Its ThermaPro insulation is top-notch. It is tailored to not only retain body heat while you are inside the bag but also to remain compressible enough to make packable for easy transportation.

Because this bag from TETON Sports is rated at 20 degrees F and higher, we did not find it as one of the best sleeping bags for winter.

  • Brushed polyester cover and tricot fiber blend liner provide softness and breathability
  • ZipPlow system plows away fabric to prevent snagging during zipping
  • Roll Control design and Quick Cord system for easy rolling and securing

There is no doubt that Coleman is one of the top manufacturers of outdoor products. It surprised us that this company can be among the ones that manufacture budget backpack sleeping bags. Because of its record of accomplishment, you would expect Coleman only to produce premium sleeping bags.

Just because it is freezing outside while on a camping or hiking trip does not mean that you need to grapple with the cold, do you know that this Coleman sleeping bag is ideal for temps that drop even to 0 degrees F? Oh, yes, you heard us right! With this bag, it is possible to remain warm from head to toe, all thanks to its patented insulation coupled with quilted construction that gets rid of cold spots inside your sleeping bag.

It comes with a hood that adjusts with a drawstring that tightens around your head to perfectly lock in your body heat. Also, there is a box-shaped foot to give you more room to move during the night. You can move your toes comfortably regardless of the sleeping position.

The outer shell of this sleeping bag is polyester ripstop that is exceptional at resisting tears for a more durable bag. For additional warmth, a full-length Thermolock draft tube is available to guarantee the retaining of body heat as well as keeping out of outside cold temperatures.

The bag’s zipper is two-way without a snag design to protect the fabric from being caught in the teeth.

While we love it as one of the best backpacking sleeping bags below $100 when it comes to warmth and construction, the bag is pretty heavy (5 lbs). Due to this reason, we don’t think it is an excellent fit for people who are doing long treks deep in the woods.

  • Drawstring Hood and Draft Tube for Additional Protection Against the Elements
  • Double-Layer Offset Quilt Construction 30 degree rated
  • Compression Stuff Sack

Although the Suisse Sport sleeping bag is among the most affordable sleeping bags in the market, it brings with it exceptional features present in the expensive brands. The Adventurer is lightweight, making it effortless to carry around when out for a hike or camping.

Its material is polyester ripstop. It is water-resistant and durable. One of the best attributes of this bag’s fabric is the fact that it dries pretty fast should get it damp.

It has a double layer construction that adds comfort and warmth on the cooler nights. The bag is quilted to mitigate any chance of cold spots from getting inside. It comes in a mummy-shaped design that consists of a contoured drawstring hood coupled with a collar to ensure your shoulder and throat are protected from the cold air as you rest.

Its temperature rating means that it is one of those sleeping bags that are a must-have for the summer. We also loved it because it is designed to fit various types of people, including the left and right-handed folks. Because of this, whether you are right or left-handed, you will certainly have an easy time zipping yourself.

To block out cold air, a draft tube that runs over the zipper is available. Just like many others on our primer, it comes with a pocket to store your valuables. On top of that, there is a compression sack for easy carrying and fast storage.

The only downside that we discovered with this inexpensive sleeping bag has to do with the fact that it only fits people who are below 6’ and with a 19’’ width. If you are a larger person, this bag might be somewhat tight on the shoulders.

Buying Guide: Things To Consider

As we mentioned before, there is a wide range of sleeping bags to choose from. For this reason, you need to have well-thought-out criteria to act your guide. Here are the most important factors to consider when shopping for the best budget backpacking sleeping bag:

Insulation Type

The kind of insulation used is what differentiates sleeping bags. Here are the most common insulation types:

  • Synthetic/down combinations – This type of insulation features a combination of synthetic and down materials to provide you with the benefits of each of the mentioned materials.
  • Synthetic insulation – Polyester is the most common material utilized for synthetic insulation. In addition to drying quickly, it insulates even when wet. The other advantage is that it is non-allergenic and affordable.
  • Water-resistant down – The down insulation is treated with a quality water-resistant application that prevents it from becoming soggy lump if at all, it gets wet. Sometimes, it is also known as hydrophobic down.
  • Duck down – While duck down insulation boasts similar qualities as goose down, it does not achieve the same a fill rating. Nonetheless, it is highly popular due to its affordability.
  • Goose down – The goose down insulation is not only lightweight but also brings with it the best fill ratings. While it is the best insulator and easy to compress, on the flip side, it is the most expensive option.

Sleeping Bag Weight

Two main factors affect the weight of a sleeping bag – its shape and insulation. The more efficient insulations such as the high-fill-power downs and advanced synthetics deliver greater warmth at less weight compared to the less efficient fills. Since a sleeping bag needs more insulation to be warmer, you need to compare bags with a similar temp rating when equating weights.

  • Insulation fill weight – What matters the most when carrying a sleeping bag in your pack is the overall bag weight. Insulation fill weight only reveals a bag’s insulation weight. Some people use it as a rough indicator of bag warmth. They are reasoning that having more fill inside the bag makes it warmer. However, the most reliable indicator of a bag’s warmth is its temperature rating spec.
  • Sleeping bag shape – By now, you know that sleeping bags maintain warmth by retaining the heat emitted by the body. What does this mean? It simply means that a small space tends to warm more efficiently compared to a bigger one. Additionally, a bag with a snug fit and sleek shape is lighter compared to one that is roomy. Find out more about sleeping bag shapes below.

Lining and Shell

Most backpacking sleeping bags feature an outer shell that is made of polyester or nylon. Some have a breathable and waterproof shell. Others feature a shell treated with water-repellant. You need to have a feel of the lining to establish if it feels soft. A soft feeling means you shall sleep comfortably.


Size is mostly about a sleeping bag’s length. When searching for the best inexpensive backpack sleeping bag, you need to ensure that it is the right length in terms of your height. Most bags come in either long or medium sizes. For tall users, you will be glad to know that there are manufacturers that make extra-long ones. Similarly, some manufacturers focus on petite or short sleeping bags to cater for the short folks.

Sleeping Bag Shapes 

It is essential to understand the different backpacking sleeping bag shapes. Each shape or cut is tailored to appeal to different types of users. Here are the three most common ones:

  • Rectangular

Without any taper through their legs, rectangular bags are not thermally efficient. They are an excellent choice for basement sleepovers and backyard campouts.

  • Semi-Rectangular

Semi-rectangular backpacking sleeping bags, a happy medium between rectangular and mummy shapes, are an excellent choice for any camper that cannot cope with a mummy’s bag confinement but still needs more warmth than that of a rectangular bag. Although they are heavier and bulkier compared to mummies, they provide a more thrashing room. 

  • Mummy

Mummy sleeping bags are cut through the feet and legs to give them maximum thermal efficiency. Remember that the primary goal of a sleeping bag is to contain your body heat. When it has a smaller interior space, it is more efficient at meeting this objective. While many mummies boast plenty of room via the torso and shoulders, broader campers and restless sleepers might be more comfortable with an alternative cut.

Another significant benefit of a mummy bag is that it utilizes less insulation and materials. Additionally, they are smaller to pack and lighter-weight.


Are you a woman? If yes, you need to settle for sleeping bags that are tailored for women. Such bags are designed based on the outline of a woman’s body to provide more comfort.

Type of Sleeping Bag

Backpacking sleeping bags are usually grouped based on the seasons you would use them and their temperature rating.

They fall into three major categories (they are categorized based on their temperature rating) – winter, three-season, and summer.

  • Summer (Two-Season)

Summer backpacking sleeping bags are ideal for temps of 30 degrees F and higher. In addition to packing down tiny, they are also lightweight. Often, summer bags feature full-length zippers that allow users to zip them almost entirely open for ventilation whenever the night is steamy. Most of these bags are just simple sacks without many whistles and bells. There is no need for a draft collar or hood on the hot July nights.

  • Winter (Four-Season)

Winter sleeping bags are puffy cocoons. They are excellent for temps of 20 degrees F and below. They boast all the features of a 3-season bag but with more insulation. Since they are bulky to pack, you need to have a compression stuff sack.

  • Three-Season

The three-season sleeping bags are perfect for temps of 20 degrees F and above. These types of bags are suited for fall and spring trips. They are also great for summers in the mountains when temperatures can dip below freezing particularly at night. The best three-season bags bring with them extra features to handle colder temperatures. Some of these features include zipper draft tubes, draft collars, and cinch-able hoods.

Zipper Side

Zipper side varies based on the bag you settle for. Unless you prefer a certain side, which you want your zipper bag to be, normally, this factor should not be a major issue. However, the size of a zipper will matter if you intend to mate two sleeping bags together. For you to do this, ensure one of the bags has a zipper on its right side while the one should have it on its left side. In such a scenario, the zippers must be of the same size. If they are not, they will not work together. Additionally, the zippers need to be of similar size.

How To Wash Your Backpack Sleeping Bag

To ensure your investment remains lofting high, here are some tips for washing your sleeping bag:

Step #1: Pass through the label

If you cannot find much information on the label, check on the company’s website. If the cleaning directions contradict any of the tips we have offered, follow those from the manufacturer.

Step #2: Batten down the hatches

Once you have passed through the directions, close all fasteners and zippers. After that, turn your bag inside out in a way that the body oils in the interior wash off.

Step #3: Always use the right soap

When cleaning, you need to use a cleaning product that will not strip any essential oils from your bag’s feathers.

Step #4: Wash 

You can use a front-loader or hand-wash in a tub as the agitator inside a top-loader can tear baffles. It is prudent to choose a gentle cycle with some cold water. Once you have run a complete cycle, rinse once or twice to get rid of the soap.

Step #5: Remove carefully

Finally, yet importantly, it is time to remove your sleeping bag. You need to do it carefully. The right way to remove it is by supporting it from underneath to prevent the waterlogged insulation from ripping the stitches out. Hang your bag lengthwise on a laundry line. Leave it to dry until it becomes light meaning the water weight will be gone.

Step #6: Dry

Once your bag becomes damp, place it inside a commercial dryer. Dry it on low heat as you frequently check it. After every 30 minutes, remove down the bags to de-clump the feathers. Leave it unstuffed for a couple of days. When you store it, ensure you utilize a huge pillowcase or cotton sack, not the small nylon stuff sack that you use while you are on a trip.

How To Size Your Sleeping Bag Before Buying

Yours is a sleeping bag and not shrink-wrap. Use these steps to make sure it fits perfectly:

Step #1: Always try before you purchase

It is prudent to crawl into as many sleeping bags as possible. Wear appropriate layers to have an idea of the way every type and brand fit.

Step #2: Integrate the sleeping pad

Does your sleeping bag have sleeping pad straps or sleeves? If it does, rig it that into the store as a pad reduces its interior volume thus affecting its fit.

Step #3: Check the closures

In this step, you need to zip your bag up, down, and then up again. Once you do that and the zipper snags, it will do the same in the field. What to do? Cinch the draft collar and hood down. Look for a comfortable fit, snug seal around the head as well as no scratchy Velcro that rubs against your check. You also need to check the ease of exit.

Step #4: Roll around

Are you a cold-weather camper or cold sleeper? If yes, then you should choose a more snug fit. For the side sleepers and thrashers, ensure you can comfortably rotate your body.
