If you’re going camping, backpacking, or other overnight adventures, a sleeping bag is necessary. But many of them are expensive. As a result, I’ve put together this guide to help you identify the best ultralight sleeping bag under 100 in 2021. So, let’s get to it!

Best Ultralight Sleeping Bag Under $100

TETON Sports Celsius XXL

This particular sleeping bag is absolutely awesome. It is a bag for people who have tall and big frames. I’ve used it before myself, and I can tell you that you won’t be able to guess it unless someone tells you the price. The features are top notch, and it brings comfortability to every adventure. 

To begin with, the material of the sleeping bag is 100% polyester. It has a double layer construction, soft lining, and draft tubes that will have you sleeping like a baby all night long. I know I did!

But that’s not all this compact sleeping bag is good for. It also can keep you warm in low temperatures. This means that even if the temperature is 0°F, this particular sleeping bag will be able to keep you warm. Other features I found interesting are the interior storage pocket and adjustable hood.

Pros

  • The soft lining makes it feel nice against the skin
  • The sleeping bag is very comfortable
  • It is very big
  • It is also warm

Cons

  • It is heavy

Takeaway

People of different sizes can use this sleeping bag because of its ability to adjust.

When it comes to durability, this sleeping bag is one of the best. There’s also a coating shell, so the sleeping bag is waterproof and soft. The insulation is also great. This means that you can use it when the weather is cold. Of course, you can’t use it in freezing weather. The temperature it’s conducive for is between 35-40° F. Unlike the TETON Sports Celsius XXL, this sleeping bag is light and will be very easy to carry on camping trips.

Marmot Trestles 30 Mummy Sleeping Bag

This mummy-style sleeping bag is one of the best on the market. The outer and inner liner of this sleeping bag is constructed with 70D 100% polyester. The insulation and lightweight nature of this bag make it the best for camping and other outdoor adventures.

But that’s not all! This sleeping bag also comes with its own unique features. One of them is the “anatomically shaped foot-box” at the bottom. This feature alone makes the already amazing sleeping bag the most amazing sleeping bag as far as I’m concerned. 

In order to trap in heat, wave formation is used in the blanket construction. The sleeping bag even comes with dual zippers on the side to create extra openings and enhance movement.

Pros

  • The sleeping bag is incredibly comfortable
  • It is very light
  • The materials are durable
  • It can be used at 30°F temperature

This sleeping bag is both affordable and impressive. It comes in a mummy style, and it is capable of fitting anyone who is 6 ft 2 and below. The insulation is top-notch. It can be used well in low temperatures. The hood closes with a drawstring.

But that’s not all! This sleeping bag comes with a foot box that’s insulated, and to prevent any snagging while you’re zipping your sleeping bag, the ZipPlow system was used in the bag’s construction. Polyester was used to make the sleeping bag. Both the filling and the liner are polyester. This means you can toss the sleeping bag in the washing machine without stress.

The only downside of this sleeping bag is that it is 5 pounds, and that’s not light enough for many outdoor adventures.

Pros

  • The sleeping bag is very spacious
  • It can be washed in a machine
  • It is water resistant

Cons

  • It is heavy
  • Although the temperature rating is 0° F, it can’t be used in that weather

Takeaway

Abco Tech Sleeping Bag

If you’re looking for an affordable sleeping bag on a tight budget, then the Abco Tech Sleeping Bag is your answer. This awesome sleeping bag comes with a 20° F temperature rating. The materials used in its construction make it weather-resistant. It is also waterproof. 

The insulation system is also an effect of its polyester construction. 210T polyester is used to create its outer shell and the lining is made from 100% polyester.

TETON Sports Tracker Mummy Sleeping Bag

For a bag that’s under $100, the TETON Sports Tracker does exceptionally well on camping trips and other outdoor adventures. The bag comes in the classic mummy style, and it leaves a lot of room for whoever is using it to get very comfortable. It also does well in cold weather. The temperature rating is 15° F to 20° F. 

Surprisingly, despite the roomy nature of the sleeping bag, it can also be easily compressed into the compression bag that comes with it. 

What does this mean for you?

It means it’s easy to carry for backpacking trips. This makes it one of the smallest packing sleeping bags in this guide. Also, simply because the bag is easy to compress doesn’t mean it has some additional weight. You will hardly feel this bag’s weight while carrying it in a backpack.

The construction of this bag is amazing. The hood is designed in a way that makes it possible for you to adjust it to your preference. A Velcro strap also covers the zipper, so you won’t get harmed or injured by it while you’re using the bag.

It comes with a pillowcase and a storage pocket on the inside for you to store your valuables. The temperature rating for this bag is 50°F.

However, that does not mean its features are not top-notch.  If you enjoy going on outdoor adventures with your partner, it’s roomy enough to occupy both of you together. It’s also one of the best bags for couples out there.

However, there are times when you don’t want to sleep with your partner, and that’s where the special feature of this amazing sleeping bag comes to play. You can split it.

Things You Need to Consider When Buying a Sleeping Bag

In this guide, I’ve tried to write about as many great sleeping bags under $100 as I could, but it’s possible that you may want to buy a sleeping bag that’s not on this list. That’s why you have to watch out for a list of things when making your own purchase has been put together.

Type

There are generally two types of sleeping bags you’ll find on the market. Yes, I’m talking about the rectangular sleeping bags and the mummy-style bag. Of course, there are hybrid types that combine the features and benefits of both types of sleeping bags, but they’re not very common. 

The mummy-style is a snug fitting sleeping bag that provides maximum warmth but is not big on comfort most of the time. However, they’re still light weight.

On the other hand, the rectangular sleeping bag is more common. Why may you ask? The answer is simple! It’s because it’s usually cheaper. However, it may be heavier than the mummy-style sleeping bag depending on the manufacturer. 

Temperature Rating

This matters a lot when you’re choosing a bag. Remember that your tolerance may be different from others. You want to pick bags around 20 degrees for cold weather and something around 40-50 degrees for summer, so you won’t feel the heat too much. You can also pick something in between and wear extra clothes when it gets too cold, increasing the heat inside the sleeping bag. 

Weight

With sleeping bags, weight equals portability, and for a backpacker, that’s everything. There won’t be space to carry anything else if your sleeping bag takes most of the space. That’s why you have to ensure that your bag is lightweight and also capable of being compressed. 

However, if you’re driving a car to your campground, you can opt for heavier bags.

Features of a Bag to Watch Out for

Stuff Sack

Many sleeping bags come with stuff sacks to make them compact and easy to carry around. Stuff sacks can either have compressors or not. Both types are great as long as the sack is not just for decoration and your sleeping bag can actually fit into it. You should also make sure that the stuff sack can fit into your backpack or car. If it can’t fit, that defeats the purpose.

Hood

This is typically in a mummy-style sleeping bag. It has several benefits. It can ensure that your head is warm throughout the night, and it can also help you keep your pillow in place. If your sleeping bag is in the mummy-style, ensure it has a hood.

Insulation

Insulation in a sleeping bag is categorized into two, down insulation and synthetic insulation. A lot of people believe that out of the two, down insulation is better. But bags with down insulation are usually more expensive. They also don’t perform as well as bags with synthetic insulation in better conditions. 

While the insulation in down insulation is gotten from feathers and furs, synthetic insulation uses synthetic materials like polyester. It is also the better option to use in wet conditions.

Price Considerations

The truth is there are a lot of sleeping bags that work really well in the market. Even though your goal is to buy a bag under $100, you don’t have to buy a bag that’s very close to that price. You just have to do enough research and know what to look for.

Good Zipper

A good zipper is important in a sleeping bag. You want to be able to zip up from inside without the zipper getting stuck. Zippers that get stuck can be really frustrating when you’re trying to lie down and get some rest. That’s why you should always go for high quality zippers.

Another feature you should pay attention to when it comes to zippers is Velcro covers to prevent you from getting scratched or injured by the zippers while you sleep.

FAQs

Which type of sleeping bag is the best?

That would be the mummy-style sleeping bag. It has a snug fit and is perfect for all seasons. Many seasoned campers would rather go for them than the rectangular sleeping bag. However, the rectangular sleeping bag is also great if you like comfort above all else.

Are sleeping bags expensive?

Yes, they are. If you’re getting ready for an outdoor adventure, they’re usually the most expensive of your gear. That’s why I have compiled a list of the best sleeping bags you can possibly get under $100. 

Do I need a warm sleeping bag?

Yes, you do, but this depends on the weather condition. For example, if you’re camping in winter, you’ll need a sleeping bag that can handle 20 degrees Fahrenheit or below at least, and if you’re camping in summer, you might want to go for sleeping bags that have a resistance of 40 degrees Fahrenheit or above.

Conclusion

Finally, I’m here, and I must say this guide was enjoyable to write. I’ve written about sleeping bags from different price ranges, and it’s time to name the best ultralight sleeping bag under 100 in 2021, but I just can’t. All of the bags in this guide are great.
