Buyer's Guide to Mummy Sleeping Bags

Comfort

Mummy sleeping bags are more narrow in shape at the feet than rectangle sleeping bags. They are also tighter around the body, this means there is less space around you.

This style of a sleeping bag is intentional and means that there is less space surrounding your body. Therefore less space for your body to try and warm up, meaning you'll use less energy and stay warmer for a long period of time.

Another advantage to mummy sleeping bags is that they are less bulky than traditionally shaped bags but still allow you to have your shoulder laying flat.

Ensuring you have a hood that fits is also really important as this will help retain heat and keep you comfortable. 


Function

Before purchasing a sleeping bag make sure you give some thought to what the function and purpose of it will be as this can influence what type of sleeping bags will be suitable for you.

  • Casual Camper - Opt for something bigger as this will generally be more comfortable. Budget wise this is the best bet when purchasing for a family. It will also provide the most comfortable night so a win all round!
  • Backpacking - Weight will be a factor as you won't want something too heavy to carry. Anything which can easily be compressed is a good option. Look for sleeping bags with a good warmth to weight ratio and you won't go wrong!
  • Mountaineering and Extreme Camping Trips - If the temperature is going to be a concern then consider a temperature rating of at least -20 degrees. Should you be planning on seriously going into the mountain, then aim for a -40 degree sleeping bag as this will provide the best comfort and safety.

Warmth

There are many choices when it comes to insulation so let's dive straight in:

Down fill - These sleeping bags are great for people who want to do alpine adventures or several days hiking in cold conditions.

Why?

Down insulation is going to keep you warm, without weighing you down during the day - generally known as the best warmth to weight sleeping bag out there. The insulation properties mean that these sleeping bags tend to be very lightweight. Another thing worth keeping in mind if you are planning on hiking over several days is that down-filled sleeping bags can compress down, making it much easier to pop into a backpack.

Though often a little pricer than other types of insulation, if taken care of, you shouldn't need to seek out a replacement of upward of a decade.

Synthetic fill - For people looking to do a spot of camping or traveling across a variety of climates, synthetic insulation sleeping bags are for you.

Why?

If damp conditions are something you may potentially face, then keep in mind that synthetic type insulation is fairly wet weather friendly. The fibers do not get as affected by moisture, they also trap the warm air surrounding your body - this helps to keep you warm, even in damp situations.

This type of insulation is very easy to maintain and care for. Simply throw it in the washing machine when you get back home and it's all ready and clean to go on your next adventure.


Extra Features

Having a few extra features is almost always nice but which ones are actually necessary will depend on what type of adventures you are planning on taking!

Some mummy sleeping bags come with what is known as a stash pocket. What this does is give you somewhere safe to keep your valuable while you are sleeping.

Adventures who are seeking cool climates should look for a sleeping bag with draft tubes. Generally speaking, a zipper is a weak spot in your bag, meaning heat can escape from there as well as drafts coming in. A draft tube aims to minimize that by providing an extra bit of insulation which covers the length of the zip

Particularly good for mountaineers are sleeping bags with waterproof and breathable membranes. These will help you stay dry and keep you well insulated.

Zips can get caught on sleeping bags and, this can cause damage to the shell fabric, shortening the life span of the sleeping bag. To prevent this, look for snag-free zips. Larger teeth will decrease the chance of snagging. 


Budget

For people who are frequently use sleeping bags then spending a bit more on a high-quality mummy bag (names such a rei co-op or down hugger may spring to mind) is a great choice and will certainly benefit from the extra features.

Those who are more occasional should keep in mind that it may not be necessary to spend hundreds of dollars on a sleeping bag and will find one that will work well for them on the lower limit of their research. 


FAQS

1. What are mummy sleeping bags good for?

Designed to be lighter in weight than a rectangular sleeping bag, mummy bags are ideal for when the going gets tough. Although it is worth noting that they are also suitable for lighter trips too.

Mummy sleeping bags often have better temperature ratings than their rectangular counterparts. This is down to the style and shape of the bag to a large extent.

This will mean that mummy-style sleeping bags will get a person through colder, harsher conditions. Due to their light-weight, they are ideal for people wanting a bag to pop into their backpack and not add unnecessary weight or size.

Regardless of which style of the sleeping bag a person chooses, it is wise to pair it up with a sleeping pad and pad sleeve as this will add to the amount of warmth being kept in and also comfort.


2. What should I look for in a sleeping bag?

Always consider sleeping bags' temperature ratings and choose one that is at the lower limit than the temperature expected at your camping location. The temp rating will tell you what the lowest temperature is that the sleeping bag will keep you warm.

Make sure you look at the packed weight of the sleeping bag. If you are car or mountain camping then lightweight is best as bulk and extra size will weigh you down.

Fill power between 800 and 1000 is perfect for portability.

It is also worth looking at any additional features as depending on your function some will be more useful than others. A draft collar will help keep your neck free from drafts. If you're headed into seriously chilly conditions then an extra membrane is handy. Or perhaps functionality is important, then consider a sleeping bag that you can unzip to make a quilt.

Don't forget a sleeping pad and pad sleeve!


3. How do you sleep comfortably in a mummy bag?

Cascade Mountain Tech Mummy Sleeping Bag

The key to sleeping comfortably and getting a good night s sleep in a mummy sleeping bag or any sleeping bag is to dress properly and ideally use a sleeping pad underneath for extra comfort.


Remember a sleeping bag is basically a quilt with zippers. A mummy-style bag will help keep the warmth in and your feet toasty due to their shape which is better for heat retention and insulation than the rectangular shaped bags.


Generally, most mummy-style sleeping bags will be single sleeping however it is possible to get bags with a right and left-handed so that they can be zipped together for double sleeping.
