When it comes to choosing the best infill for a sleeping bag, there are a few options to consider. The most common types of infill are down and synthetic. Down, which is made from the feathers of birds, is known for its insulating properties and great warmth-to-weight ratio. It is also long-lasting and compressible but tends to be more expensive and requires careful maintenance. Synthetic infill, on the other hand, is made from materials like polyester and is generally more affordable, easier to clean, and retains insulation when wet. However, it is slightly bulkier and may not last as long as down. Other factors to consider when choosing a sleeping bag include the temperature rating, the R-value of the sleeping pad, and the design of the bag, such as mummy bags or backpacking bags, to ensure comfort and functionality for your specific needs.
| Characteristics | Values |
|---|---|
| Temperature rating | Choose a sleeping bag rated a little below the typical low temperatures you expect. |
| Sleep system | Comfort at a particular temperature depends on variables like the R-value of the sleeping pad and the sleeper's clothing. |
| Type of insulation | Down vs synthetic. Down is more expensive, lighter, compressible, durable, and suitable for dry, cold environments. Synthetic insulates when wet, is cheaper, easier to clean, and non-allergenic. |
| Weight | The quality of insulation and the cut of the bag determine weight. |
| Features | Adjustment features, stash pockets, and pad compatibility are important. |
| Shell material | Nylon, polyester, or taffeta are good for saving money and indoor use. Ripstop is reinforced and suitable for dry hiking. Dryloft is the most expensive. Microfiber is lightweight and windproof. |

Down vs synthetic fill
When choosing a sleeping bag, there are several factors to consider, including the type of insulation. Sleeping bags are usually insulated with either down or synthetic fills. Both have their pros and cons, and the right choice depends on factors such as the weather conditions, weight requirements, and budget.
Down insulation is made from the soft, fluffy plumage found underneath the exterior feathers of waterfowl, such as ducks and geese. It is incredibly insulating and has an excellent warmth-to-weight ratio, making it ideal for cold, dry environments. Down sleeping bags are typically lighter, more compressible, and more durable than their synthetic counterparts. They also require less down to fill space and achieve a certain temperature rating, resulting in a lighter product. However, down insulation tends to be more expensive, and one of its main drawbacks is its performance when wet. Down has a tendency to clump up and lose its loft and insulating properties when exposed to moisture, which can be an issue in damp climates or rainy weather.
Synthetic insulation, on the other hand, is usually made from polyester. It is quick-drying and continues to insulate even when wet, making it a better choice for humid or rainy conditions. Synthetic fill is generally less expensive, durable, and hypoallergenic. It comes in two types: short-staple and continuous filament. Short-staple insulation features densely packed fine-denier filaments, resulting in a soft, flexible, and compressible sleeping bag. Continuous-filament insulation uses thicker filaments that provide loftiness, strength, and durability. However, synthetic insulation may be heavier and less compressible than down, and it can be challenging to compare products due to the variety of branded names available.
Some manufacturers offer hybrid sleeping bags that combine water-resistant down and synthetic insulation to provide the benefits of both materials. These bags may blend the insulations throughout or use different types of insulation in specific locations, such as durable synthetic on the bottom and lofty down on top.
When deciding between down and synthetic insulation, it is essential to consider the weather conditions, the weight and compressibility of the bag, your budget, and your personal preferences. Both options have unique advantages and can provide a comfortable and warm sleeping experience when used in the right environments.

Goose down
While goose down is an excellent choice for dry, cold environments, it is important to note that it does not perform as well as synthetic fills when wet. Synthetic insulation is a better option if you anticipate camping in rainy or snowy conditions. However, some goose down bags are now treated with water-repellent coatings, increasing their suitability for damp environments.
When choosing a goose down sleeping bag, consider the fill power, which indicates the amount of space one ounce of down will occupy, and is a measure of insulation and compressibility. A higher fill power means better insulation and compressibility, so look for bags with a higher rating if these features are important to you.
Finally, remember that a sleeping bag is just one part of your sleep system. The sleeping pad and your clothing also play crucial roles in keeping you warm. Choose a sleeping bag rated slightly lower than the typical low temperatures you expect, and pair it with a high-quality sleeping pad to ensure a comfortable and warm night's sleep outdoors.

Temperature ratings
The warmth of a sleeping bag is often advertised as its temperature rating. This is a metric that is supposed to indicate the lowest temperature at which the bag should keep you warm. However, in reality, it is not that simple. Many companies choose their own temperature ratings, making it difficult to compare between companies. Most backpacking bags are rated according to an industry-standard EN test, which provides a more consistent measure of warmth.
The temperature rating of a sleeping bag is based on an "average sleeper", and it is important to note that there are many other factors that will affect how warm you feel. These include the R-value of your sleeping pad, what you wear to sleep, humidity, wind, your metabolism, and more. It is recommended that you select a sleeping bag with a temperature rating that is lower than the lowest temperature you expect to encounter, as you can always open up a bag to cool down.
Lab-tested temperature ratings, as indicated by "EN" or "ISO" ratings, are useful for making direct comparisons between sleeping bags from different brands. The EN standard was the original standard adopted by the sleeping bag industry, and today, the ISO (International Standards Organization) oversees bag testing, with a nearly identical testing method. This means that you can compare an old EN-rated bag to a newer bag with an ISO temperature rating. An "ISO" or "EN" temperature rating indicates that you can reliably compare any two backpacking sleeping bags.
The warmth of a sleeping bag is also influenced by its shape. Sleeping bags come in three basic shapes: rectangular, semi-rectangular or "modified mummy", and mummy. Rectangular bags allow plenty of room for the legs and arms to stretch out and can sometimes be completely unzipped and used like a comforter. Semi-rectangular bags offer a compromise between warmth and roominess, while mummy bags have a slim cut and a snug fit to boost warmth and reduce weight. Mummy bags are also contoured so that you roll over with your bag rather than inside it. Mummy bags are often insulated with a hood for extra warmth.
In addition to the shape of the sleeping bag, the insulation fill weight can also affect the warmth of the bag. The insulation fill weight tells you the weight of the insulation in the bag, and more fill generally means a warmer bag. However, the temperature rating is a more reliable indicator of warmth.

Fill power
Down insulation in sleeping bags typically ranges from 400 to 900. A fill power of 500-550 is considered good, 600-700 is considered very good, and 800-900 is considered outstanding. A higher fill power indicates that the down is more resilient to compression, lofts better, and can trap more air. This means that sleeping bags with a higher fill power will provide the same level of warmth with less insulation by weight.
It is important to note that the temperature rating of a sleeping bag is not solely determined by its fill power. A sleeping bag with a lower fill power can have a higher temperature rating if it contains more down. Additionally, the sleeping pad used in conjunction with the sleeping bag will also affect its warmth. A high-quality sleeping pad with a high R-value will provide better insulation from the cold ground.
When choosing a sleeping bag, it is worth considering the Responsible Down Standard (RDS) certification, which ensures that the down and feathers used have not been subjected to unnecessary harm. Additionally, the type of down used, such as duck or goose down, will also affect the performance of the sleeping bag.

Sleep systems
When it comes to sleep systems, the most important thing is finding a combination of components that will keep you comfortable and help regulate your temperature at night. This includes the sleeping bag, sleeping pad, and clothing.
The sleeping bag fill insulates you from the cold by trapping body heat and preventing the exchange of warm and cold air. There are two main types of sleeping bag insulation: down (natural) and synthetic fill. Down is incredibly insulating and has a great warmth-to-weight ratio, making it the warmest insulating material available ounce for ounce. It is also lightweight, compressible, and durable, retaining its performance for decades if properly cared for. However, down is expensive and high-maintenance. When down gets wet, it loses most of its insulation value and takes a long time to dry. Some manufacturers apply a durable water-repellent (DWR) treatment to their down sleeping bags to help with this issue.
Synthetic insulation, on the other hand, is a lab-created alternative to down. It continues to insulate when wet, making it the better option for damp climates. Synthetic bags are also easier to clean, less expensive, and non-allergenic. However, they are slightly bulkier and heavier, and may not last as long as down bags. There is also a huge variation in quality within the synthetic sleeping bag market, so it's important to remember that you generally get what you pay for.
The Responsible Down Standard (RDS) ensures that down and feathers come from animals that have not been subjected to unnecessary harm. If you choose a down sleeping bag, look for RDS certification from the manufacturer.
In addition to the type of insulation, there are other factors to consider when choosing a sleeping bag. The temperature rating is important, but it is not a guarantee of warmth. Choose a bag rated slightly lower than the typical low temperatures you anticipate. The fill power also matters, but it is different from the temperature rating. A sleeping bag with a lower fill power can have a higher temperature rating if there is more down inside the bag (making it heavier). Loft, or the 'fluffiness' of the down, is another factor that affects the bag's insulating power. The higher the loft, the more efficiently the bag will trap air and insulate you.
The shell or exterior material of the sleeping bag is also important, especially in terms of water resistance and durability. For wet climates, Dryloft or Gore-Tex are the best shell materials, especially with down filler. These materials are water-resistant but not very breathable, so they may trap moisture inside the bag. For moderate weather, a soft and smooth fabric like polyester or nylon is a good choice. These synthetic fabrics are affordable, breathable, and comfortable, but not as durable as other options. Ripstop, made from reinforced nylon or polyester, is a durable and breathable option for dry climates, but it is not ideal for wet conditions.
The sleeping pad is another crucial component of your sleep system. A sleeping bag alone won't provide enough insulation from the cold ground, so you'll need a high-quality pad with a high R-value, which measures the pad's ability to insulate you from the ground.
Finally, don't forget that your clothing is also part of your sleep system. The tested temperature ratings of sleeping bags are based on a person wearing long underwear and socks, so dress accordingly.
