How to choose the best budget sleeping bag for backpacking?


Sleeping bags are one of the heaviest items in your backpack among tents, backpacks, sleeping pads, etc.

A heavy backpack would be my last choice. I might save some energy instead. Don’t you agree?

So it’s a good place to cut pack weight.

Some of the highest performing bags use lightweight ultra thin shell fabrics in addition to a competitive down fill power. The bulkier bags are mostly made of Synthetics or of very low down fill power.

Ideally, choose a down insulated sleeping bag that weighs somewhere between 1-2 lbs.

Temperature Ratings and Warmth

All sleeping bags come with a temperature rating that tell you how much of cold your sleeping bag would sustain. But sadly, most of the specifications are not true when used outdoors.

The bags that specify a lower limit tell you that you can survive the cold up to that, and not that you would still feel warm at that temperature.

That means you’ll be in for a sleepless cold night.

So, what’s the trick?

Choose a bag that is warmer than it is specified to be. ( It will always be so)

For warm nights, it is recommended to go for a bag with 10-15 degrees Fahrenheit and 25-30 degrees for colder needs.

Quick Tip: You can always make any sleeping bag warmer than it is, by adding layers.

Down Fill power / Compressibility

Down fill power means the amount of insulation in the bag, which tells you how much your sleeping bag would weigh, and how much it can be compressed.

Sleeping bags with a higher down fill power weigh less and get compressed more easily as compared to low down fill power.

Down insulation is the clear winner here. But choosing a budget sleeping bag with a down fill can be challenging. Most of the bags that we have chosen are a good mix of weight and price.  

Fill material – why choose Down insulation over Synthetics?

Here’s the catch:

The insulation of your bag translates to you getting a warm & pleasant sleep. It’s as simple as that. So, how do you decide between the two?

My choice – hands down, Down 😀

It has an amazing weight-to-warmth ratio, it’s compressible ( if you own a down jacket, you can vouch for this ), and durable. If you are looking at a good quality sleeping bag that would last for more than 10 years, invest in a Down sleeping bag.

Synthetic has advantages in wet conditions, since it tends to dry faster, and also is not allergenic and priced lower than Down insulated sleeping bags. However, it has serious downsides to it like the weight of it.

Fit – Quilts or Mummy bags?

Mummy Bags

Mummy Bags, true to its name, encloses you like a mummy, with very little space left for anything else inside it.

It can feel a little packed because of the spacing inside the bag, but personally I would definitely go for this one since I enjoy cozy settings. Even at my home, I like sleeping like that in my bedsheets!

They come off as two types – one with hoods and the other without hoods. They are narrower the the bottom and wider at the top thus enveloping you completely.

It’s a good choice to go for Mummy bags when the temperature is below freezing.


If you are that kind of a person who likes to move around a bit freely while sleeping, Quilts are the ones you should be going for. They don’t come with hoods so you will have to purchase one separately.

Quilts are popular because of the weight-to-warmth ratio they provide, owing it to the sleeping pads that are attached to it.

It’s a good choice to go for Quilts when the temperature is above freezing.

Durable Water Repellents

Bags that come with a durable water repellent ( DWR ) coating, come useful during wet conditions. They add an extra layer of protection to the sleeping bag that beads up the water outside it by preventing it from soaking in.

The DWR coating is usually done on the bag’s shell fabric. It does not make the sleeping bag any waterproof but it’s a good add-on to have.

Point to note, the DWR coating needs to be reapplied once in a while since it tends to wear off with time.
