What You'll Learn
Synthetic bags are better at insulating when wet
Synthetic sleeping bags are a popular choice for camping and outdoor activities. While they may not be as lightweight or compressible as down sleeping bags, they offer a significant advantage in terms of insulation when wet. This feature makes them a preferred option for many campers and outdoor enthusiasts.
Down sleeping bags are known for their superior warmth-to-weight ratio and are often favoured by backpackers due to their lightweight and compressible nature. However, down has a significant drawback: its inability to insulate when wet. When down feathers get wet, they lose their loft, which is crucial for trapping air and providing insulation.
On the other hand, synthetic sleeping bags are made from materials like polyester insulation, which can retain their insulating properties even when damp. This means that if your synthetic sleeping bag gets slightly wet, it will still provide you with more warmth than a wet down bag. Unless, of course, the down bag is made of hydrophobic down or has been treated with a water repellent, which can improve its moisture resistance.
The ability of synthetic bags to insulate when wet is a significant advantage, especially in humid or wet outdoor conditions. Synthetic bags also dry much quicker than down bags, allowing you to pack up and move on to your next destination sooner. This faster drying time is beneficial not only during your trip but also when it's time to clean and store your sleeping bag.
It's worth noting that synthetic sleeping bags are generally less expensive than down bags, making them a more budget-friendly option. Additionally, synthetic bags are often considered lower-maintenance, although proper care and maintenance are necessary to maintain their insulation performance over time.

Synthetic bags are heavier than down bags
Synthetic sleeping bags are heavier than down bags. This makes down bags a preferred choice for backpackers and trekkers who need to conserve every ounce of weight in their packs. The weight difference is a few hundred grams, which may not seem like much, but for adventurers pushing their performance across challenging activities like hiking, biking, and pack-rafting trips, it can be a big deal—even a deal-breaker.
Down bags are made from the soft, wispy plumage found underneath the exterior feathers of waterfowl, such as geese and ducks. These fluffy filaments, called plumules, have a unique structure that allows them to expand and trap air, making them an incredibly lightweight yet powerful insulator. This is why down bags have a higher warmth-to-weight ratio than synthetic bags. It takes much less down to fill the same area because it lofts more and insulates better.
Synthetic bags, on the other hand, are made from plastic. While they can provide the same warmth as down bags, they require more material, making them heavier. Synthetic bags also don't compress as well as down bags, which is another important consideration when space is limited. However, synthetic bags have the advantage of still being able to insulate when wet, whereas down loses its insulating properties once it gets wet.
For those looking for the best of both worlds, hybrid sleeping bags blend down and synthetic insulations. These bags use synthetic insulation in areas more likely to get wet, like the footbox, and down insulation in areas that need the most insulation, like the top side and chest area. This combination provides consistent warmth across the body, regardless of the weather.

Synthetic bags are cheaper than down bags
Synthetic sleeping bags are generally much cheaper than down bags. Synthetic bags are made from plastic, and their "fluff" is easily produced in a factory. Synthetic fills are also more durable than down, which means they can last longer.
Down sleeping bags, on the other hand, are usually more expensive. They are made from the undercoat of bird feathers, most commonly duck and goose. The quality of down varies depending on the bird, with goose down being more expensive than duck down. However, duck down provides great value for money as it has a similar performance to goose down at a lower fill power.
While down bags are lighter and warmer than synthetic bags, they are more difficult to dry and lose their insulating power when wet. Synthetic bags, on the other hand, maintain their insulating power in damper conditions and dry much faster. This makes them a more reliable option, especially in humid climates.
In terms of compressibility, down bags are easier to compress into a stuff sack, making them more convenient for backpackers. Synthetic bags, however, may be preferred by car campers as they are cheaper and weight and packed size are less important factors.
Overall, synthetic sleeping bags offer a more affordable, durable, and reliable option compared to down bags, especially in humid climates or for those starting out with camping or backpacking.

Synthetic bags are less compressible than down bags
Synthetic sleeping bags are less compressible than down bags. Down bags are almost always lighter than synthetic bags with the same warmth rating, making them the preferred choice for backpackers and trekkers who need to conserve weight in their packs. Down bags can be compressed much smaller than synthetic bags, making them ideal for situations where pack space is important, such as multi-day hiking or backpacking trips. Down sleeping bags are also favoured for their unbeatable warmth-to-weight ratio. It takes much less down than synthetic material to fill the same area because it lofts more and insulates better due to its structure of fine, branched filaments.
However, synthetic bags have their advantages, too. Synthetic sleeping bags can provide just as much warmth as a down sleeping bag of the same temperature rating. Synthetic bags are also better at insulating when wet. While hydrophobic down treatments have improved at repelling moisture, no down is 100% waterproof. Wet synthetic bags will still provide more warmth than a wet down bag. Synthetic bags also dry much quicker than down bags, which can be helpful when packing up or trying to get into a warmer sleeping arrangement.
The type of sleeping bag that is best for you depends on how and where you'll be using it. For example, if you're going on multi-day hikes or backpacking trips, a down bag might be a better choice due to its compressibility and light weight. On the other hand, if you're looking for a bag that can provide warmth in wet conditions, a synthetic bag could be a better option.
There are also hybrid sleeping bags that blend the two insulations, offering the benefits of both materials. Some hybrid bags have full down insulation in some parts of the bag and full synthetic insulation in other parts, while others have a combination of down and synthetic materials throughout the bag. These hybrid bags perform better in mixed weather conditions and when wet or damp, as they give consistent warmth across the body regardless of the weather.

Synthetic bags are lower-maintenance than down bags
Synthetic sleeping bags are often considered lower maintenance compared to down bags. While both types of sleeping bags should ideally be stored uncompressed, synthetic bags are easier to maintain as they can be stored in a sleeping bag storage sack, whereas down bags should not be stored in their stuff sack. This is because crushing the loft of down will reduce its insulating properties over time.
Synthetic bags are also easier to clean. Down bags require a gentle hand-washing process in a bathtub with a specially formulated down wash, followed by drying in a tumble dryer with purpose-built balls that fluff up the down. Synthetic bags, on the other hand, can be machine washed and dried without the need for special equipment or detergents.
Additionally, synthetic bags are more durable and long-lasting. Down bags, if not cared for properly, can lose their loft quickly and are difficult to dry. Synthetic bags, on the other hand, dry much quicker than down bags, which is especially useful if your bag gets wet during your trip.
Synthetic bags are also more affordable than down bags, making them a more accessible option for many people. They provide just as much warmth as down bags of the same temperature rating, but at a more affordable price point.
Overall, while both types of sleeping bags require proper care and maintenance, synthetic bags are generally considered lower maintenance due to their ease of storage, cleaning, durability, affordability, and warmth retention.
