Buying Guide

There is a huge variety of 0 degree sleeping bags out there. The best one will be able to keep you alive and comfortable even in extremely cold weather. For that, let’s see what features make a great sleeping bag.

Temperature Rating

The temperature rating of a sleeping bag indicates the lowest temperature to keep warm while using it. Most manufacturers don’t use a standard rating system and it varies from manufacturer to manufacturer. Besides, everyone’s body temperature and comfort levels are different.

Nowadays many major brands use the European Norm (EN) 13537 Testing Protocol for labeling sleeping bags. Experts suggest purchasing a sleeping bag rated at least 5-10 degrees below the average temperature while using the bag in. Also, you should wear warm clothes and use sleeping pads even when using 0 degree sleeping bags.

Insulation Type

Insulation directly influences temperature rating and warmth thus being responsible for keeping warm. Better insulated sleeping bags trap the body heat inside the bag and keep your body warmer at night. Generally, there are different types of materials used as insulation for sleeping bags. There’s been much debate between down and synthetic as in which one is better. However, there’s another material to consider nowadays.


Down offers the best warmth to weight ratio. Moreover, it’s more durable, light, and easy to carry. That’s why it’s a great choice for 0 degree sleeping bags. However, down is an expensive material, and getting wet, it loses its insulation ability.


Synthetic sleeping bags are commonly made from polyester and the least expensive option. It is better for people suffering from allergies. The material is durable and even after getting wet, the bag dries easily. The only downside is it takes much space and bulkier, therefore harder to pack up.

Water-Resistant Down

It combines the better of the two materials. A lighter, warmer, portable sleeping bag but it won’t get damaged even with getting damp. The exclusive benefits come with a premium price as well. Other than that, this the best insulation option for sleeping bags.


For any backpacking/camping trip, ultralight and portable gear is a must. A lightweight and easy to pack sleeping bag will help you immensely in this regard. 0 degree sleeping bags are specifically suitable for winter trips, so you need to consider the warmth and weight both.

Light sleeping bags tend to have less insulation fill, whereas heavier bags provide more heat but a pain to carry everywhere. In fact, high quality down (800 or more) has a lower temperature rating and lower weight as well. However, these usually cost more than average sleeping bags.

Your trip preference also plays a larger part, as backpacking needs lightweight gear but camping trips demand heavier and bulkier sleeping bags.


The shape of the sleeping bag is to be considered seriously because the less space there is, the warmer you can be.

The bags come with a variety of shapes so that you can select according to your body type and preference. The most common types out in the market are rectangular and mummy bags.


These bags have a slim cut, contoured hood, and snug fit. The shape restricts movement but provides the most warmth.


The simple rectangular shape offers more room to move around and less restrictive. But they provide less warmth and more suitable for mild weather.

Semi Rectangular

These bags have more of a “barrel” or “modified mummy” shape. Also, having both the characteristics of mummy and rectangular shapes, they combine comfort and warmth.

Most of the 0 degree sleeping bags come in mummy shape as these are more suitable for cold weather. The rectangular bag will give you comfort, but mummy bag will actually save you from the bite of cold.


Sleeping bags also come in a variety of sizes. Along with shapes, size is another factor worth considering.

Adult Sleeping Bags

Most bags come in 3 sizes-small, regular and large. Your bag should match your height and physique. If you can then try your size and the next one to compare which one is the better fit for you. Generally, you’ll be warmer and save a little weight by going with the smaller of the two sizes.

Women’s Sleeping Bags

These are catered towards women to closely fit an “average woman’s” contours. They are typically shorter, narrower at the shoulders and wider at the hips. Also, they come with extra insulation in the body and foot area.

Kids’ Sleeping Bags

These are simply shorter and smaller variations of adult sleeping bags but more affordable. Moreover, brands still provide an estimated temperature rating for kids’ bags, even though ISO and EN testing can’t be done on them.

Additional Features

Here, let’s look at some bonus features you may want to consider before buying:


Camping in cold temperatures, people lose a lot of heat if their heads are uncovered. All the best 0 degree sleeping bags come with a built-in hood with a drawcord to pull tightly around your head. The hood prevents the heat from radiating away thus keeping your head warm along with your body.

Draft Collar

A draft collar is a tube of insulation that drapes over the chest and neck and seals in the bag’s warmth. It’s there to limit the amount of cold air that enters the bag. It is perfect for cold weather sleeping bags, as it’ll ensure the bag stays warm and the heat doesn’t escape from the bag.

Draft Tubes

Draft tubes are tubes of down that cover up the side zipper. Most winter bags have at least one zipper draft tube, although some have two, both top and bottom, that fall into place while zipping up the bag.


Most sleeping bags come with different zipper lengths. Full-length zippers offer easy access and ideal for ventilation. Short length zippers provide less flexibility and open at just halfway. Zippers getting caught in the way and breaking down frequently will make your camping experience a nightmare. So, good quality snag-free zippers are a must. 0 degree sleeping bags are for winter weather so the zippers need to be extra strong and durable.

Shell and Lining

The outside material of the sleeping bag is called the shell, while the inside material is called the lining. The shell is designed to repel water and the lining is designed to disperse your sweat during the night. Nowadays, many synthetic fill sleeping bags offer a shell fabric with a durable water repellent (DWR) finish. Generally, polyester or nylon breaths and draws away moisture and cotton/flannel are comfortable but you’ll be left feeling wet.

Sleeping Pad

It works as a layer between your sleeping bag and the cold ground thus adding better insulation. It protects the sleeping bag from ground frost or low temperature at night. Invest in the best and lightest sleeping pad, and get added warmth and comfort.

Pillow Pockets

Some sleeping bags come with a small pocket which can be converted into a pillow by stuffing some soft clothes inside it. If you have a habit of sleeping with a pillow but can’t bring one to your camping trip, then it can be a nice alternative. You’ll be getting not only comfort but also extra warmth for your head.

Foot Box

It’s the space at the bottom of the sleeping bag. Some bags also come with an extra insulated footbox so that your feet remain warm. If you sleep on your sides or turn over a lot at nights, then look for a more spacious footbox.


Hopefully, our review helped you to learn more about the best 0 degree sleeping bag and where to find it. When you start comparing more and more models, you’ll definitely find what you’re looking for. So, think about your preference and requirements for 0 degree sleeping bags and choose according to it.
