A restful night in the outdoors requires two things: warmth and space. Many sleeping bags nail the warmth part but leave you feeling like a compressed sausage. That’s why the Kings sleeping bags are such a game-changer for car campers. Built by Kings to be one of the biggest bags on the market, it boasts massive dimensions and a -2°C temperature rating, making it a comfortable option across most of Australia’s seasons.
The good
- Rated for -2°C comfort
- Massive size 2.4 m long, 90 cm wide
- Combine two bags for 1.8 m width
- Heavy-duty 500GSM hollow cotton fill
- Durable 210D Oxford compression bag
The not-so-good
- Heavy weight at 2 kg
- Bulky packed size 40 cm x 26 cm
- 70D outer material is not premium soft
Better yet, if you camp with a partner, these bags zip together to create a giant sleeping solution. I took the bag out for a few cold nights to see if this colossal size sacrifices core performance.
What You’re Getting
A durable, hooded sleeping bag rated to -2°C with a 500GSM fill. It measures 240 cm x 90 cm and can be zipped together with a second bag to form a double.

First impressions
The moment I pulled the kings sleeping bags out of the box, the first thing I noticed was the scale. Measuring 240 cm long and 90 cm wide, this bag is truly huge. Perfect for anyone who feels cramped in a standard mummy bag. The second thing that impressed me was the solid 210D Oxford-Cotton Compression Bag that comes included. This isn’t one of those cheap, flimsy sacks; it feels tough and reliable, and its straps make cinching the bag down a manageable task.
The bag itself weighs a solid 2 kg, which is on the heavier and bulkier side. I specifically tested zipping a left and right-hand zip version together, and the quality SBS zippers mated easily and cleanly, creating an impressive 180 cm wide sleeping solution that would easily fill a double swag or large rooftop Tent.
Materials & Build Quality
Kings has designed this bag for durability, not ultralight hiking. The shell is made from 70 denier Polyester, which is tough and lightweight enough to handle rough camp life without tearing easily. The interior warmth comes from a 500GSM (grams per square meter) hollow cotton insulation filling, constructed of two 250GSM layers. This double-layer design is great for warmth and comfort, preventing cold spots. The 500GSM is a substantial amount of fill, justifying the -2°C rating.
All the hardware feels reliable, especially the Quality SBS Zippers, which are smooth and feature a velcro strap to prevent accidental opening during the night. The inclusion of the sturdy 210D Oxford-Cotton Compression Bag underlines the focus on long-term use and transport protection, which is vital when tossing gear into your 4WD Storage.
Ergonomics & Weight
The ergonomics of the Kings sleeping bags are all about maximizing comfort for the average camper. The impressive 2.4 m overall length (which still leaves a massive 2.1 m of body space without the hood) means even the tallest user won’t feel their feet pushing against the end. The generous 90 cm width offers plenty of room to roll over or sprawl out, it truly feels like sleeping in a doona.
The main trade-off for this size and warmth is the weight and packed dimensions. At 2 kg, this bag is far too heavy and bulky for backpacking. The packed size of 40 cm x 26 cm x 26 cm takes up significant space. However, for those that are on the road to reach their destination, the weight is irrelevant. The bag’s high comfort and thermal performance more than justify the heft when your focus is on a great night’s sleep in your rooftop tent or swag.
Performance & Features
The key performance metric is the -2°C rating, which I found to be accurate for a cozy night’s sleep. The double-layered 500GSM insulation works hard to trap heat. An essential feature for maintaining this warmth is the hooded design with an adjustable drawstring. Being able to cinch the hood keeps radiant heat from escaping around your neck and head, eliminating common cold spots.
The most unique and versatile feature is the ability to zip two bags together. The option to choose left or right-hand zips allows you to buy a matching pair and combine them into a massive 180 cm wide double sleeping system. This is perfect for couples and is a feature rarely found in bags of this price point and rating. Packing the bag is easy thanks to the included compression bag, which helps pull the sizable insulation down to its compact 40 cm packed length.
Gear That Complements Your Camping Setup
Since the Kings sleeping bags are built for car camping and 4WD touring, they pair perfectly with other durable Sleeping Gear. You might want to consider a high-quality self-inflating Sleeping Pad to ensure insulation from the ground.
For couples who zip two bags together, a large double Swag or a spacious Rooftop Tent is a must-have. Don’t forget to check out our guides on Camp Lighting to help you pack up after a great night’s sleep.
The Adventure Kings sleeping bags deliver exactly what they promise: massive size, reliable warmth, and great durability for a demanding outdoor environment.
While its substantial 2 kg weight and large packed size make it strictly a car camping option, the comfort provided by the 2.4 m length and the protective -2°C rating are excellent. The ability to zip two together to form a gigantic double bag is the standout feature for couples. If your priority is maximum space and reliable warmth without having to worry about delicate ultralight fabrics, this bag is a superb investment in your camping comfort.
This sleeping bag is best for car campers, families, and couples using large Swags or Rooftop Tents. It is ideal for anyone who needs reliable cold-weather protection (down to -2°C) and prioritizes interior space over minimal pack size.
Absolutely. The Kings sleeping bags offer exceptional value for their size, durability, and temperature rating. The tough 70D Polyester shell and high-quality 500GSM fill ensure this bag will last for years, making it a smart and cozy purchase.
