty camping covered for two.
See our full range of quilts and blankets for camping here.
Best for: Use in rooftop tents or swags to reduce bulk when used on top of a well insulated mattress
Sleeping Bag FAQ’s
As a general rule, down offers the best warmth-to-weight ratio, making it the top pick for ultralight gear seekers. Down can also be rejuvenated and re-lofted, giving it a longer lifespan than synthetic fill. However, if down gets wet it can lose its insulation properties entirely, and takes longer to dry than synthetic – making it less suitable for damp climates and water-based adventures.
If you want to reduce bulk, a quilt or blanket is handy — provided you’re sleeping on a well-insulated mat. In that setup, the mat handles insulation from underneath while the quilt does the work on top, cutting down the overall bulk of your bedding. Very handy for making rooftop tent pack-up easier, or for swag campers chasing a tighter roll come morning.
Some sleeping bags can go in a washing machine, though you may need to head to the laundromat to find one big enough. Use a gentle wash, and only put synthetic bags in the machine. Down bags require a little more care — check out our guide on how to wash a down sleeping bag for full instructions.
Quickest answer: don’t. If you’re not fussed about crinkle lines when you unpack it, the easiest way to get it back in the stuff sack is to, well… stuff it in. Watch our video here on how to pack your sleeping bag.
A sleeping bag liner is a fabric sack — usually cotton, silk, or synthetic blends — that sits inside your sleeping bag to create a layer between you and the lining. Liners add a bit of warmth (some more than others), but the bigger benefit is hygiene: it’s far easier to regularly wash a liner than the bag itself, which keeps things fresh and extends the life of your sleeping bag.
