If you love backpacking, then you already know a sleeping bag is one of the most important items you need to pack with you. When buying a new sleeping bag, most people tend to look more at features that provide warmth. Undoubtedly, this makes sense since a warm sleeping bag will determine your sleep quality.

However, another essential feature is for the best sleeping bag to be lightweight. An ultra light sleeping bag is ideal for many backpackers who understand that a lighter load makes all the difference when hiking through anomalous terrain. Let’s delve further into how to choose an ultra light sleeping bag and what you should avoid.


Why Select an Ultra Light Sleeping Bag?

In the last few years, backpacking equipment has advanced significantly to provide backpackers with a more comfortable experience. One such piece of equipment is the ultra light sleeping bag.

As its name might give away, the most significant advantage of an ultra light sleeping bag is its lighter weight. A lightweight sleeping bag is perfect for climbers, who look to pack items with the lightest load possible. Also, it allows thru-hikers who hike long distances that don’t need to add extra stress on their bodies.

An ultra light sleeping bag is also lighter to carry, easier to pack, and takes less space in your backpack than regular sleeping bags. Like ultra light sleeping bags, backpacking quilts with little weight are also often preferred by people looking for extra comfort.

Of course, it should be noted that ultra light sleeping bags are not a perfect fit for everyone. While there might be better for certain situations, you might find them inconvenient in some circumstances. Besides weight, other essential characteristics that you should be looking for in a sleeping bag are durability, warmth, and comfort.


What to Look For in an Ultra Light Sleeping Bag

Before buying any backpacking equipment, pay close attention to a few things, when shopping for an ultra light sleeping bag.

Insulation

The type of insulation your sleeping bag has is a significant characteristic, especially for an ultra light sleeping bag. You have to be careful because many ultra-light sleeping bags use less insulation in order to reduce the overall weight of the sleeping bag. While this makes it easier to carry, don’t forget that the sleeping bag’s primary purpose is to keep you warm during the night.

There are two kinds of insulation: down and synthetic. Synthetic sleeping bag insulation is usually made from polyester but generally makes for heavier sleeping bags. Perhaps its most significant advantage is that synthetically insulated sleeping bags are ideal for in wet environments.

A sleeping bag with synthetic insulation can keep you warm when damp and takes less time to dry. They are also less expensive than sleeping bags made with down insulation.

Down insulation is often used for ultra light sleeping bags. They are considered the best of its kind, which is why it is generally more expensive than synthetic. Down insulation is durable but easy to compress and has little weight, making it a good ultralight bag option.

Often, to trim down the weight even further, these sleeping bags don’t include some standard features like a hood or a zipper.

Down insulation also has a form of measurement that determines the quality of the insulation and the fill power. Specifically, the fill power measures the thickness of the insulating matter, the loft, in an ounce of down. A higher number would indicate that the sleeping bag would generate additional warmth analogous to its weight.

A high-down fill power sleeping bag needs less material to generate warmth, which in turn makes it lightweight. Therefore, a warmer and lightweight sleeping bag would be more expensive. Alternately, a traditional sleeping bag with a lower fill power can still offer ultra comfort and extra warmth.

The fill power measurement numbers range between 500 and 900. No form of measurement for synthetic fills is equivalent to the fill power.

Weather-Proofing

Finally, weather-proof material is also something important to consider. Most backpackers know that things can get challenging once your sleeping bag gets wet. Therefore, most people try to avoid getting their backpacks completely wet in any way possible.

Many sleeping bags are water-proof; as mentioned earlier, synthetic sleeping bags continue to insulate while wet and dry up fast. However, some are only suitable for warmer environments, and if they get wet, it becomes challenging.

Therefore, purchase the best sleeping bag and general other equipment for camping, specifically for the conditions you expect to face. You should always be prepared for any weather changes. If you are going to a place with variable weather, then it is better to be ready for various weather conditions.


5 Mistakes You Should Avoid

1. Do Not Sacrifice Warmth Over Lighter Load

A lighter load can make a big difference for a climber or a hiker that knows how hard it can be on the body to carry a heavy backpack while hiking long distances. However, no matter how vital a lighter load is, you should be aware of what you might sacrifice for it.

A sleeping bag that is easier to pack and carry might not provide you with the warmth during a cold night. A good night’s rest is often considered necessary for people who go through long distances.

If you don’t get rest, you won’t have the energy to continue your trip the next day. For example, an ultra light sleeping bag might not be able to withstand colder temperatures, just like a 3-season sleeping bag.

Thankfully, many ultra light sleeping bags are made with high quality materials that provide strong insulation. However, people need to be very clear on what conditions these sleeping bags are best for, how to use them, and if they are a fit for the situations they want to use them.

2. Look for Slimmer Sleeping Bags, Not Roomier

The shape of a sleeping bag also plays a role in how warm it can keep you. Since sleeping bags retain our body’s warmth and keep it within, a slimmer sleeping bag would also be much warmer than a larger one.

The more space you have, the less warm you will be. Therefore, if you want a lightweight sleeping bag with high thermal efficiency, you shouldn’t expect to have a lot of room.

3. Do Not Over-Rely on the Temperature Ratings on the Sleeping Bags

The manufacturer’s temperature ratings noted on the products are standard in most insulated items. However, they shouldn’t be necessarily trusted as sometimes they might not be as accurate. Regardless, they should give you a general idea of what temperatures they cannot withstand.

To be on the safe side, a common practice is always to get items that can withstand temperatures lower than the weather you will be camping in. This is because you shouldn’t try to test your equipment but instead always plan to deal with the worst-case scenario. These temperature ratings refer to what kind of temperatures the bag would be able to keep you safe from the cold, but not necessarily warm.

4. Do Not Purchase Equipment Without Having the Proper Knowledge/Skills

Having the appropriate equipment is essential for a successful and safe experience in the wild. However, it is imperative to have the knowledge and skills to operate the equipment and survival skills before you buy it.

Purchasing a lightweight and down-insulated sleeping bag with high fill power doesn’t mean you will be warm during cold nights. You must know how to protect yourself from the elements, make yourself warmer, and ensure your safety. Without these critical skills and knowledge, there is no point in purchasing any equipment.

5. Do Not Be Cheap if You Want Something That Will Last

In most cases, when it comes to the price of a sleeping bag, the saying is true; you get what you pay for. If you take venturing into nature seriously, then you should know it is best to invest in your gear. From camping pillows, durable tents, to camp cookware, quality gear will last you through multiple camping and backpacking trips. Your sleeping bag is perhaps one of the most important things you need while in the wild, so if you decide to spend less on it, you might regret it sooner or later.

Specifically, an ultra light sleeping bag generally cost more, so investing in a good one with high fill power, water resistance, and durability is always money well spent. This is especially true for those who frequently spend a lot of time in nature. The more you use it and reap its benefits, the more you get your money’s worth.
