If you’re planning travel and want to throw in some adventures or camping packing a packable and ultralight sleeping bag is an an essential piece of gear.

Heck, maybe you just want to make sure you stay warm or don’t trust the hostels sheets!

I know I’ve certainly came across situations during my travels through 40+ countries that I wish I had a sleeping bag in my pack.

Given that modern sleeping bags are super lightweight and pack down to a small water bottle, they are far from a burden to find room for in your pack. So, let’s get to it and breakdown how to choose the right one.


Finding the Best Ultralight Sleeping Bag

Ultralight sleeping bags generally come in two types depending upon their insulation fill: natural down fill and synthetic fill. Both insulation materials can be utilized to produce an ultralight, yet warm sleeping bag. It mostly comes down to user preference, weight, performance when wet, and packability.

Down sleeping bags are constructed with natural down feather filling whereas synthetic insulation uses specially prepared material, mostly polyester as filling. There are benefits and drawbacks for each insulation type (see below for which fits your needs best).

Down sleeping bags are suitable for very cold but dry usage. They are warmer than synthetic bags of the same weight, but also have a higher price. Down sleeping bags do not perform very well when they are wet.

On the other hand, synthetic sleeping bags are very versatile and can be used over a wide range of temperature, although not as suitable for super extreme cold. Another benefit is that they perform well even when they are wet. They have a relatively lower price tag as compared to down filled ones as well.

Ultralight Sleeping Bag Uses

For travelers, an ultralight sleeping bag is a great thing to have when headed on adventure and outdoor trips. It can come in very handy especially if you plan for camping or even staying in hostels or hotels.

It can keep you safe from the cold and provide you the comfort you need anywhere you want, for which general camping equipment or hotels may not suit your cleanliness or warmth needs.

Moreover, if you go for hiking or camping, a high quality lightweight sleeping bag can give you that extra bit of freedom. You can plan to stay wherever you like without the fear of not having a comfortable sleep.

A well-designed and dependable sleeping bag will keep you warm and comfortable, ensuring that you’re that you stay fresh and fit during your tour and enjoy your tour the way you like.

Some important factors to consider when choosing an ultralight sleeping bag are mentioned below.

Choosing the Right Ultralight Sleeping Bag


The lighter the bag, obviously the easier it is to carry and typically the smaller it packs. Many ultralight sleeping bags weigh under 2.0 pounds, with some even coming in at under 1.0 pound.

Hence, it is recommend to choose a lighter bag as it will be less of a burden carrying it day-after-day on travel. Plus you’ll be able to use it for climbing and hiking without being bogged down.

However, they may be a bit expensive and you may have to trade-off between weight and price.


The material and fill is one of the most important aspects when choosing a sleeping bag. It determines the durability of the bag, the warmth it provides and the overall performance in various conditions. Depending on how you plan to use your ultralight sleeping bag, one insulation type may fit you better.

If you want the lightest possible bag, your best bet is to go with a high-quality down. If you want a ultralight sleeping bag that can keep you warm when you find yourself in wet conditions, a synthetic insulation may suit you better.


A good quality zipper and design can make the bag easier to use (not allowing material to get caught/jammed in the zipper). Also consider a right vs. left side zipper depending on which side you prefer to sleep on.

Two way zippers are an even better option while choosing a sleeping bag since you’ll be able to open the bottom on hot nights to better regulate your body temperature. This can make a bag rated for colder conditions much more usable on warmer outings as well.


The length depends on your height or possibly what you’re comfortable with. It is recommended to buy a bag that is neither too long nor too short for your body, but if you have to decide having one that is slightly long is better than being cramped in your bag.


Having a bag that is wide enough to allow you to turn-over and switch sides can make a much more peaceful night’s rest. If you roll over a lot in your sleep you’ll want to make sure the bag you choose allows enough ‘wiggle’ room and mobility is a must.


While buying almost anything for travel, always looks for portability. The better the packability, the easier to carry along. Many ultralight sleeping bags pack down to a small ball that you can easily find room for in your bag.


The main purpose of the sleeping bag is to provide you a good sleep. Different bags vary in their comfort features. It highly recommended not to lose out on this feature—make sure you’re comfortable in your sleeping bag.

Water Resistance

A lot of ultralight sleeping bags come with a water resistant coating, such as DWR. This can be great for keeping your bag dry against small spills or light encounters with water. However, don’t count on it keeping your bag dry in extended rain or wet conditions.

Also, a DWR coating on a sleeping bag (or any gear for that matter) will wear off over time. You can always restore the DWR finish with an easy at home DWR wash or spray.


This one is an extra feature. A few pockets in your bag can be very useful. They can be used to keep important gear stuff near you like mobile phones, watches etc.

Keeping in mind the above features, below are a few possible pros and cons of a sleeping bag.

Price Range

The bad news is that with most travel and outdoor gear, the lighter weight, the more expensive. This is generally true with sleeping bag models as well, but it doesn’t mean that you have to break the bank to get yourself a high-quality bag.

You can expect to spend anywhere from around $200 a entry-level bag to $500+ on the best ultralight sleeping bag models. With both down and synthetic insulation, the lighter the bag, the more you’ll pay.
