Mummy sleeping bags are a popular choice for backpackers and campers. They are designed to be lightweight and compact, making them easy to carry on long hikes or when packing space is limited. Mummy bags are tapered, snugly fitting around the body, which maximises heat retention. While this makes them efficient in cold conditions, it can also be restrictive for those who move around in their sleep. Some mummy bags feature innovative designs to address this issue, such as the spoon-shaped Nemo Disco, which offers more room for sleepers to shift positions. The Feathered Friends Hummingbird UL is another mummy bag that offers an unparalleled warmth-to-weight ratio, although it comes with a high price tag. For those on a budget, the Mountain Hardwear Bishop Pass 15 provides a solid balance of performance and affordability. Ultimately, the best mummy sleeping bag will depend on individual preferences, sleeping habits, and budget constraints.

What You'll Learn
Mummy bags vs quilts
Mummy bags and quilts are both popular options for sleeping outdoors, but they have distinct advantages and disadvantages. Here is a detailed comparison to help you decide which option is best for you:
Design and Comfort
Mummy bags are designed to be narrow at the feet, wider at the shoulders, and often include a hood around the head. They can feel restrictive and are not ideal if you want more space to move around. Quilts, on the other hand, provide only a top layer, similar to a blanket. They drape over the body and focus the insulation on the top, assuming that your sleeping pad will provide insulation at the bottom. Quilts offer more freedom of movement and are a good choice if you tend to feel restricted in enclosed spaces.
Warmth and Temperature Regulation
Mummy bags are known for providing excellent warmth due to their draft-free design that fully encloses the body, including the head. The insulation wraps around the bag, creating a physical barrier that retains heat and keeps out cold air. However, temperature regulation can be challenging in mummy bags. If it gets too warm, you may need to unzip the bag, which can be inconvenient and disrupt your comfort. Quilts, on the other hand, offer adaptable warmth. On mild nights, they can be used as cozy blankets, and on colder nights, they can be secured tightly around the body for enhanced insulation. Quilts are a good choice if you tend to sleep hot or prefer to adjust your temperature throughout the night.
Weight and Portability
Mummy bags, especially those designed for backpacking, prioritize low weight and packed size. Ultralight mummy bags achieve this by using thinner shell materials, higher-fill-power down, and shorter zippers. Some even eliminate the hood and zipper, resulting in a tube-style design. Quilts are also known for being lightweight and space-saving due to their smaller size and less material. They are a popular choice among thru-hikers and long-haulers who want to optimize their gear setup.
Versatility and Ease of Use
Mummy bags are simple to use and provide a cozy, enclosed space. They are an excellent choice for recreational backpackers who prioritize simplicity and warmth. Quilts offer versatility and are ideal for those who want to adjust their sleeping setup based on the weather conditions. However, quilts may require additional head coverage, and the quilt/sleeping pad system may not always provide a perfect seal, potentially letting in drafts.
Cost
Both mummy bags and quilts are available in a range of prices, depending on the brand, materials, and features. It is important to consider your budget and the specific features that are most important to you when making your decision.
Ultimately, the choice between a mummy bag and a quilt depends on your personal preferences, sleeping habits, weight considerations, and the weather conditions you anticipate encountering. Both options have their strengths and weaknesses, so consider your specific needs and priorities when making your decision.

Temperature ratings
The temperature rating of a sleeping bag is a crucial factor in determining its suitability for a particular trip. Mummy bags are designed to be lightweight and compact, and their tapered shape helps achieve this. However, this shape also means that they can feel restrictive, particularly for side sleepers or those who move a lot in their sleep.
When considering the temperature rating, it is important to balance warmth with weight. A bag's temperature rating indicates the lowest temperature at which it will keep you warm. For example, the Feathered Friends Flicker 40 UL has a 40°F temperature rating, making it suitable for thru-hikers or backpackers who need a lightweight bag that can handle a range of conditions. The Feathered Friends Hummingbird UL, on the other hand, offers an unparalleled warmth-to-weight ratio, providing exceptional warmth despite its lightweight design.
Some mummy bags offer more spacious designs, such as the Nemo Disco 15, which provides ample space at the foot of the bag. While the extra space may appeal to those who want some wiggle room, it can also mean a compromise on warmth, as the bag's shape is less thermally efficient. The Nemo Tempo 20 Synthetic is another bag that offers a roomier fit, with a loft and comfort similar to down. It is a good budget option for those who want to stay warm in humid conditions.
For those who prioritise warmth and thermal efficiency, a highly tapered mummy bag might be the best choice. The Rab Neutrino 400 has a comfort rating of -1°C, making it suitable for colder conditions. The Western Mountaineering Kodiak MF is another bag that has lived up to its 0°F temperature rating, according to testers.
It is important to consider the temperature ratings of sleeping bags in relation to the expected temperatures of your trip. Mummy bags offer a range of temperature ratings, from mild conditions to freezing temperatures, so choosing one that matches your needs is essential.

Weight and packed size
When choosing a mummy sleeping bag, weight and packed size are important considerations. Mummy bags are known for being lightweight and compact, making them a popular choice for backpacking. They have less internal air to heat up and require less material and insulation than other types of sleeping bags.
The Zpacks Mummy Sleeping Bag is one of the lightest options on the market, weighing just 1 pound and 11.7 ounces. It offers a great warmth-to-weight ratio and is ideal for hikers looking for a warm and lightweight option. The bag features a hood and a full-length zipper, which are not common in ultralight mummy bags. The included dry bag adds 0.9 ounces to the weight and helps keep the sleeping bag dry and protected.
The Teton TrailHead 20˚F Mummy Sleeping Bag is another lightweight option, known for its packability. It has oversized dimensions for a comfortable fit, while the synthetic fill retains heat without adding bulk. It comes with a stuff sack for easy packing and carrying, making it a great choice for backpacking or car camping.
For those seeking an even lighter option, quilts have gained popularity among backpackers due to their lightweight and compact nature. However, quilts may not be suitable for everyone, as they can be drafty for those who move a lot in their sleep. Mummy bags with extra width in the middle are also available for side sleepers who prefer more room to move around.
Ultimately, the weight and packed size of a mummy sleeping bag depend on the specific product and its features. Some bags focus on comfort and internal space, while others prioritize being lightweight and compact. It's important to consider your personal preferences and needs when choosing the best mummy sleeping bag for your outdoor adventures.

Price
The price of a mummy sleeping bag varies depending on its features, quality, and brand. Some options are available for under $80, such as the Klymit Wild Aspen 0, the Coleman 0 degree, and the Kelty Galactic. However, these bags may not offer the same level of warmth, comfort, or durability as higher-priced options.
For those seeking a good balance between price and performance, the Mountain Hardwear Bishop Pass 15 is a popular choice. It offers a solid warmth-to-weight ratio, packs relatively small, and is more affordable than ultra-premium bags without compromising on essential features.
If you're willing to stretch your budget further, there are several high-end options to consider. The Feathered Friends Hummingbird UL, for example, boasts an unparalleled warmth-to-weight ratio and is crafted from ultra-high-fill-power down, but it comes with a matching ultra-high price tag. The Western Mountaineering MegaLite is another premium choice, known for its luxurious loft and spacious design, though it may not be suitable for those who prefer a tighter mummy shape.
For side sleepers, the Big Agnes Sidewinder SL 20° is a high-quality option that comes with a limited warranty. It is designed with a wider cut, additional synthetic fill in the hip areas, and a pillow sleeve, making it ideal for those who shift positions while sleeping. This bag is also significantly lighter than its competitors, but it does come at a higher price.
Ultimately, the price of a mummy sleeping bag depends on your specific needs and preferences. While some bags offer exceptional performance and comfort, they may not be necessary for casual campers. It's important to consider factors such as temperature ratings, weight, and spaciousness before making a decision, as these will impact both the price and your overall satisfaction with the product.

Shape and comfort
The shape of a mummy sleeping bag is an important factor to consider when choosing one. Mummy sleeping bags are generally tapered, which means they are narrower at the feet than at the torso and shoulders. This tapered shape helps to retain body heat and keep the sleeper warm. However, some people may find the tapered shape restrictive, especially if they tend to move around a lot in their sleep. For side sleepers, a bag with a more innovative shape, such as the Nemo Disco, the Big Agnes Sidewinder, or the Montbell Down Hugger 650 #1, might be a better option. These bags have a more spacious design that allows sleepers to move around more freely without feeling constrained.
The comfort of a mummy sleeping bag is also an important consideration. Sleeping bags with a higher fill power, such as those filled with goose down or high-quality synthetic materials, tend to be softer, plusher, and better at retaining body heat. The Feathered Friends Hummingbird UL, for example, features an ultra-high fill power that provides an unparalleled warmth-to-weight ratio and a cozy night's sleep. However, it comes with a matching ultra-high price point. Other features that contribute to comfort include the size and shape of the bag, the presence of a hood or draft collar, and the softness of the materials used. For example, the Nemo Tempo 20 Synthetic offers loft and comfort similar to down at a more affordable price point.
The Nemo Disco is a notable option for those seeking comfort. Unlike traditional mummy bags, it features a "spoon"-shaped concept that provides extra width in the elbows and knees, allowing sleepers to roll around without feeling restricted. Additionally, it includes features such as "Thermo Gill" vents that release hot air in warm conditions, an oversized draft collar, and a built-in pillow sleeve. The Mountain Hardwear Bishop Pass 15 is another option that offers a balance of performance characteristics. It combines 650-fill power down with a simple mummy design, providing impressive warmth-to-weight ratio and packability at a more affordable price point.
When it comes to comfort, it's important to consider your sleeping style and preferences. Side sleepers, for instance, may prefer bags with extra padding at the hips and feet, such as the Big Agnes Sidewinder, which features synthetic insulation at these contact points. Additionally, the noisiness of the fabric can be a factor that affects comfort. Some fabrics, like the Pertex Endurance shell of the Feathered Friends Hummingbird UL, can be crinkly and disturb light sleepers. In such cases, choosing a bag with a quieter fabric or using earplugs can be a solution.
Lastly, it's worth mentioning that some people prefer the coziness and simplicity of a lightweight mummy bag, while others may opt for quilts or other alternatives. Mummy bags are generally favoured for their warmth and weight balance, especially in colder conditions. However, quilts can be a viable option for warm nights as they are lightweight, focus the insulation on top of the body, and ventilate well. Ultimately, the decision between a mummy bag, a quilt, or another alternative comes down to personal preference and the specific needs of the individual.
