What To Look For - The Factors We Use to Rate Sleeping Bags
We keep these factors in mind when rating sleeping bags to ensure we recommend the best sleeping bag that provides all the features you need for a backpacking trip.
Comfort
Sleeping bag comfort rating refers to the optimum temperature at which the sleeping bag will keep you warm and comfortable when sleeping.
Weight
When deciding on a sleeping bag for backpacking, you should always try to get the lightest one you can afford.
A lightweight sleeping bag that has an excellent warmth-to-weight ratio will be able to keep you warm and comfortable at night and will be easier to carry in a backpack as it will not weigh you down.
High-fill power-down sleeping bags and low denier shell fabrics are lightweight, compressible, and warm enough to keep you comfortable at night.
Warmth
Sleeping bag temperature ratings are among the most important factors to consider when choosing a backpacking sleeping bag. The temperature rating represents the lowest temperature when a sleeping bag can keep you warm.
The temperature rating you choose will depend on the season and the temperature, the temperature of the environment you'll be using the sleeping bag in, and the temperature you'll be comfortable at when sleeping.
Packed Size
As a backpacker, you want a sleeping bag that will pack very small so that it can fit into your backpack without taking too much space.
The packed size will also help you determine the comfort level you'll be carrying in a sleeping bag.
You want a big enough bag to cover you cozily when you sleep and fold to a compact size when packed for carrying a backpack.
A down sleeping bag that comes with lightweight materials will pack very small, and a compression sack can also help reduce the packed size of the bag.
Fill Power
Sleeping bag fill power determines the loft or fluffiness of a down sleeping bag. The higher the fill power of a sleeping bag, the more air the down can trap and the more warmth and lightweight it will be.
Shell Fabric
The shell fabric of a sleeping bag will significantly determine the warmth, weight, price, and durability of the pack. Nylon, polyester, and taffeta are mainly used across all sleeping bags, from budget to high-end sleeping bags. These materials are breathable and soft on the skin. Taffeta is the highest quality sleeping bag fabric but takes longer to dry, making it less suitable for colder weather.
Versatility
A versatile sleeping bag will have the ability to adapt to many different situations while offering you everything you need to stay warm and comfortable at night.
Features & Design
More features equal more comfort and more value for money. Features such as breathability, waterproofness, foot box, lightweight design, and packablility will come in handy for warmth, comfort, and flexibility.
The design of a sleeping bag can also affect its warmth and comfort of a sleeping bag. Mummy sleeping bags are lighter, warmer, and more suitable for colder nights than rectangular sleeping bags.
Female - Specific Features
On average, women usually feel colder than men. There are specific features that women will need in a sleeping bag to stay more comfortable.
Some of these features include more space in the elbows, extra room in the chest, additional fill in the foot box, and enough room to curl, among others.

Backpacking Sleeping Bag FAQ
Are Sleeping Bags Machine Washable?
Most sleeping bags are machine washable as long as you use a top-loading machine without an agitator or a front loading washer. Most home front loaders are usually small and energy-efficient and may not give enough room for the sleeping bag to tumble and clean thoroughly.
What Is a Good Weight for a Backpacking Sleeping Bag?
A backpacking sleeping bag should be very lightweight and weigh 2 or 3 pounds to carry in your backpack without adding a weight that can drag you down.
Should I Get a Down or Synthetic Sleeping Bag?
Down sleeping bags are lighter than synthetic bags and tend to be warmer and last longer. As a backpacker, you should get a down sleeping bag because it will save you a lot of weight and stay warm and comfortable at night.
Are Sleeping Bag Liners Necessary?
Sleeping bag liners are not necessary but will help protect your sleeping bag from dirt, sweat, and body oils which can affect the insulation, feel, and durability of the sleeping bag.
