Ultralight Sleeping Bag under 100 Buying Guide – Factors to Consider

Want the best ultralight sleeping bag under 100? Then learn what to look for before buying.

Nothing will help you more than having a decent understanding of what an ultralight sleeping bag can offer for such a price. This will make it easy to pick the perfect model, whether you’re looking for comfort, protection, or portability (or all at once).

Below, we’ll explain all the key factors to think about and how each one affects your experience. Take a look:

Weight & Storage

An ultralight sleeping bag needs to be easy to move around. Sure enough, the first thing that comes into play is the weight.

Here, we recommend going for bags that don’t weigh more than 4 pounds. Anything over that range is not an ultra-light sleeping bag anymore. Yet, you can make exceptions if the sleeping bag comes with an extra filling or at a larger-than-individual size.

Once you have the weight figured out, consider how you want to bring the bag around. We recommend compression bags with built-in cords and straps for extra portability. If you can compress the bag into a small sack, then that will make it a piece of cake to bring anywhere you go.

Temperature Rating & Seasons

Now you can consider the insulation level of the sleeping bag. Here, we recommend considering the temperature rating and the season it’s made for. Below we explain this deeply:


These bags are for temperatures between 30-degrees Fahrenheit and higher. You won’t get much cold protection for these, so we don’t recommend them is you expect temperatures to fall below 30 degrees at night. They can be a nightmare to sleep on.


If you prefer camping in fall and spring, then a three-season sleeping bag will be your best bet. They can handle temperatures as low as 20-degrees Fahrenheit. Some of them may come with extra ventilation ports and similar features so you can use them in hotter places at 30 degrees or higher.


In case you’re camping in a cold place, then go for a winter sleeping bag. These are usually thicker and heavy, so you won’t find these in the article. Yet, these can be perfect if you want to camp in places that go below 20-degrees Fahrenheit.

Insulation Type

Have a better idea of how the seasons and temperature ratings work? Then you should now learn how the insulation on sleeping bags work:


The most popular among ultralight sleeping bags is a synthetic material. This insulation usually refers to cotton or polyester fiberfill. It can get pretty warm and ensures decent insulation at night. What’s even better, synthetic is pretty affordable. Sadly, it makes bulky and less durable sleeping bags.


If you want to protect yourself entirely from the cold, then down feather insulation if your way to go. It is usually lighter and less bulky than synthetic material, but way more expensive. Luckily, down compresses really well and tends to be super comfy nonetheless. 

Size & Shape

Nothing will affect the weight and portability of the bag more than the size and its shape. However, the critical thing to consider is whether it fits your body and meets your needs.

Here’s more about how the size changes depending on the shape:


This is the typical type of sleeping bag, perfect for one person. Mummy models are thinner and shorter, so they are compact. You can find mummy sleeping bags going from 60 to 80 inches in length and between 30 and 40 inches in width.  These bags offer maximum portability.


Want to sleep with a partner in the same bag? Then you need a rectangular model. These can reach up to 100 inches in width, making them super spacious. These tend to be less protective but ultra-comfortable. Some models can be light and easy to pack, but most of them aren’t.


These are a combination of mummy and rectangular sleeping bags. They can reach 50 inches in width and 85 inches in length. The focus is to be decently protective while being super spacious and comfy. They are usually heavy and awkward to pack. 

Extra Features

 If you want to enjoy the sleeping bag to the max, then at least one of these features will help you:

Hood& Pillow

Don’t let your head unsupported or uncovered at night. Get a sleeping bag with a hood or pillow pocket so you can sleep more comfortably.

Quality Zipper

A stuck or broken zipper is never useful. Be sure the sleeping bag you’re choosing comes with a smooth, reversible, and unbreakable zipper.

Comfortable Lining

Want to sleep like a baby on the sleeping bag? Then choose soft linings like flannel that make it a pleasure to get inside.

Waterproof Exterior

When it starts raining, humidity arises. You don’t want that inside your bag, so pick a material that keeps it all out, like polyester.

Frequently Asked Questions (FAQs)

If that’s the case, then you may find the answer to your doubts in this section:
