Features to Consider for a Sleeping Bag

Buying a particular down sleeping bag is not a walk in the park; those who have ever found themselves in this situation can confirm this. Each down sleeping bag has its strengths and weaknesses which make the difference between them.

Having this in mind will act as a highway that will somehow lead you to buy a particular type of down sleeping bag. The primary focus here is to find a down sleeping bag that you will not regret having spent your hard earned cash on.

Two people covering sleeping bag

Having said that, the first consideration you should make is the season you are planning to use the sleeping bag in. Will you be using the sleeping bag mostly in summer or winter? Will you be using your sleeping bag during spring or autumn so as to go for the 3 season sleeping bag?

Apart from the factors discussed above, there are also some very crucial features that one needs to pay much attention to before deciding on which sleeping bag to spend their money on.


Two main factors determine the size of a sleeping bag. First is the comfort and then the size of the person who will be sleeping in the bag. A huge sleeping bag will lose so much heat, and on the other hand, a bag offering a snugger fit to its user will easily retain the heat.

Best down sleeping bag

Therefore depending on your size and how comfortable you want to feel while using your sleeping bag, you will be able to make the right decision.


Another very important factor that should not be overlooked is the shape of the down sleeping bag. The shape of the sleeping bag one will purchase is a personal choice as long as you will be comfortable using a particular shaped sleeping bag.

There are rectangular, semi-rectangular and the double sleeping bag which is basically a wider version of the standard rectangular sleeping bag. Rectangular sleeping bags offer the maximum comfort as well as roominess.

If you want to use your bag for both camping and backpacking, then go for the semi-rectangular shaped bags. Their tapered design is very efficient in offering greater warmth and enough room for a comfortable sleep.

For those planning to do some car camping and backpacking, the mummy shaped bags would be ideal for you. With the hip widths and narrow shoulders of the mummy bags, the bags will offer maximum warmth and weigh less.

Temperature ratings

The temperature ratings on all sleeping bags indicate the lowest temperature that each bag has been designed to handle. You should, however, take temperature ratings with a grain of salt because there happens to be no standard way of determining the ratings.

Sleeping bag temperature rating

This, therefore, means that manufacturers have the freedom to say whatever they want about the warmth of their bags. The EN 13537 standardized rating system has been widely accepted across Europe, and some US bag manufacturers have also adopted it.

The insulation type

It is very true that out of every 10 campers buying sleeping bags, 7 will go for the synthetic insulated sleeping bags. This is majorly because of their affordable price tags. They dry quickly and are known to insulate when wet as well.

Sleeping Bag Material

On the other hand, most other people will also go for sleeping bags that are down insulated because they are more durable and can be compressed more compared to the synthetic sleeping bags.


It is also very important to consider the added accessories that the bag comes with. It is worth keeping in mind accessories like the zip. Does the zip extend the entire length of the bag? What of the hood? Does it have a hood and does the hood naturally hug the head? You don’t want to lose a lot of heat through the head, and this is why the hood is necessary.

Sleeping bag accessories

The hood will help stop heat from radiating away from your head. It is also worth noting whether the loop tabs and hook cover the zip. This is important because it can additionally protect the zip and prevent it from catching on the zip’s surroundings.

Availability of a staff sack and a storage sack

Even though the staff sack could be sold separately, many bags come with theirs free of charge for easy transportation of the bag. If the sleeping bag you are purchasing has this staff sack free of charge and has all the other features discussed above, why not go for it?

A very important tip on how to prolong the life of your sleeping bag is to hang it in the garage or store it loosely in the storage sack. It should not be stored rolled up tightly in a staff sack. So if the sleeping bag you are buying comes with a storage sack in addition to the other vital features then simply buy that storage bag.

Storage Stack

After going through all these considerations, you will be capable of making the best decision when it comes to buying the best down sleeping bags.
