How to Attach a Sleeping Bag to a Backpack

by Alex Wittle

While it's best to store your sleeping bag inside your backpack, sometimes that's not possible due to limited space. Your sleeping bag is often the bulkiest item, along with your sleeping pad, tent, and tent poles, so attaching it outside your backpack can be a smart solution. In this guide, we'll walk you through how to securely attach it.

You can attach nearly any sleeping bag to the outside of your backpack. But a lightweight, compact, and waterproof bag that compresses well works best. Also, make sure the bag is weather-resistant, as it will be exposed to the elements when carried outside your pack during a camping trip. Lastly, when it comes to the backpack itself, sleeping bags attach well to an internal frame backpack.


Do You Need Compression Sacks?

Yes, it's highly recommended. It helps reduce the size of the sleeping bag which in turn makes it easier to attach to your backpack. It also protects the bag from dirt and moisture. Go for a waterproof compression sack to protect your bag from the elements.

Here’s a step-by-step guide to help you attach a sleeping bag to a backpack:


  • Let your sleeping bag dry before you pack it up.
  • Once it's completely dry, place it into the compression sack or stuff sack to reduce the size.
  • Most backpacks have built-in adjustable straps on the bottom, sides, or top for attaching gear. Locate these straps on your backpack.
  • If your sleeping bag doesn’t come with sleeping bag straps, use separate compression straps or straps with buckles. These are available at most outdoor stores.
  • Position the compressed sleeping bag at the bottom of your backpack if you have bottom straps. If you use side or top straps, place them accordingly.
  • Thread the compression straps or backpack straps through the loops on your sleeping bag or around the sleeping bag itself. Tighten the straps until the sleeping bag is secure and doesn’t move.
  • Secure the sleeping bag tightly and make sure it's evenly distributed and doesn’t shift the balance of your backpack.
  • If there’s a chance of rain, use a rain cover for your sleeping bag. Some backpacks come with built-in covers, or you can purchase one separately.
  • Before heading out, double-check all the straps and attachments are tight and secure.

Alternate Methods to Attach a Sleeping Bag to a Backpack

If the standard method doesn’t work for you, here are five alternate methods to attach your sleeping bag to your backpack:


1) Use Carabiners

Carabiners are versatile clips that can attach a sleeping bag to your backpack. Loop one through the straps or loops on your sleeping bag and then clip it to the gear loops or daisy chains on your backpack. Make sure to use strong carabiners that can support the weight of your sleeping bag.


2) Bungee Cords

Bungee cords are flexible and can secure a sleeping bag in various positions. Wrap a cord around the compressed sleeping bag and attach the hooks to your backpack’s gear loops or compression straps. Make sure the cord is tight enough to hold the bag securely but not too tight to cause damage.


3) Webbing Straps

Webbing straps are ideal if your backpack has multiple attachment points. Thread the straps through the loops on your sleeping bag and then attach them to the backpack’s webbing loops. Tighten the straps to ensure the sleeping bag is secure.


4) Sleeping Bag Compartment

Some backpacks come with a dedicated sleeping bag compartment, often at the bottom. If your backpack has this feature, place your compressed sleeping bag into the compartment. This keeps it separate from the main compartment and easily accessible.


5) DIY Attachment Points

If your backpack does not have proper attachment points, you can create your own. Use a strong, durable cord or rope to create loops on your backpack. Attach the cord to stable parts of the backpack frame or straps, then use these loops to secure your sleeping bag with carabiners or straps. Make sure your DIY solution is strong enough to hold the weight of the sleeping bag.
