Choosing The Best Budget Sleeping Bag: A Buying Guide

With all the different budget sleeping bags out there, it can be difficult to decide which one is right for you. Here are a few things you’ll want to consider:

  • Temperature rating
  • Comfort rating
  • Water resistance

Ask yourself where you plan on using your sleeping bag. What kind of weather are you likely to encounter?

Every sleeping bag has a temperature rating. This rating indicates the lowest temperature at which they can be used. So, you’ll definitely want to pay attention to that.

Many sleeping bags will also have a comfort rating. This indicates the lowest temperature at which you should be able to sleep comfortably if you’re someone who’s sensitive to the cold.

There’s nothing worse than a wet sleeping bag. It’s crucial that the one you end up going for is made of materials that are breathable while still providing some degree of water resistance.

Keep reading to find out everything you need to know about all these factors to make sure you pick out a sleeping bag that’s going to fulfill your needs.

Temperature Rating

Let me start by telling you right off the bat, the temperature ratings on sleeping bags can be deceiving. They should never be taken at face value. Instead, use them as more of a general guideline and take the following into consideration when looking at your options.

We all sleep differently. Some people are more sensitive to the cold and need a lot of heat to stay warm. Others are most comfortable sleeping in cooler conditions. This means that what’s warm enough for one person isn’t necessarily going to be warm enough for everyone.

“So,” you ask, “how can I know if a sleeping bag is going to be warm enough for me?” Well, what I would recommend is to think of the manufacturer’s temperature rating as applicable to those who are less sensitive to the cold. If you’re a warm sleeper, you should be right going by the official rating.

If you’re anything like me though, going by this rating could leave you chattering your teeth. Anyone who’s spent a night (or worse, several nights) freezing their cheeks off in a tent can tell you, it isn’t much fun. So, if you are a cold sleeper it’s a good idea to add 10-15 degrees to the manufacturer’s temperature rating.

For instance, if a sleeping bag’s temperature rating is 30 degrees Fahrenheit, I personally wouldn’t take it on a camping trip if I was anticipating weather under 45 degrees. Again, that doesn’t mean someone else couldn’t use it in 30 degree weather and be perfectly comfortable.

Comfort Rating

In some cases, the manufacturers will have taken this discrepancy into account. In turn, you’ll often see a comfort rating in addition to the temperature rating.

Here’s the difference. The temperature rating indicates the lowest temperature the sleeping bag is suitable for. The comfort rating indicates the lowest temperature at which a cold sleeper should feel comfortable.

Still, I wouldn’t take this at face value either. Aside from whether you’re a cold or warm sleeper, there are a number of other factors that can influence how warm you are in a sleeping bag.

For instance, having additional gear such as a sleeping bag liner or a sleeping pad is going to make a huge difference when you’re camping in cold weather. The clothes you wear while sleeping also play an important role. Believe it or not, even the food you consume is going to have an impact on how warm you are during the night.

It’s also interesting to note that women are on average colder sleepers than men. Because of this, the comfort rating on a men’s sleeping bag will often be equivalent to the temperature rating on the women’s version of the same product.

Water Resistance

When it comes to sleeping bags, it’s all about finding the best possible balance between water resistance and breathability.

Because sleeping bags have to be breathable, they’re only water resistant to a certain degree. Still, some sleeping bags provide better protection from moisture than others.

This will depend largely on the material used to make the outer shell of the sleeping bag.

Polyester, nylon and taffeta are all great examples of water resistant materials that aren’t expensive. Ripstop is a class above these materials in terms of durability.

The best materials are highly breathable and water resistant, such as Gore’s DryLoft. However, materials such as these come at a far greater price.

Sleeping bags with a durable water repellent (DWR) finish provide better protection from moisture. This will also make them highly resistant to stains and tearing.

Some sleeping bags, such as the Kelty Cosmic and the Marmot Trestles 30, feature insulation like CirroLoft and SpiraFil, which actually stay warm even when soaking wet.

Our Verdict

That’s pretty much all you need to know about picking out the perfect sleeping bag. Hopefully you now have a better idea of the kind of things you need to look out for.

Which one would I go for? It would have to be the Kelty Cosmic. In my eyes, it’s clearly a cut above the rest. It’s warm, ultralight and eco-friendly. No matter what your needs may be, this sleeping bag has got you covered.

It might not be the absolute cheapest, but in this case for just a little bit extra you really do get a whole lot more.
