A lot of people tend to get flustered when they have to make a bivy sack. However, there’s no need to be worried. All you have to do is follow these extremely simple steps, and you will have one in your hands in no time.

There are a couple of different materials you will need to make it. All of them are relatively common, and you can easily acquire them from your nearest hardware store.
Among the many different things you will need for this procedure, the first one will be Tyvek Home Wrap with a 15’ length and width of 3 feet. Other things include Velcro, some double-sided carpet tape, and Tyvek tape. The tools include a pair of scissors, a washing machine, a wallpaper seam roller, and a measuring tape.
Step 2: Getting the Measurements Right
Start by spreading out the Tyvek wrap across a plain surface and ensure that its length is similar to that of your sleeping bag. In fact, it’s best to extend the overall stretch by an extra foot or two. Bring the top sheet out and fold it at the end to ensure that the wrap doesn’t expand the entire extent.
The best way to allocate the area of the Tyvek wrap is to make it longer on the bottom. That way, you can easily pop your head out of the top when using it. It will ensure that your sight doesn’t get hampered when using the Bivy while your body and legs are perfectly protected.
Step 3: Start Taping
Now that the Tyvek wrap is set up, it’s time to get the edges closed off. Be sure to take into account which side of the sleeping has the zipper. It’s crucial to keep this thing in mind as you will be closing off the Bivy partially only. Seal off the side having no zipper completely while the sleeping faces downwards.
Mark the portion of the top sheet so that you can understand where to finish taping. Stuff the tape in the corners of the Bivy while leaving at least an inch untapped. Make sure that there is a bit of a gap between the end and tape to avoid any stickiness in the work portion.
Step 4: Seal, Fold, & Seam
Seal the seams by going for the corners first. Then, connect the top sheet to the tape while leaving 6” increments. Keep this process going unless the Bivy finally ends up complete.
Then have the corners folded after putting some tapes into the corner. Not only does it improve the overall aesthetics of the Bivy, but it also seals off the edges perfectly. Once the folding is done, all you have to do is invert the Bivy and seal off half of the seam.
Step 5: Prepare for Use!
There are a couple of steps that you have to go through before you can start using the Bivy. Start by crumpling it up so that you can reduce some of the stiffness and make it easier to move around. Stretch it out a few times to make it more manageable.
Give it a good cleaning by chucking it into a washing machine with nothing but cold water. You might have to do a little pushing to get it moving in the machine. Finally, once you’re done drying it, you have successfully completed the tutorial on how to make a bivy sack out of Tyvek!
