Sleeping rough in style
It was after a weekend getaway that the question hit me – somewhere between wrestling with a lumpy bundle of nylon and trying (unsuccessfully) to get it back into the stuff sack it came in. As I sat there, arms flailing and language becoming increasingly unprintable, I found myself wondering… who invented the sleeping bag? Where did the idea come from? And how on earth did we end up with something that offers so much comfort, yet fits into a bag the size of a rugby ball (apparently only when packed by professionals or factory robots)?
Turns out, the sleeping bag has a fascinating backstory – one that involves Arctic explorers, European aristocrats, and a few rather questionable early designs. Let’s unzip the history of this outdoor essential.
Wrapped up like a mummy
While the modern sleeping bag is a relatively recent invention, the idea of wrapping oneself in protective layers to sleep outdoors is as old as humankind. Our prehistoric ancestors probably slept under animal skins or furs, bundled up in makeshift bedding to keep out the cold.
Fast-forward to the early centuries AD, and nomadic tribes across Central Asia were known to use padded and insulated bedding made from wool, leather and felt – all designed to offer a warm night’s rest in unforgiving climates.
But it wasn’t until the age of exploration that the need for purpose-made sleeping gear really started to emerge.
Early expedition gear
In the 18th and 19th centuries, as explorers and military expeditions pushed into colder, more remote regions, the sleeping bag began to take shape – albeit in a rudimentary form. Arctic and Antarctic explorers, like the legendary Ernest Shackleton, often slept in fur-lined reindeer skin bags, which were bulky, heavy and far from waterproof. But they were warm, and that was enough when temperatures dipped below freezing.
Some early mountaineers favoured canvas bedrolls – essentially a blanket sandwich with waterproof outer layers. These were heavy-duty affairs, often lined with wool or flannel, and designed to be rolled up and strapped to a packhorse. They kept the wind and moisture out (mostly) and became a staple of military and frontier life in the 1800s.
The first modern sleeping bag
The first commercial sleeping bag as we’d recognise it today appeared in the late 1800s, and it came from an unlikely source – a Norwegian outdoorsman named Fridtjof Nansen. While preparing for his 1891 crossing of Greenland, Nansen designed a primitive sleeping bag using layers of reindeer fur stitched together into a cocoon shape. It was bulky, but it worked – and it sparked wider interest in the idea of a lightweight, portable sleeping solution.
In 1876 (a few years earlier, interestingly), a Welsh-born inventor named Pryce-Jones began mass-producing what he called the “Euklisia Rug” – essentially a wool blanket with a sewn-in waterproof cover and a pocket for a pillow. He marketed it to the British military and sold over 60 000 of them, including to the Russian army. It’s often considered the first commercially produced sleeping bag, even though it was more of a glorified bedroll.
Military innovation and the rise of down
World War I and II brought huge advances in outdoor gear, as armies needed better equipment for troops in cold or mountainous regions. It was during this time that down insulation – previously used mostly in bedding – found its way into field gear. Feather-filled bags offered an excellent warmth-to-weight ratio and could be packed relatively small. The downside? Once wet, down becomes about as useful as a soggy newspaper.
After the war, surplus military gear found its way into the hands of civilian adventurers, mountaineers and early overlanders, fuelling the rise of recreational camping. Sleeping bags were now widely available – and steadily improving.
Enter synthetic insulation and the zip
By the 1950s and 60s, the sleeping bag was undergoing a full makeover. Synthetic insulation materials like polyester fill and hollow-fibre made bags more affordable, lighter, and better in wet conditions. Manufacturers also started adding features like zips, hoods, draft collars and stuff sacks – turning the sleeping bag into the modern marvel we know today.
The shape also evolved. Early sleeping bags were rectangular and roomy, but not very efficient at retaining body heat. The “mummy” design – tapered at the feet and snug around the shoulders – became popular with hikers and climbers who needed to save space and stay warm. This design, inspired by ancient Egyptian burial wraps (hence the name), is still the standard for cold-weather bags.
From basic to bonkers
These days, sleeping bags come in just about every flavour you can imagine – from ultralight options for gram-counters to luxury bags with built-in heaters, Bluetooth speakers and even armholes so you can cook breakfast without getting out of bed.
There are down bags, synthetic bags, bags shaped like elephants (really), and zip-together couples’ bags. You can get four-season expedition bags rated for -40°C, or summer bags that compress down to the size of a water bottle. There are even sleeping bag suits that let you shuffle around camp like a human marshmallow.
And of course, technology hasn’t stopped. New materials like PrimaLoft, recycled synthetic fills, and advanced water-resistant down are making sleeping bags lighter, warmer and more durable than ever.
Whether you’re sleeping in the back of your bakkie, pitching a tent in the Tankwa Karoo, or hammocking in the Cederberg, a good sleeping bag is worth its weight in gold. It’s the difference between a miserable night and a restful one – between waking up stiff and frozen or ready for the next leg of your adventure.
So next time you zip yourself in and nestle down for a night under the stars, give a little nod to Fridtjof Nansen, Pryce-Jones, and the countless trailblazers who paved the way. Because while a sleeping bag might seem like a simple thing, it’s actually the result of centuries of innovation, adaptation and good old-fashioned trial and error.
Choosing the right bag and showing it some love
Of course, knowing the history of the sleeping bag is one thing. Choosing the right one for your adventures is another.
When it comes to selecting a sleeping bag, the first thing to consider is the season and conditions you’ll be using it in. A bulky four-season bag with a -10°C comfort rating is overkill for a summer weekend in the bushveld – unless you enjoy waking up drenched in sweat and questioning your life choices. Similarly, a featherweight summer bag isn’t going to do you much good in the Drakensberg mid-winter.
Look for the EN13537 comfort rating on the label – it’ll give you a ballpark idea of the temperatures the bag is designed for. Down-filled bags offer excellent warmth-to-weight performance but lose insulation value when wet, while synthetic bags are a bit bulkier but generally more forgiving in damp conditions.
Shape matters too. Mummy-style bags are warmer and lighter, ideal for hiking and cold weather. Rectangular bags are more spacious and comfortable, perfect for casual camping and road trips. Some even zip together to form a double… for those who enjoy spooning in the wilderness.
And once you’ve found your perfect match, don’t neglect it. A sleeping bag that’s well cared for can last years, if not decades.
When you get home, don’t just cram it straight back into its stuff sack and forget about it. Air it out thoroughly to avoid mould and smells and store it loosely in a larger breathable bag – not tightly packed. Most bags are machine washable (check the label) but always use a front-loader and a gentle detergent. Better yet, invest in a liner to keep it clean inside; it’s much easier to wash than the whole bag.
With a little care, your sleeping bag will be ready and waiting for many more nights under the stars, whether it’s rolled out in the Kalahari, tucked into the rooftop tent, or stubbornly refusing to go back into its bag at home.
