Best Sleeping Bags for Backpackers

If you have spent a night in a cold area where no heating is available especially while camping or backpacking, then you will fully understand how important a good quality sleeping bag is. It won’t just keep you warm but also help you sleep peacefully and comfortably. Without a doubt, it is one of the most important items to consider for any backpacking trip.

To help you choose the best sleeping bag, we have put together a mini guide and recommended some top-notch sleeping bags, so your body can get the rest it needs.

Here are some things that you must consider before buying a sleeping bag for backpacking:

1. EN Ratings

EN stands for European Norm, which are the ratings that are set consistent across the sleeping bag industry. These can also be referred to as comfort ratings or temperature ratings. The lower the limit, the higher the risks there will be.

  • Comfort Range

Upper limit: 30°F

Lower limit: 0°F

  • Transition Range

Upper limit: 20°F

Lower limit: -6°F

  • Extreme Range (Risk Range)

Upper limit: -12°F

Lower limit: -24°F

Sleeping bags having EN lower limits between 10°F and 30°F are normally considered as standard ones and good for 3 seasons: spring, summer, and fall. Make sure you choose a bag according to the place you are backpacking for.

2. Price

A sleeping bag will probably be one of the most expensive accessories in your backpack. If you can’t afford one, you can borrow it from someone or consider the backpacking rental services.  But if you are a regular backpacker who wants to enjoy your own things then you should invest in a high-quality sleeping bag.

High-end sleeping bags start at $500 depending on the quality but you can also go for budget sleeping bags that get down around $150 or below.

3. Weight

One of the heaviest things in your backpack would surely be a sleeping bag, and you have to make sure that you inspect the comfort and warmth level of a sleeping bag before getting one. No doubt, it will be quite tough to carry a heavy backpack on a hike but you do not want to compromise on warmth either.

Consider the EN ratings of a bag; the lower the ratings, the heavier the sleeping bag will be.

4. Storage

It is recommended that you never store your sleeping bag compressed for long periods of time because it can damage the insulation and its ability to keep you warm. Upon reaching the destination, you should take the sleeping bag out of your backpack and hang or spread it out straight.

5. Type of design

  • Mummy

As the name implies, mummy sleeping bags have a close fitting and usually a hood to keep you warm in cold areas.

  • Rectangle

Rectangle sleeping bags are cheaper than other types and are a good option to be used in warm temperatures. They have more room to move around. However, these bags should not be your first preference to use in frosty conditions.

  • Hybrid

These are a combination of mummy and rectangle sleeping bags. They are shaped rectangular with a mummy design hood so you can stay warmer and have enough room to move around. This is less common than the two designs mentioned above.

  • Quilt

If you want comfort like home, then you should get a quilt sleeping bag that is similar to a quilt at your home but made of sleeping bag material.
