Your backpack is strong enough to hold everything you need thanks in large part to how it’s all put together. Here’s what you need to know!

Are Cotton Backpacks Good?
Cotton is typically mixed with canvas to make backpacks. This blend is a lot stronger than cotton on its own. Plus, it tends to look good and last longer than other materials.
So all in all, yes cotton backpacks are a good investment. Despite being more expensive than other materials, they’re stylish and durable enough to last for years and years.
What is the Most Durable Backpack?
Nylon is typically considered the most durable backpack material. It’s waterproof and able to withstand rugged terrains without getting damaged. For this reason, nylon is a wonderful material for outdoor use, especially when it comes to camping and hiking.
That isn’t to say other materials can’t be just as good. It really depends on why you need a backpack! For instance, leather and denim bags are better for everyday wear as they’re more fashionable and lightweight.
Overall, a well-made backpack is a good investment, regardless of the material. You would even do well to have a ton of different backpacks hanging in your closet at home!
Cut Paper Templates
The first step is to cut paper templates of each backpack part. These are essentially the blueprints or the frame for the manufacturer to use as they’re sewing the backpacks together later.
Cut the Fabric
Giant rolls of fabric (also known as bolts) are rolled out onto a table. This fabric can be cotton, canvas, leather, or some other material in a variety of colors and patterns.
Press & Mold the Fabric
Once the fabric is laid out, it’s cut to fit onto the paper templates from Step One. This is done using premade molds and a stamping press.
Sewing the Fabric
Each piece of the backpack is stitched together separately. This includes the front pocket, straps, zippers, and grab handle that’s at the top of some backpacks.
Add the Buckles
At this point, the manufacturer will add any extra details to the fabric, such as the adjustable buckles on the straps. Additionally, the custom design is printed, whether it’s a brand name, like JanSport, or a cute cartoon character.
Bring the Pieces Together
Once all of the individual pieces are sewn separately, they’re brought together with the same sewing machine. All that fabric now looks like a backpack!
Tweezers are used to pull out any loose threads in the fabric. The backpack is also cleaned and prepped for packaging.
The backpacks are now ready to go! They’re placed in cellophane wrap and shipped in giant boxes to retail stores like Target or Walmart. You will then see them on shelves or hanging on racks, especially around back-to-school season!

How Much Weight Can a Backpack Hold?
Backpacks made from a durable material like cotton canvas or nylon can hold about 30 to 40 pounds before they’re at risk of tearing. However, you should always carry less weight in your bag. A heavy backpack could hurt your back, neck, and shoulders, especially after prolonged use.
How Heavy is Too Heavy for a Backpack?
You should carry only 10% of your body weight inside of a backpack. So if you weigh 100 pounds, aim to carry about 10 pounds. Someone who weighs 300 pounds, on the other hand, can safely carry 30 pounds on their back.
This chart helps break it all down!
The more you weigh, the more you can carry in your backpack. Still, that isn’t to say you should overfill your bag. Try to carry only what you need to get through the day!
What Should I Look for When Buying a Backpack?
You should do your homework before buying a backpack. There are a ton of options out there, and it’s important to find one that will last you for a long time.
Pay attention to:
Backpacks are often another part of your outfit. With that in mind, you should choose one that looks good and works with your personal style.
Your backpack should hold at least 10 pounds comfortably. It’s important that you find one that’s made from a durable material like cotton canvas, leather, or cordura.
Make sure the backpack you choose is lightweight and easy to carry. Ultimately, the straps shouldn’t feel tight on your shoulders, and your back shouldn’t hurt after carrying the bag around all day.
Number of pockets
A good backpack will have convenient zippered pockets. This makes it easier for you to find what you need without having to dig around at the bottom of the bag.
Who wants to worry about their backpack getting damaged? The best bags are waterproof and won’t be discolored by the sun.
It’s important that the backpack works within your budget. If it comes down to a few extra dollars for a higher quality, don’t be shy about spending. After all, you’re going to use your backpack all the time!
The Bottom Line
Whether it’s made from waterproof nylon, stylish leather, or classic canvas, a backpack is an awesome bag to have in your wardrobe. You’ll use it for school, work, the gym, and epic hiking adventures. Take some time to look for one that’s right for you!
