There are a lot of debates about sleeping bags and blankets. Some people swear by sleeping bags, while others find them too constricting.

Which one is the best for you? Let’s explore it with the help of the following comparison factors:


Sleeping bags are typically warmer than blankets because they are designed to trap your body heat. They usually have a layer of insulation that helps keep the heat in, making them ideal for camping in colder weather.

With fewer air pockets, sleeping bags are good at keeping heat and giving you a mother’s lap feeling.

On the other hand, blankets are not as good at trapping heat because they are typically made from thinner materials and more air pockets. This makes them better for use in warmer weather or inside a tent where it is already warm.

Warmth-to-Weight Ratio

Camping gear is usually compared on the basis of the warmth-to-weight ratio. Sleeping bags are usually heavier than blankets, but they pack down smaller and provide good insulation for their weight.


Compared to blankets, Sleeping bags can be more comfortable because they are designed to fit your body snugly. This can help you stay warm and prevent you from rolling off your sleeping pad during the night.


Sleeping bags are more versatile in terms of:

Different Sizes and Shapes

  • Rectangular Bags: They are the most common type of sleeping bag and are usually less expensive. They offer more space to move around and can be unzipped to be used as a quilt. Some campers unzip extra bags and use them as floor mats.
  • Mummy Bags: They are designed to fit your body snugly and trap heat more effectively. A great option for cold-weather camping.
  • Semi-Rectangular Bags or Modified Mummy Bags: They are a cross between rectangular and mummy bags. They offer more space than mummy bags but are still fairly warm.
  • Couple Bag: It is a type of sleeping bag that is designed to fit two people. Usually larger and heavier than other types of sleeping bags.
  • Child Sleeping Bag: It is specifically made for kids. They are often smaller and lighter than adult sleeping bags.
  • Oversized Double Bag: Some bags come with a “zipping together” feature that makes them a giant double bag. A perfect choice for mothers and newborns, couples, or simply for those who want a bigger lap.

So, you can choose the one which suits you the most in terms of comfort and your need.

Different Weather Situations

You can use sleeping bags in a variety of different weather conditions. There are lightweight options for summer. The 4-season bags are a definite choice for frequent campers who can use them in any weather condition.

However, blankets are typically only used in warmer weather because they don’t provide enough insulation in colder temperatures.

Different Types of Insulation

  • Down Sleeping Bags: Filled with duck or goose feathers. They are typically lighter and more compressible than synthetic sleeping bags but are more expensive.
  • Synthetic Sleeping Bags: Stuffed with man-made fibers such as polyester. They are usually less expensive, non-allergenic, and dry fast than down sleeping bags but are not as compressible.


The feature of compressing and packing better than blankets makes sleeping bags more portable. This is especially important for backpackers and hikers who need to save space in their packs.

Some additional features like carrying cases, stash pockets, packing rolls, hoodies, and built-in pillows, make sleeping bags portable and must-have travel gear for RVs. This makes them easy to store and transport.

Ease of use

Sleeping buddies are typically easier to use than blankets. You can simply unzip them and climb in.

Blankets, on the other hand, can be more difficult to use. You may have to fold them or tuck them in to stay warm during the night.

Water-Resistance and Fire-Resistance

Sleeping bags offer better protection against the wind, frost, and rain than blankets. This is because they have a water-resistant shell that can help keep you dry and warm.

Blankets, on the other hand, are not typically water-resistant.

Sleeping bags that are made from synthetic materials are less flammable than natural fibers.

For Kids

Sleeping bags are usually a better option for kids than blankets. This is because they are less likely to roll off their Sleeping bag and be at a constant temperature during the night.

For Allergy-Sufferers

Besides kids, Sleeping bags can be a good option for people who suffer from allergies because they are less likely to catch dirt and dust when in use or stored as blankets do.

With all the above advantages, sleeping bags come with some downsides like they are comparatively more expensive, and some people find them too constricting. Blankets can be a great alternative to sleeping bags, as they are much cheaper and more durable.

Which one should you choose? It depends on your needs and preferences. If you need a warm and comfortable place to sleep, go for a Sleeping bag. If you want a cheaper and more durable option, go for a blanket.

I hope this article helped you decide which one is the best for you. Sleeping bags or blankets, the choice is yours!

Happy camping!
