Not only are they affordable, but they have great features not present in other materials. Now read through as we unfold the best synthetic sleeping bag for you. But, it’s imperative to get yourself familiar with the critical considerations that are prerequisite to choosing the best sleeping bag. Like other outdoor apparels, sleeping bags come with various competitive features.

Even though, some features like temperature rating, waterproof, and warmth seem common, they differ in measurements. We will discuss some critical considerations below that will help you pick the best synthetic sleeping bag among hundreds.

Features to Consider

Among other considerations, we’ve chosen the warmth, waterproof, temperature rating, comfort, and weight of the synthetic sleeping bag. We know that some may consider the affordability as the main factor for choosing the best sleeping bag.

Warmth

In general, sleeping bags do not create warmth at all, but help retain your body heat. The fibers of the sleeping bags help trap the body heat as long as possible so that you can feel warm throughout your sleep. That’s why almost all sleeping bags have insulation materials to help retain heat and provide you the best warmth. The synthetic sleeping bags are engineered to resemble the characteristics of natural insulating materials such as Down in providing the best warmth.

It is thus important to assess the sleeping bag’s strength of the insulating material used. Some are filled with the Gore-Tex, eVent or HyVent as the insulating fibers and each has a strength. A tip of advice, the interior space of the sleeping bag plays a significant role in your warmth. That being said, larger sleeping bags may not be as efficient as the small ones in retaining maximum heat. It may take long before you get warm because of the larger area.

Temperature Rating

The temperature rating is also a critical consideration that helps you understand if a typical sleeping could be suitable for your camping destination. Before choosing a certain temperature rating, you have to observe the climatic fluctuations of your preferred destination. Choosing the wrong rating may compel you to take additional layers of blankets just to survive the freezing temperatures.

Some sleeping bags may rate between 15 degrees to 35 degrees Fahrenheit for spring, summer and fall vacations. For winter vacations you will need a different set of ratings. Supplementing your sleeping bag with a sleeping pad for warmth is another way of boosting the temperature rating. We do encourage that because some locations can puzzle you with their temperature fluctuations. Rather stay prepared for any inevitable climatic condition.

Weight

Synthetic sleeping bags are generally bulky and heavy-weight compared to their natural counterparts. Nonetheless, there are still some great deals of weight out there. Having a sleeping pad, sleeping bag, and the backpack imposes lots of weight tension in your body. The remedy is to look for light-weight synthetic sleeping bags for a minimalist hiking adventure.

It is also helpful to map out your hiking trajectory to see if a heavy weight gear will not have a negative impact on you. For example, ascending summits require minimalist sleeping bags. All you need is a balance between warmth and weight. With regard to synthetic sleeping bags, the heavier the warmer. Only a few can mimic the inverse proportion of Down-filled sleeping bags where lightweight bags are the warmest.

Comfort

The concept of comfort in synthetic sleeping bags is actually subjective. Many people perceive comfort in various ways. For example, having a larger sleeping bag in which you can freely stretch your legs can be viewed as the best comfort by some, whereas others view comfort as having the tightest sleeping bag that retains heat fast.

In our view, as long as the sleeping bag has a proper fit, an ample foot box, the best waterproof, and other features, it is comfortable. The comfort and the advantage of sleeping bags is that they can still keep you warm and dry even when damp. They also dry fast if it had rained on them.

Water Resistant

The DWR (Durable Water Resistant) coating has become the standard coating of many sleeping bags due to its ability to repel water in case it rains on the sleeping bag. The water drops will just roll on the fabric without being absorbed.

Even if it gets absorbed after the coating has deteriorated, some sleeping bags have excellent waterproof linings that can prevent penetration of water into the bag. The advantage of the DWR is that it can be restored if you notice that it is no longer effective. Having this coating on your synthetic sleeping bag helps a lot.

Other Accessories

In addition to the aforementioned considerations, some sleeping bags have additional accessories that also play a pivotal role in the overall functionality. For instance, a hood is a great addition to provide warmth to your head.

Otherwise, you will have to wear a cap to compensate for that, more especially if the sleeping bag does not extend to your head. Also worth considering is the availability or amount of zippers is also a good addition because they will help retain heat.

  • Aimee Stafford

    Synthetic sleeping bags seem to have a lot of upside after I read this article, but they’re very stuffy for me. There’s not much circulation and my sweat gets stuck on the inside. Is this normal? How can I fix this?

  • Rebecca J. Crawford

    You find one that has venting in the foot bed to help air circulate better. Look for one that is made to allow air to circulate well.

  • Andre Mahe

    While going through this I found the products that you are given are having some great features. Is there anyone who can recommend something which is not take too much of space to carry?

    • Rebecca J. Crawford

      Check the weights on the bags we mentioned for something light weight. Sleeping bags are going to have bulk, so you have to decide on warmth or bulk in some situations.
