Last update: 2022-08-04

When it comes to sleeping bags, one often feels overwhelmed by available choices regarding the shape, size, and built-in features. Mummy sleeping bags have long been the most prominent type in the market. The mummy sleeping bag is well-known for its ultimate design that maximizes heat.

I have compiled a list of best mummy sleeping bags for camping & backpacking in which you probably will find your most suitable one. Check them below!

Best Synthetic Mummy Sleeping Bags


Top Pick

  • Fiber Fill is skin-friendly
  • Both cover and fill are water resistant
  • Great design brings best comfortability
  • Budget-friendly
  • The zipper catches the outer fabric sometimes
  • A bit bulky

If you are not impressed by the weight of this sleeping bag, then the 200G/㎡ Hollow fiber fill could make a difference. Fiber-fill offers a myriad of benefits. It is suitable for people with allergies or inflammatory diseases such as asthma.

Plus, synthetic sleeping bags are washable and require minimum preservation. Both the cover and fiber-fill are water-resistant, which brings great relief when you have to camp overnight in damp & wet conditions.

This item features an SBS zipper that allows you to adjust the heat inside the sleeping bag. Vent on the side and hood on the top are designed to deliver utmost comfortability and warmth.

What makes me disappointed about this item is the fact that the zipper doesn’t work very well. Yes, it seems to be a common flaw of affordable sleeping bags. Still, having the zipper snagged on the outer fabric and refused to move is annoying sometimes.

Product Specifications

Weight (lbs) (Short/Regular/Long)2.8 lbs
Insulation200G/㎡ Hollow Fiber fill
Temperature rating °F (Survival/Lower/Comfort)20/35/40F

As the temperature rating is about 35 to 40F, I think WINNER OUTFITTERS Mummy Sleeping Bag is an excellent companion for campers and backpackers in May-to-October trips. Those who look for reliable and reasonably priced sleeping bags should try this one.

Coleman Adult Mummy Sleeping Bag

  • Great for car camping
  • 200G/㎡ Hollow Fiber Fill, which reduces the temperature rating, keep you toasty warm all night
  • Budget-friendly
  • Quite bulky for backpacking
  • For tall adults, this bag could be a bit tight

Coleman has made a compatible mummy sleeping bag for car camping. Though the weight of 2.8 lbs is not bad for pack backing, I would personally not recommend that since this sleeping bag is super bulky. It can take up ample space in your backpack.

Regarding the ability to keep warm, a bulky sleeping bag turns out to be useful. With 200G/㎡ Hollow Fiber Fill, coupled with draft tubes and draft collars, Coleman Sleeping Bag excels at preventing heat loss during the cold night.

The limit temperature rating of this bag is relatively low, from 0 to 10F. This means you could get freeze using Coleman bag when the temperature drops below 10F. Other than that, this mummy sleeping bag is an excellent choice for camping trips in late autumn or mild winter.

This product nails what seems to be impossible with many sleeping bags – the zippers. This item’s zippers work perfectly even when you are inside the bag. No more 10-minute struggle each time you want to pull the zippers up and down.

The hood part is also my favorite since you can put a pillow inside and use the strings to adjust your comfortability.

This mummy sleeping bag is ideal for small kids and average-built adults given its size of 32" x 82". Those who are tall might find it hard to move around a bit.

Product specifications

Size (packed)32" x 82"
Weight (lbs) (Short/Regular/Long)2.8 lbs
Insulation200G/㎡ Hollow Fiber fill
Temperature rating °F (Survival/Lower/Comfort)0 degree F to 10 degree F

Coleman Adult Mummy Sleeping Bag is a real deal for casual car campers who don’t mind weighty sleeping bag and often aim for short-distance trips.

I recommend buying this bag instead of those high-end ones, especially when you don’t want to overspend your money and accept a bulky yet high-quality bag.

Best Down Mummy Sleeping Bags

Hyke & Byke Eolus 15 °F Down Sleeping Bag

Hyke & Byke Eolus 15 °F Down Sleeping Bag
Hyke & Byke Eolus 15 °F Down Sleeping Bag

  • Reasonably priced with great quality and premium 800 fill power goose down
  • Highly compressible
  • Comes with various colors and sizes
  • DWR-treated Down fill is washable but should be limited.
  • Zippers are not snag-free

Down insulation is regarded as one of the most expensive fills in the market. As a result, the price of down fill sleeping bags is often not wallet-friendly.

Fortunately for budget backpackers, Hyke & Byke has introduced its Eolus 15 °F Down Sleeping Bag that nails both price and quality. You will be surprised by the performance of this sleeping bag even though it doesn’t cost you an arm and a leg like other down fill sleeping bags.

You are safe to use the Eolus 15 °F Down Sleeping Bag when the temperature is within the comfort zone, which is from 30 to 50F. The 800 FP 90/10 Goose Down can keep you comfortably warm.

In fact, you might want to open the bag to expel the heat once in a while. If you're going to use this sleeping bag down to its limit rating, which is 15F, it is advised to wear enough warm clothes and top up to stay warm.

To enjoy its greatest warm, you’d better fluff it up before use as down fill isn’t as excellent at insulation when it is compressed.

The weight is not brilliant, as the more prominent the bag is, the heavier it becomes. 3.2 lbs might seem to be a bit too bulky for backpacking trips. However, with car camping, when the weight isn’t a big deal, this bag makes an excellent choice.

The sleeping bag’s cover is DWR treated, so it will allow you to stay in most wet condition. What makes me worry is that the down is not treated. And the warranty doesn’t cover any damages if you mess up when cleaning the bag.

So if I were you, I would rather find a cleaning service than do it myself. This could be a significant drawback because you have to pay attention to the preservation in the long term.

One more drawback is the zipper. Again, it is not snag-free. The good news is that snagging doesn’t happen too frequently.

Product specifications

Size (packed)Fits individual from 5” to 6”6
Weight (lbs) (Short/Regular/Long)2.8/ 3.0/3.2 lbs
Insulation800 FP 90/10 Goose Down
Temperature rating °F (Survival/Lower/Comfort)15/30/50 F

The price of this bag is brilliant. If you are a fan of down-filled sleeping bags, you should not ignore this wallet-friendly option.

Hyke & Byke Crestone Hammock Compatible Down Sleeping Bag

Hyke & Byke Crestone Hammock Compatible Down Sleeping Bag

  • Very light and compact
  • The shell material is tough
  • Zippers work well
  • 550 fill power duck down has less insulating ability

Hyke & Byke is a rapidly growing company for outdoor gears with a defined goal: to supply outdoor addicts with affordable products. Most of their products are reasonably priced and versatile.

Like most of the backpackers, I try to save weight and space inside my backpack. Thus if I ever have to choose a mummy sleeping bag, I’d go for Hyke & Byke Crestone Hammock Compatible Down Sleeping Bag. Why? This sleeping bag weighs up to 1.9 lbs – an ideal number for a backpacking sleeping bag.

Now, there is one factor that contributes to the affordability and portability of this sleeping bag. It is the 550 fill power duck down. First, duck down comes with a low price. Plus, the 550 fill power may not be the best insulation to stay warm when the temperature drops lower than 30°F. However, it tremendously reduces the weight of the bag.

As you can see this bag offers 550 fill power duck down. Duck down is often weightier than goose one. Its ability to keep warm is also lower. Nevertheless, both Hyke & Byke Eolus 15 °F Down Sleeping Bag and Hyke & Byke Crestone Hammock Compatible Down Sleeping Bag have the same temperature rating. Why?

As I concern, many factors contribute to the temperature rating and the ability to keep warm of a sleeping bag. In theory, the temperature rating of these two bags is the same, but in reality, the Crestone Hammock is more vulnerable to external stimuli. So, you may have to wait a bit longer to feel the warmth inside the bag.

One thing that most people complain about budget-friendly sleeping bags is that the fabric is cheaply made and easy to rip apart. I don’t see any similar problem in Hyke & Byke Crestone Hammock Compatible Down Sleeping Bag. The material is well made and tough, which prevents you from accidentally ripping it off. There is also no trouble pulling the zipper up and down.

This sleeping bag is compatible with hammock camping, mostly because it is well designed. The bag includes a flap at the bottom that conceals the hole created by the hammock rope. This is an excellent feature since it averts cold air from getting in.

Product specifications

Size (packed)Regular (Individuals up to 6'), and Long / Tall / XL (Individuals up to 6'6").
Weight (lbs) (Short/Regular/Long)1.7/ 1.8/ 1.9 lbs

All in all, this is an excellent product of value. Travelers who want to own a light, budget-friendly sleeping bag for their upcoming hammock camping should consider buying this item.

  • High-end product comes with great features to maintain heat
  • Suitable for a 3-season sleeping bag including autumn, spring and winter
  • Compressible and lightweight, suitable for backpacking
  • No built-in loop to hang the bag
  • You have to unzip a bit to use your hands outside of the bag

It took me many freezing nights to come to the decision to pay over $500 for a sleeping bag. After that, I have to admit this is the wisest decision I have ever made. The price isn’t ideal, but the quality counteracts for all.

The survival temperature rating of this bag is under 10F. That means you probably freeze sleeping in this bag without additional layers and clothes at that temperature.

Other than that, the bag serves you well within the safe zone. One thing worth to mention is the loft. Thanks to 850+ fill power and draft collars, the Western Mountaineering 10 Degree Versalite Sleeping Bag is able to maintain warm all night long. This product has 6” loft, which is excellent at keeping heat inside.

I normally hang my sleeping bag up when the sun is out. Unfortunately, this bag doesn’t include a loop at the bottom to let me do so. I also don’t like the fact that the opening is a bit narrow. So, if I want to stick my hands out to eat, I need to unzip a bit.

Product specifications:

SizeFits Individuals from 6' to 6'6"
Weight (lbs) (Short/Regular/Long)1lb 14oz/ 2lb/ 2lb 2oz
Insulation850+ fill power

Are mummy sleeping bags comfortable?

I had mixed feeling when I first started researching about mummy sleeping bags. Some people say mummy shape is comfortable; others seem to disagree. As I have gained more experiences with this particular type of sleeping bags, I am now more confident about addressing this question.

Mummy sleeping bags adopt the Egyptian mummy shape. This shape, by design, is tight and often makes some people feel less comfortable because they can’t move freely. So, the answer is it varies from person to person.

When it comes to the ability to maintain heat, mummy sleeping bags are unbeatable. Thanks to the narrow shoulder and hip, these bags trap warmth inside while stopping cold air from outside to get in. Mummy sleeping bags are excellent choices for intense backpacking and camping trips under unfavorable conditions.

How heavy should a sleeping bag be for backpacking?

Backpacking often involves long walking and hiking. As a result, backpackers tend to pack light and remove unnecessary gears.

Having a lightweight sleeping bag, for that reason, is vitally important since it helps reduce the weight of your backpack. The question is how heavy a sleeping bag should be.

The answer to this question varies from person to person. Some people may argue that as long as you are physically fit, you can carry a sleeping bag of up to 4 or 5 lbs. Personally, I don’t think you can carry that much weight. The further you go, the heavier everything seems to be. Hoisting a 4-lbs sleeping bag could be a mundane task after a while.

I think the limit weight should be under 3 lbs. Recently, many manufacturers, understanding the importance of having a light sleeping bag, are presenting alternatives such as quilt and hoodless bags, which offers much lighter options. I have already reviewed many light yet reasonably priced sleeping bags that even weight less than 2 lbs.

What temperature is a 3 season sleeping bag?

Experienced campers often opt for 3-season sleeping bags because of its versatility. A 3-season will give you adequate warmth even in unfavorable weather. So, what exactly the temperature rating of a 3-season sleeping bag?

Manufacturers don’t invent the temperature rating. They often test the bag individually and often based on a standard, such as EN, to give the final grade. If your bag is tested on this standard, it will be marked EN13537, and it usually provides detail rating such as extreme, lower limit and comfort temperature zones.

As for a 3-sleeping sleeping bag, it is essential that its temperature rating falls somewhere between +10 to +32°F. When buying a sleeping bag, don’t just count the temperature rating without knowing the actual temperature in the place you opt to go.

My advice is to choose a bag with roughly 5 to 10 degrees lower than the actual temperature to make sure that you won’t freeze when the weather suddenly changes. What’s more, take note of your metabolism and other outdoor gears such as tents or sleepwear as they can significantly affect your comfy night inside the sleeping bag.


Mummy sleeping bags are great companions for cold overnights. As you can see from my list of the Best Mummy Sleeping Bags For Camping & Backpacking, all of the chosen ones are lightweight and can be used as 3-season alternatives.

I hope this list and my answers to frequently asked questions would satisfy your needs and quest for the most proper sleeping gear.
