Below, we are going to look at simple steps for DIY sleeping bag liner and the importance of including it in your backpack.

Why do You Need a Sleeping Bag Liner?

It is common for a hiker to start camping season early and end late. If you do this, it means that you usually sleep in temperatures lower than your sleeping bag rating. To add temperature to your sleeping bag, you will require adding a Microfleece or a standard fleece liner. Additionally, sleeping bag liners also play an invaluable role when it comes to maintaining the cleanliness of your bag.

Unfortunately, sleeping bag liners tend to be the most undervalued items in the hiking gear, despite being lightweight and extremely packable. Before you underestimate the need of using them, ask yourself how long you would be willing to use your duvet without bed sheets or duvet cover. The liner plays the same role as the sheets and the cover, providing an easily removable barrier between you and the sleeping bag.

Steps for Sewing DIY Sleeping Bag Liner

  1. Lay the sleeping bag on a flat surface and determine its size when the zipper is closed. Double the size to determine the amount of material you will require purchasing. Once you have all the supplies at hand, roll the packing paper on the floor and place the bag on top completely zipped. Using the magic marker, trace the shape of the bag on the paper. Ensure that even after tracing the hood, you also draw a line just below the chin marking where the top side of the bag ends.
  2. Remove the sleeping bag and cut out the shape to create a paper pattern. Now lay your textile on a flat surface and double it just like a folded sheet. Lay the paper trim on top of the sheet and make sure the pattern edges are near the folded edge of the fabric and pin it down if necessary.
  3. Carefully cut the fabric long the open side of the pattern and the open side, but do not cut the folded side.
  4. Using a yardstick, draw a rectangle on one side of the material to make a pillow pocket. The rectangle should have the same width as at the top of your sleeping bag, but with a 20 inches extension length so that it leaves enough space for the pillow. Use this pattern to mark and cut the head opening on the other side of the material. Cut the top side of the fabric in a straight across so as to allow flush with the sleeping bag.
  5. Once you are done cutting the fabric, fold it into half such that the side you don’t want against your skin is exposed. Approximate about an inch from the edge of the fabric and stitch the bottom and ¾ on the open side.
  6. While still in the same state, sew short pieces of ribbon or snap tabs on both sides all the way down the liner. These will help secure the liner to the sleeping bag suing two equally spaced attachments at the bottom and three on either side. They will also play a great role in helping remove the liner from the washing machine.
  7. Now, turn the sleeping bag inside out and place your newly mend liner on top of it and make marks on the fabric where the ribbons or snaps will go. Use a tack to stitch the attachments on the side of the bag and also hem the top side of the liner to prevent it from sliding when you get inside the sleeping bag.
  8. Hem the areas where the pillow pocket will go on the opposite side of the liner. To make sure it fits on the sleeping bag hood, double the hemmed extension into a rectangle. Make sure the rectangle is closed on three sides by sewing once vertical side, along the bottom and attached to the fabric underneath. The open vertical side will be for stuffing fleece or a puffy jacket to make a removable pillow.

Making a Zipper Sleeping Bag Liner

You can also choose to make a zipper sleeping bag liner, and while the two types serve the same purpose, a zipper one is a bit complicated to make. These are the steps for making such a liner;

  1. Fold your sleeping bag lengthwise and use your sleeping bag to trace its pattern on the newspaper roll using a magic marker. Make sure you include an extra 2-3 inches on each side for the seams.
  2. With the two sides still folded together, cut the folded side of the fabric. Then pin one of the sides fully before using a basting stitch to sew along that side with your sewing machine. A basting stitch is rather loose but not to worry since you will be removing it later.
  3. With one side of the fabric sewn, open it with the seams facing upwards and butterfly the edges. Where you want your zipper placed, and its length will determine the positioning. You should, however, make sure that the top edge of the zipper is close to the top of the bag. Also, leave excess material at the top of your fabric for finishing the edge of your liner opening.
  4. Line up the zipper with the lining you just created while it’s facing downward. Pin it in place and sew each side of the zipper. Once done, you can now remove the basting stitch made in step 2 above. Carefully pull and remove by cutting, the excess thread on the front side of the zipper. You can either use a seam ripper tool of sharp scissors if you don’t have the latter.
  5. With the hardest part of making your DIY sleeping bag liner, realign the edges so that you will have the right side of the liner is facing inwards. Then pin the open edges of the liner and sew the bottom and sew the seams. This last step gives you liner its shape, and it is almost complete.
  6. Fold and sew the top edge to finish your liner. Pull the pattern side of the liner such that it if facing out and hurrah, you are done.

Sewing a sleeping bag liner can take you approximately 1 hour, but if you are a sewing machine guru, then it will take even less.

Caring for your Sleeping Bag Liner

After sewing you handmade sleeping bag liner, you need to take good care of it to avoid repeating the task anytime soon. Make sure you regularly clean your liner to keep it fresh of sweats and body oils. While buying sewing fabric, make sure you choose the one that you are comfortable cleaning either by a washing machine or hand wash. It is also advisable to let your liner dry in natural air.

Make sure you are conversant with the right detergents to use on your liner. While most cleaning detergents are permitted, fabric softeners may interfere with your liner’s ability to absorb moisture, so use them sparingly. If you are using a washing machine, prevent the drawcords from being entangled in the machine by wrapping them in a pillow case. That way, you will have your liner in the right shape even after washing. Likewise, sleeping bags must be kept clean so read the piece on how to wash your sleeping bags.

    This sounds like a fun weekend project, I like that you can make it as simple or as complicated as you want. As a hiker it’s easy to get wrapped up in buying all the perfect gear but we forget that sometimes DIY is better! Thank you for this tutorial!

    • Henry Silva

      You are welcome. Have fun.

  • Kelly Harris

    This is such a cute and easy project, but I think I might end up using it inside another bag liner instead of just on its own. I would miss the insect shield on my store-bought sleeping bag liner. It just adds an extra layer of security that I wouldn’t want to be without on a night in the wilderness.

      Sounds great!
