Choosing A Sleeping Bag: Factors For A Good Night's Sleep

how to buy the best sleeping bag

When it comes to buying a sleeping bag, there are a few key factors to consider. Firstly, the type of activity you'll be using it for—whether it's car camping or backpacking—will influence your decision. Backpacking sleeping bags need to be lightweight and packable, while car camping bags can be roomier and heavier. The temperature rating is another crucial factor; choose a bag with a lower temperature rating than you expect to encounter, and consider features like a snug-fitting hood for extra warmth. Other features to look out for include zipper styles, stash pockets, and the type of shell and lining materials. It's also important to consider your budget, as prices can vary significantly. Finally, don't forget to think about your personal preferences, such as your sleeping style and comfort needs.

Sleeping bag types: backpacking vs camping

When choosing a sleeping bag, the biggest differentiating factor is the location and how far you will be from motorized transportation. If you're camping near your car, you can opt for a heavier, bulkier, and more comfortable sleeping bag. On the other hand, if you're backpacking or venturing into the backcountry, a lightweight, compact, and warm sleeping bag is ideal.

Sleeping Bag Types: Backpacking vs. Camping

Backpacking Sleeping Bags

Backpacking sleeping bags are designed with weight and packed size in mind. They are typically more lightweight and pack down smaller than camping sleeping bags. These bags are often more expensive due to their lighter weight and compressibility. The shape of backpacking sleeping bags tends to be more sleek and snug, which helps retain heat and reduce weight. The most common shape is the “mummy” type, which has a slim cut and a contoured hood for added warmth. Some backpacking bags also have a “semirectangular” or "modified mummy" shape, offering a balance between warmth and roominess.

When choosing a backpacking sleeping bag, consider the temperature rating, which indicates the lowest temperature the bag is designed to keep an "average sleeper" warm. It's recommended to select a bag with a lower temperature rating than the expected nighttime temperature, as you can always unzip the bag if it gets too warm. Backpacking bags are often rated according to the industry-standard EN test, which provides a consistent measure of warmth.

Camping Sleeping Bags

Camping sleeping bags, also known as "car camping" bags, prioritize comfort and cost savings over weight and packed size. These bags are typically heavier and bulkier, making them ideal for camping near your vehicle. Camping sleeping bags often have a rectangular shape, providing ample room to stretch out and roll over. The Alps OutdoorZ Redwood is a popular choice for car camping due to its rugged design, cozy flannel interior, and warmth, although it is too heavy for backpacking.

When selecting a camping sleeping bag, you have the freedom to choose the warmest and roomiest option within your budget without worrying as much about weight and bulk. Camping sleeping bags may not require the same level of performance as backpacking bags, so the primary considerations are warmth, size, and budget.

Temperature ratings

The temperature rating of a sleeping bag is one of the most important factors to consider when buying one. It will determine how warm and comfortable you will be when sleeping outdoors.

When choosing a bag, it's recommended to go for one with a lower temperature rating than the lowest nighttime temperature you expect to encounter. For example, if you're camping in a location where the temperature drops to 5°C, you should consider a bag with a 0°C rating. This will ensure you stay warm and toasty throughout the night.

Some bags have a comfort rating, which is the temperature at which a standard female sleeper can expect to sleep comfortably in a relaxed position. There are also male comfort ratings, which are typically higher, as men tend to sleep warmer than women. If you consider yourself a cold sleeper, it's best to go for a bag with a lower temperature rating.

When it comes to backpacking, weight is also a crucial factor. A good backpacking sleeping bag should be lightweight and packable, while still providing ample warmth. Down bags are usually the best choice for backpacking as they are warm and lightweight. Synthetic bags are also an option for basecamp scenarios, as they are often more affordable.

Materials and weight

The materials and weight of a sleeping bag are important factors to consider when purchasing one. The outer fabric of a sleeping bag is typically made of durable polyester or nylon with a durable water repellent (DWR) finish to protect the insulation inside the shell from dampness. The inner materials are designed to be soft and warm.

When it comes to weight, the purpose of your sleeping bag will determine the best option for you. If you're car camping, weight is less of a concern, and you can choose a warmer and roomier option. The Alps OutdoorZ Redwood, for example, is a great option for car camping as it's rugged, comfortable, and warm, but it's too heavy for backpacking. On the other hand, if you're backpacking, you'll want to prioritize a lightweight sleeping bag that's easy to carry and pack. The Western Mountaineering MegaLite and AlpinLite are excellent lightweight options for backpackers.

If you plan to use your sleeping bag for both car camping and backpacking, it's best to choose a backpacking-style bag that is lightweight and packable. The Zpacks Classic 30-degree sleeping bag, for instance, weighs just 14 ounces and is made with water-resistant down. The Feathered Friends Hummingbird UL 30 is another lightweight option at about 22 ounces.

Weight can also be a factor when considering the temperature rating of a sleeping bag. A warmer bag will generally be heavier, and vice versa. Additionally, the fit of the sleeping bag can impact weight, as a bag that is too spacious may not retain heat as efficiently as a bag that is more fitted to your body.

Finally, the materials used in the sleeping bag can impact its weight. Down bags, for example, tend to be lighter than synthetic bags. However, synthetic bags can be a more affordable option.

Size and shape

The size and shape of a sleeping bag are important factors to consider when purchasing one. The intended use of the bag will largely determine the size and shape you should go for.

If you're going camping and your vehicle will be doing the heavy lifting, you can go for a spacious sleeping bag. Camping sleeping bags generally offer plenty of room to move around in. The Alps OutdoorZ Redwood sleeping bag, for instance, has spacious dimensions and a rectangular shape that testers found super comfortable. The REI Co-op Siesta Hooded 20 is another option that comes in two sizes: regular and long. It has a roomier feel than most mummy-style options and is ideal for people with broad shoulders and narrower hips.

On the other hand, if you're going backpacking, you'll want to go for a lightweight sleeping bag that packs up into a small stuff sack. The Western Mountaineering MegaLite and the Western Mountaineering AlpinLite, for instance, are lightweight and perfect for backpacking. The Zpacks Classic 30 is another great option, weighing just 14 ounces. It has a bottom zipper, which allows for maximum heat retention, and you can turn with the bag or inside it regardless of whether you're a back or side sleeper. The Feathered Friends Hummingbird UL 30 is a narrower bag, so it saves weight and is more efficient.

Additionally, if you're a side sleeper, you'll want to look for a bag with a roomy design. The Sea to Summit Spark 15, for example, has a handy snap system at the neck that allows the bag to be used as a quilt when fully unzipped.

It's also worth noting that sleeping bags come in different sizes for adults and children. Kids' sleeping bags are simply shorter, smaller, and more affordable variations of adult sleeping bags.

Zippers and pockets

Zippers are an important feature of sleeping bags, and there are a few things to consider when looking at this aspect. Firstly, if you're planning on backpacking, you'll want a bag with a zipper on the bottom to retain maximum heat, and no zipper at the top, as this is where most heat escapes. Bags with more than one zipper slider are ideal as they allow for easy ventilation adjustments. Additionally, some bags have features to prevent zipper snagging, such as a full-length guard or a cover over the zipper.

If you're car camping, you have more flexibility as you don't need to worry about weight or packing your bag into a small space. In this case, you might prefer a bag with a wrap-around zipper, which can double as a picnic blanket or quilt. You could also consider double sleeping bags made for two people, or rectangular bags designed to zip together, as long as they are the same model and brand. If you're a couple with different preferences, you could buy two bags with right- or left-zip configurations and zip them together.

Some sleeping bags also come with pockets, which can be useful for storing small items like a watch or lip balm. If you're looking for a lightweight bag, be aware that ultralight bags tend to have finicky zips that can rip the thin fabric.
