Backpacking 101: Packing A Sleeping Bag Efficiently

how to pack a sleeping bag for backpacking

Sleeping bags can be bulky, even when compressed, so it's important to consider the best way to pack them for backpacking. The make and model of your sleeping bag and backpack will determine the best packing method, but there are some general strategies that can help. One common method is to place the sleeping bag at the bottom of the pack, especially for short trips or well-trodden paths. This frees up internal space for essentials like food and water. Another option is to attach the sleeping bag to the outside of the backpack using straps, keeping in mind that this may not be comfortable for some hikers. To protect your sleeping bag from moisture, use a waterproof compression sack or a dry bag, especially if your backpack does not have a built-in rain cover.

Sleeping bag compression sacks

When choosing a compression sack, it's important to consider the size. Compression sacks come in a range of sizes, typically measured in liters or cubic inches. For a sleeping bag, you'll likely need a larger size, such as a 35-liter option, or even larger if you're using it as a backpack liner. However, it's worth noting that some sleeping bags, especially those rated for colder temperatures, may require a size larger than expected. Additionally, consider the type of closure and compression mechanism. Some compression sacks use a one-way purge valve to release trapped air, while others use permeable fabrics like eVent to allow air to escape while keeping water out. Compression straps are also a common feature, allowing for thorough and even extraction of air.

It's worth noting that compression sacks are not always waterproof, so you may need to use a waterproof pack liner or dry bag in addition to your compression sack. Alternatively, you can choose compression sacks that are made with waterproof or water-resistant materials, ensuring your gear stays dry. Some popular options include Sea to Summit's Ultra-Sil compression sacks, which are lightweight and available in a range of sizes, and Hyperlite's compressible stuff sacks, which are made with waterproof DCF Dyneema fabrics. Granite Gear's Round Rock Solid compression sacks are another durable option, made with sturdy 210-denier nylon.

When packing your sleeping bag into a compression sack, it's recommended to place the sleeping bag first at the bottom of your backpack, especially if it's a down bag. Then, you can add heavy items on top of the sleeping bag, closer to your back, and finish with lighter gear. This helps distribute the weight comfortably. Additionally, consider using multiple smaller compression sacks to separate and organize your clothing and gear, making it easier to access specific items without decompressing the entire bag.

Waterproofing

Waterproof Compression Sacks

Sleeping bag compression sacks are often not waterproof, so it is recommended to use a dry bag or a waterproof pack liner. These bags are specifically designed to keep water out and come in various sizes to fit the bottom of your backpack. Some popular options include silnylon stuff sacks and ultrasil or DCF dry bags.

You can use waterproofing sprays, such as DWR (Durable Water Repellent), on your sleeping bag to aid in water resistance. However, it's important to note that these sprays will not make your sleeping bag completely waterproof. They are designed to aid liquid water to run off and won't stop water vapour from escaping, which is important for breathability.

Plastic Bags

If you're concerned about the bottom of your sleeping bag getting wet, a simple solution is to place the end of your sleeping bag inside a large plastic garbage bag or use a lightweight rescue blanket. This will create a physical barrier against moisture.

Waterproof Down

Some sleeping bags are now being offered with waterproof down fillings. This type of down is resistant to absorption from humidity and vapour, which can help keep your sleeping bag from feeling damp in the morning. However, there are mixed opinions on its effectiveness, with some people concerned about clumping and loss of loft.

Bivvy Bag

If you're expecting very wet conditions, consider using a bivvy bag. A bivvy bag is a waterproof cover for your sleeping bag that will provide an additional layer of protection from the elements. It is a more extreme solution but may be necessary in certain situations.

Attaching to the backpack

Attaching your sleeping bag to your backpack is an art. If your backpack has built-in straps designed to attach a sleeping bag, you're in luck! Here is a step-by-step guide to attaching your sleeping bag to your backpack:

  • Lay your backpack flat on the ground, with the front side down. Ensure that all the straps are unbuckled and untangled.
  • Compress your sleeping bag. Some sleeping bags can be compressed into a stuff sack or a compression sack. If your sleeping bag is synthetic, it may fit and compress well using your backpack's sleeping bag compartment and straps. Down bags are more compressible and can be compressed into smaller spaces.
  • Protect your sleeping bag from moisture by using a waterproof compression sack or a dry bag. If your bag is not waterproof, you can line your backpack with a waterproof bag or use a rain cover for the entire pack.
  • Place the sleeping bag at the bottom of your backpack. This is a classic and generally good choice, especially for hiking on well-trodden paths or relatively short trips. It frees up internal space for other essentials like food, water, and clothing.
  • If you prefer not to store your sleeping bag inside your backpack, you can sling it under your backpack or strap it to the top. This method may make your pack heavy in the middle, which some people might find uncomfortable.

What to pack first

When packing for a backpacking trip, it's important to consider the size and type of your backpack and sleeping bag, as well as the duration of your trip and the climate you'll be hiking in.

To begin, it's recommended to use a backpack with a bottom compartment that is separated and has its own zipper. This will allow you to access your sleeping bag without having to unpack your entire bag. If your backpack doesn't have this feature, consider purchasing one with built-in straps designed to attach a sleeping bag. Alternatively, you can compress your sleeping bag and place it at the bottom of your backpack, especially if you're hiking on well-trodden paths or taking shorter trips.

Before placing your sleeping bag in your backpack, consider using a waterproof compression sack or a dry bag to protect it from moisture. Sleeping bag compression sacks are not always waterproof, so a dry bag can be a good alternative. You can also line your entire backpack with a nylofume bag for added water protection.

If you're using a sleeping pad, it should be placed inside the backpack first, vertically, and folded to conform to the entire back panel. This will provide a flat surface for your sleeping bag and help reduce the overall volume of your kit.

Now, you can place your sleeping bag inside the backpack. If you're using a compression sack or dry bag, simply stuff it into the bottom of the backpack. If not, you can try the "burrito" technique by rolling your sleeping bag and sleeping mat together. Place heavy items between the sleeping bag and sleeping mat, closer to your back, and then add the rest of your gear on top.

Backpack size and type

The size and type of your backpack are crucial factors to consider when packing a sleeping bag for backpacking.

Firstly, it is important to ensure that your backpack is large enough to accommodate your sleeping bag and other essentials. If you have a small backpack, you may struggle to fit everything inside, especially if you have a bulky sleeping bag. For instance, a 40L bag may not be sufficient for overnight backpacking, as it could leave little room for other gear. In such cases, a bigger backpack or a smaller sleeping bag may be necessary.

Down bags are generally more compressible than synthetic bags, so if you're looking for a bag that will take up less space, down might be the better option. The compressibility of your sleeping bag will also determine how small it can be packed. Some bags can be compressed to the size of a soccer ball, while others may be bulkier, even when compressed.

The type of backpack you choose is also important. Some backpacks come with built-in straps specifically designed for attaching sleeping bags, which can be very convenient. Additionally, a backpack with a separated bottom compartment and its own zipper can be useful, as it allows you to access your sleeping bag without having to empty your entire pack.

If your backpack does not have a built-in rain cover, consider purchasing one to protect your gear from moisture when it rains. It is also recommended to use a waterproof compression sack or a dry bag to keep your sleeping bag dry.

Ultimately, the size and type of backpack you choose will depend on your personal preferences and the specific needs of your trip.
