This is a backpack to help the wearer survive harsh streets or outdoors without having too much weight to carry around. This backpack is meant for homeless people with no means of shelter or food supply, but can be used for things like camping and travel.

Step 1: Step 1: Grab Your Materials

Some things you will need are:

a durable, but simple school backpack (depending on which method you will use you might not even need this)
waterproof drop cloth (most are)
army thread, or thread that can withstand wear and tear
any extra needed fabric that match the colour and style of the backpack
scissors
needle or sewing machine
a one person pop-out tent (or a children's tent)
sleeping bag
food that can be stored easily and for a long amount of time
a reusable water bottle with a filter in it
any other niceties you can think of (toiletries, emergency blankets, hygiene care products, etc.)

All can be found at convenience stores and supermarkets, and most can be found under the camping section.

Step 2: Method 1: Creating Your Own Backpack

This method is one of the easiest methods you can do, but requires the ability to sew and draft things relatively well. Full and explanatory instructions can be found through this link(along with the materials listed here, you will need your drop cloth for waterproofing the backpack).

Step 3: Method 2: Reconstruct Your Backpack

This Method requires more time and effort than the first one, because you are taking apart the backpack you have and adding the drop cloth in between you two sheets of fabric. Estimatedley, this will take a day and a half.

In order to do this method, you will need:

Scissors
A de-stitching tool (if you don't have one on hand, you can use tweezers or a needle, but the de-stitching tool is easiest)
A needle and thread (for this, it is best you use a thicker needle, possibly one used for tapestry, and army thread is preferred)

All you really need to do is take apart the seams and add in the drop cloth. Make sure when you're sewing everything back together, it stays as a recognizable backpack. for an example, you can regard to this instructable and use it as an extremely loose guideline.

Step 4: Method 3: Sewing the Drop Cloth Onto the Backpack, But Not So It Is in Between Other Fabrics.

This method is considerably easier than method 2, but less durable and reliable on the actual act of waterproofing. Through this method, you turn the backpack inside out, wrap the drop cloth around the main pocket, and cut out the needed fabric measurements. Then, proceed to tightly stitch your cloth onto the fabric, but not so you can see the thread on the outermost layer of fabric. For this method , you will need the same materials as before.

Step 5: Step 2: Finalizing

After you have finished your preferred method of creating this backpack, all you need to do is add your needed supplies, and share it with the world! You can use it for camping with friends and family, or give to a person who's stuck toting around a shopping cart under a bridge. You decide whatever you want to do with it! Have fun and be creative!
