When choosing a sleeping bag, it's important to consider its weight and packed size, especially if you're planning a human-powered overnight trip. Weight and packed size generally correspond, so you don't need to spend too much time considering them separately. However, it's worth noting that warmer bags are generally bulkier and heavier than colder bags. Therefore, when comparing weights, it's best to compare bags with the same temperature rating. The weight of a sleeping bag is largely determined by its insulation and shape. Down insulation is often more expensive, lighter, and more compressible than synthetic insulation, but synthetic insulation performs better in wet conditions.

What You'll Learn
Weight and warmth
The weight of a sleeping bag is an important factor to consider when choosing one, especially for backpacking. A sleeping bag can weigh as little as a pound and still keep you warm through the night. However, an extra pound or two can become significant on extended trips. The weight of a sleeping bag is determined mainly by its insulation and shape.
Down insulation is generally lighter, more compressible, and more durable than synthetic insulation. It also provides a more consistent level of warmth over time. Down fill is more expensive, but it tends to be extremely insulating for its weight. Synthetic fills retain insulating power when wet, are easier to clean, and are less expensive. Some sleeping bags use a blend of down and synthetic insulation, with synthetic insulation on the bottom and down on top.
The shape of a sleeping bag also affects its weight. Mummy bags, which taper heavily from the shoulders to the footbox, help keep weight to a minimum. Rectangular bags offer more room but will add considerable weight.
When choosing a sleeping bag, it's important to consider the temperature rating, which indicates the lowest temperature at which the bag is designed to keep a person warm. Warmer bags generally have more insulation and are bulkier and heavier. It's recommended to choose a bag with a temperature rating slightly lower than the typical low temperatures you anticipate encountering. Additionally, when comparing weights, it's best to compare bags with the same temperature rating.

Insulation type
The type of insulation is the primary factor in the size of a sleeping bag when it is in its stuff sack. The two types of insulation used in sleeping bags are down and synthetic. Down insulation is made from the soft, fluffy feathers found under the outer feathers of ducks and geese. It is lightweight, easy to compact into a stuff sack, and provides excellent warmth-to-weight ratios. However, down sleeping bags are more expensive and lose their insulating properties when wet. Synthetic sleeping bags are made from polyester fibres. They are bulkier and heavier than down but retain their insulating properties when wet and are typically more affordable. Synthetic sleeping bags are better for damp conditions or for repeated heavy use. Their insulation is much easier to wash and care for than down.
Down insulation is more expensive than synthetic insulation on average. Down is sought after because it is lighter and more compressible. Down fill is also more durable than synthetic fill, which means it retains a more consistent level of warmth for longer (decades, if properly cared for). "Fill power" is a specification that indicates the quality of down—a higher number indicates down that lofts higher to generate greater warmth for its weight. The priciest down bags, intended for extreme cold or ultralight backpacking, have the highest fill powers—closer to 800- than to 500-fill-power.
If you're car camping, you don't have to worry about weight or having to fit your bag in a pack, so you can go for the warmest, roomiest bag in your price range without worrying about bulk or weight. However, if you're backpacking, you'll want to minimize weight and bulk. Synthetic insulation performs better than down when damp. If you’re expecting wet weather, synthetic insulation could be the advantage you need.

Temperature rating
The temperature rating of a sleeping bag is a crucial factor in determining its suitability for your needs. Sleeping bags are designed to provide warmth and comfort during outdoor activities such as camping, backpacking, and hiking. The temperature rating indicates the lowest temperature at which the bag will keep you warm. It is important to choose a bag with an appropriate temperature rating to ensure a good night's sleep.
When selecting a sleeping bag, it is generally recommended to choose one with a temperature rating slightly lower than the typical low temperatures you anticipate encountering. This ensures that you will stay warm even in unexpectedly colder conditions. For example, if you are camping in an area where temperatures typically range from 30°F to 40°F, choosing a sleeping bag with a temperature rating of 20°F to 30°F would be advisable.
Different companies use different standards for their temperature ratings, so it is important to be mindful of these variations. The European Norm (EN) and the newer ISO system are widely followed and provide two ratings: "Comfort" (for women) and "Lower Limit" (for men). The "Comfort" rating indicates the temperature at which a standard woman in a relaxed posture would not feel cold, while the "Lower Limit" rating represents the temperature at which a standard man in a curled-up posture would not feel cold. However, it's important to note that temperature ratings are meant to represent survivable temperatures rather than comfortable ones. Therefore, when aiming for comfort, it is recommended to add around 20°F to the bag's rating.
The type of insulation also plays a significant role in the temperature rating of a sleeping bag. Down insulation, made from duck or goose feathers, is known for its excellent warmth-to-weight ratio and compressibility. It is lightweight, highly insulating, and durable. However, down insulation tends to be more expensive and may lose its insulating properties when wet. On the other hand, synthetic insulation is generally more affordable, performs better in wet conditions, and is easier to clean. Synthetic insulation may be bulkier and heavier than down, but it retains its insulating power even when wet, making it a good choice for humid environments. Some bags even feature a blend of down and synthetic insulation, combining the advantages of both materials.
When comparing sleeping bags, it is important to compare those with similar temperature ratings. This ensures that you are making an informed decision based on the bag's performance relative to its intended temperature range. Additionally, consider the features that enhance your comfort and convenience, such as adjustment options, stash pockets, and pad compatibility. Ultimately, the right sleeping bag for you will depend on factors such as the season, your typical camping temperatures, and your personal preferences for comfort and weight distribution.

Packed size
The packed size of a sleeping bag is an important consideration when choosing a sleeping bag, especially for backpacking. A sleeping bag takes up a significant amount of space in your pack, along with your sleeping pad and backpacking tent, so it's one of your largest pieces of gear.
The packed size of a sleeping bag is closely related to its weight, so you don't need to spend too much time considering them separately. In general, warmer bags are bulkier and heavier than colder bags, so when comparing packed sizes, be sure to compare bags with similar warmth.
The type of insulation is the primary factor in the size of a sleeping bag when it is in its stuff sack. Down insulation is more compressible than synthetic insulation, so it will pack down smaller. However, warmer bags with more down will generally have larger stuffed sizes. Synthetic insulation may be a better option if you're expecting wet conditions, as down insulation loses its performance when wet unless properly protected.
If you're looking for a lightweight, compressible bag, premium down fill is the best option. The Feathered Friends Egret YF 20 Women's Sleeping Bag is one of the lightest and most compressible bags on the market. The Mountain Hardwear Bishop Pass 15 is another good option, as it offers a solid balance of performance characteristics and packs smaller than other models that provide similar warmth.

Shape
The shape of a sleeping bag is a key factor in determining its weight and packed size, which are important considerations for any human-powered overnight trip. Mummy bags, for example, are some of the least spacious designs, tapering heavily from the shoulders to the footbox, which helps keep weight to a minimum. Rectangular bags, on the other hand, offer more room but will add a considerable amount of heft, making them more popular for car camping than backpacking. The shape of the sleeping bag also affects its warmth-to-weight ratio, with mummy bags being less spacious and therefore more efficient in retaining heat.
The weight and packed size of a sleeping bag are closely related, and it is important to analyse these factors between bags with similar warmth. Warmer bags are generally bulkier and heavier than colder bags, as they require more insulation and shell fabric to achieve a lower temperature rating. Therefore, it is worth spending a little more on a lighter or more compressible sleeping bag if you plan to venture deep into the backcountry, as every ounce counts when carried in a pack.
The shape of the sleeping bag also affects its durability and ability to maintain warmth in wet conditions. More complex construction methods can ensure even warmth throughout the bag, while additional features such as a well-designed hood or draft collar can provide extra warmth and prevent heat loss. A good sleeping bag should keep you warm all night, and it is recommended to choose a bag with a temperature rating slightly lower than the typical low temperatures anticipated on your trips.
The type of insulation also plays a role in the shape of the sleeping bag. Down insulation, for instance, is lighter and more compressible than synthetic insulation, allowing for a more streamlined shape that minimises heat loss. Synthetic insulation, on the other hand, may be bulkier and heavier, requiring more space to accommodate a comparably warm bag. Additionally, the "fill power" of down insulation indicates its quality, with higher numbers lofting higher to generate greater warmth for its weight.
