A Guide In Choosing The Best Backpacking Sleeping Bags

A backpacking sleeping bag is an essential gear for backpackers, hikers, and outdoor enthusiasts. But of course, I can't guarantee that all sleeping bags that you can see today are worthy of being taken in your next adventure. 

There are several things that you need to consider when choosing a sleeping bag, especially when you are going to use it on your weekend off-grid trips. I've simplified these considerations below. 

Temperature Rating

For most backpacking pursuits, warmth is something that you shouldn't ignore. Hence, you wouldn't want to get a sleeping bag that doesn't have enough insulation. Terms like "lower limit" and "comfort" are often laid out. But what do they mean?

The lower limit refers to the temperature where a typical warm sleeper can feel comfort. Meanwhile, the comfort rating is the temperature where a typical cold sleeper can feel comfort. These figures are crucial, but they aren't that absolute. After all, the aspect of comfort is something subjective. It can also be susceptible to various influences, such as the size of the sleeping bag and condensation. 

Hence, it is recommended that you pick a sleeping bag with a lower temperature rating than what you actually need. In this way, you'll have room for adjustment. 

Type Of Insulation

There are two types of insulation used on sleeping bags: down and synthetic. 

Down insulation is made from plumage and feathers from ducks and geese. But make sure that they have RDS certification to ensure that they have been taken ethically. Down excels when it comes to warmth retention and weight management. It is also packable because it is easy to compress. Durability-wise, down is also superior to synthetic. However, if they get wet, it's difficult for them to dry. At the same time, they lose their insulation. 

Synthetic insulation can perform even if it is wet. It is also affordable, which makes sleeping bags with synthetic fills cheaper than their counterparts. Because of this particular feature, synthetic sleeping bags are ideal for budget-conscious backpackers and casual outdoor goers. 

Packability

The packability of a sleeping bag is a crucial aspect that you have to take into account. Keep in mind that we are talking about backpacking here; the latter is about weight and bulk management. Essentially, you don't want something that is too heavy and bulky to carry. 

Here, down sleeping bags are appealing options. As I've said, they are compressible and don't weigh much. Synthetic sleeping bags, on the other hand, may cause you a problem in this particular department. But of course, there are selected options, such as the Marmot Trestles Elite Eco 20 and REI Co-op Trailbreak 20 Sleeping Bag, that address this problem properly. 

If you are searching for an ultralight option, expect that there will be compromises. Insulation will be reduced since the sleeping bag has been shredded with its down or synthetic fill.

Shell Durability

The durability of the sleeping bag's shell is important. It is the one that protects you and the insulation from the elements. Hence, you would want it to be as impervious to damages as possible. 

But how would you know if a particular shell is durable? Well, you can check its fabric's denier. Denier is the measurement for the thickness of the fabric. A higher number suggests that a piece of fabric is thicker, which, in a sense, is more durable. 

Furthermore, it would really help if the shell had a durable water repellent (DWR) finish. In this way, moisture can't bypass the shell. 

In Summary

The best backpacking sleeping bags provide the utmost comfort and protection to their users. If you are a backpacking enthusiast, you have to have a reliable sleeping bag in your arsenal. It is a necessary investment since you can't just entrust your convenience in your tent alone. Just remember to take into account the considerations that I've listed so that you can pick the most suitable sleeping bag for you. 

And since you are here, why not just check on the sleeping bags that I've listed?
