Using compression sacks to minimise size

Compression sacks are a great way to minimise the size of your sleeping bag when attached to your backpack. They are designed to compress bulky items like sleeping bags to a third of their size, freeing up valuable space in your backpack.

Firstly, you need to determine the volume of your sleeping bag. This can be done by measuring the radius of the circular base and the height of the stuff sack in inches. Then, multiply 3.2 by the radius, by the radius again, and then by the height. Finally, divide by 61 to get the volume in litres. Alternatively, you can use the metric system and measure in centimetres, dividing the total by 1000 to get the volume in litres.

Once you have the volume of your sleeping bag, you can choose the right size of compression sack. It is recommended to get the smallest size possible that fits your bag. Down sleeping bags are more compressible than synthetic ones, so they require smaller sacks. Synthetic bags will need a higher-volume stuff sack and may even require a compression sack to reduce the volume in your backpack. If you are backpacking, you will want to compress your sleeping bag as much as possible to save space. However, if you are car camping, a regular stuff sack will suffice.

Some sleeping bags come with their own compression sacks, specifically designed to fit the bag's size and volume. These bundled options offer better value and ensure maximum compression without damage. The sack's material and design complement the sleeping bag's fabric and insulation type, enhancing protection and durability.

When choosing a compression sack, also consider the level of compression you need and whether you require waterproof features. For example, the eVac Compression Dry Bag LW is lightweight and water-resistant, making it ideal for external mounting.

Attaching to backpack straps

Attaching a sleeping bag to your backpack's straps can be done in several ways, depending on the type of backpack and sleeping bag you have. Here are some detailed instructions for attaching a sleeping bag to backpack straps:

  • Compression Straps: If your backpack has compression straps, you can loosen the buckles, slide your sleeping bag under them, and then tighten the straps to secure the bag in place. Compression straps are often found on the sides of backpacks, but if your backpack has them at the top or bottom, it's better to use those to avoid an uneven feel when carrying the pack. This method works well if your sleeping bag is compact and doesn't take up too much space.
  • Gear Loops: Many hiking backpacks feature gear loops specifically designed for attaching gear like sleeping bags. If your backpack has gear loops at the top, they are ideal for attaching your sleeping bag. If your sleeping bag stuff sack has adjustable straps, you can attach them to the gear loops. Pull the straps tight to prevent the sleeping bag from swinging around as you move.
  • Bungee Cords: If your backpack doesn't have long enough straps or dedicated gear loops, you can use bungee cords. These are elastic cords with a hook on each end. With internal-frame backpacks, attach one hook to the daisy chain or compression straps, crisscross the cord over the pack, and then attach the second hook on the other side. For external-frame backpacks, simply attach the hooks to the frame. This method adds a little extra weight to your gear.
  • Lid or Top Flap: Some backpacks have a lid or top flap that can be used to secure a sleeping bag. After packing your bag and zipping it closed, open the top flap, place the sleeping bag on top, and then fasten the flap over it. This keeps the sleeping bag secure and centred, making it easier to carry. However, if your backpack is already packed full, this option may not work.
  • Tie Points: Many backpacks have tie points at the bottom, which can be used to secure bulky items like sleeping bags. If your sleeping bag stuff sack has loops, you can attach them to the tie points using a carabiner or cord. However, this method may cause the bag to swing around, so additional carabiners or cords may be needed to stabilise it, adding extra weight.

When attaching a sleeping bag to your backpack straps, it's important to consider the weight distribution and balance. Attaching a sleeping bag to the sides can make the pack feel uneven. Try to balance the weight by distributing other gear evenly or using the lid or top flap method to keep the weight centred. Additionally, ensure that the straps or cords you use are long enough to accommodate your sleeping bag when fully extended.

Attaching to gear loops

Attaching your sleeping bag to your backpack's gear loops is a viable option if the bag's stuff sack has loops. You can use a carabiner or cord to attach the bag to the gear loops. However, it's important to note that this will cause the bag to swing around as you move. To prevent this, you can use two carabiners or extra cord to keep the bag stable, but this will add weight to your kit.

If your backpack has dedicated gear loops for bulky items, you can use them to attach your sleeping bag if the straps are long enough. It's important to consider the weight distribution when attaching a sleeping bag to your backpack. Adding several pounds to one side can alter the pack's weight distribution and make it tricky to balance while hiking.

To address the weight distribution issue, you can try to balance out the weight on the other side. Additionally, make sure that the compression buckles on your pack can handle the strain, as they have a tendency to pop open.

Another option is to use bungee cords, which are elasticated cords with a hook on both ends. With an internal-frame backpack, attach one hook to one side of the pack and then crisscross the cord several times before attaching the second hook to the other side. For added security, you can loop the cord through the bag's stuffing sack straps. If you have an external-frame backpack, simply attach the hooks to the frame.

When attaching your sleeping bag to gear loops, it's important to ensure that your attachment points and sleeping bag are compatible. It's also a good idea to use a compression sack to squeeze your sleeping bag into a more manageable size, making it easier to attach.

Using bungee cords

Bungee cords, also known as shock cords, are a great way to attach your sleeping bag to your backpack, especially if the straps on your pack aren't long enough and there's no room under the hood. These cords are elasticated and have a hook on each end. Bungee cords are designed to provide extra storage space outside the main compartments of your backpack. They are ideal for securing bulky yet lightweight items, such as a sleeping bag, as the elastic cord can grip onto the item and keep it in place.

Here's a step-by-step guide on how to use bungee cords to attach your sleeping bag to your backpack:

  • If you have an internal-frame backpack, attach one of the hooks to one side of your pack. You can attach it to the daisy chain or compression straps.
  • Crisscross the bungee cord over your backpack several times, ensuring that it passes through your bag's stuffing sack straps for added security.
  • Attach the second hook to the other side of your backpack.
  • Adjust the tension on the bungee cord by locating the cord lock and sliding it along the cord to tighten or loosen as needed.
  • Shake your backpack to confirm that your sleeping bag is secure and doesn't slide or move. If it does, adjust the tension again.

It is important to note that bungee cords are stretchy and designed for lightweight items. If you attach something very heavy, it might bounce around more than if you used a non-elastic shoulder strap. Additionally, always check and double-check that your sleeping bag is securely attached and is not at risk of falling off or getting damaged during your hike.

Waterproofing considerations

Waterproofing is an important consideration when attaching a sleeping bag to your backpack. While some sleeping bags are designed with hydrophobic down and water-resistant shell fabrics, not all sleeping bags are waterproof. Therefore, it is essential to take the necessary precautions to ensure your sleeping bag stays dry while attached to your backpack.

One option is to use a waterproof pack liner or a compression sack with a waterproof construction. This will help to keep your sleeping bag dry in case of rain or if you need to cross a river. Compression sacks are also useful for minimizing the packed size of your sleeping bag, making it easier to attach to your backpack. However, it is important to note that compression sacks can permanently damage the down of your sleeping bag if stored for extended periods.

Another option is to use a dry bag, which is a popular choice among those hiking in wet climates. A dry bag will keep your sleeping bag and other belongings dry, even in rainy conditions. Additionally, some sleeping bags come with a waterproof panel around the feet, providing added protection from moisture.

If you are attaching your sleeping bag to the outside of your backpack, consider using a waterproof sleeping bag cover or a raincover for your backpack. This will help protect your sleeping bag from the elements and ensure it stays dry. Properly waterproofing your sleeping bag is crucial, especially if it is down-filled, as down feathers lose their ability to insulate when wet.

When choosing a sleeping bag for backpacking, look for one that is light, warm, and compressible, such as those filled with down. Down sleeping bags are highly compressible, making them easy to attach to your backpack. Additionally, look for sleeping bags with high-quality zippers that don't snag and provide adequate ventilation in warm weather.
