How Do I Test If My EDC Backpack Is Waterproof?

Protecting your gear from the elements is crucial for everyday carry, whether heading into the outdoors, traveling, or commuting to work or school. That’s why knowing whether an everyday carry backpack is waterproof is essential. Today, I will walk you through effective and safe methods to test an EDC backpack’s waterproof capabilities, how to improve it (if necessary), and ways to ensure your tech gear stays dry.

Understanding Waterproof vs. Water-Resistant

Before testing your EDC backpack, let’s understand the difference between waterproof and water-resistant so that you can set realistic expectations. 

A waterproof EDC backpack is designed to keep water out of your bag 100%, even when caught in heavy rain or submerged in the water.  Typically, these backpacks are made from nylon with TPU coatings, PVC, or welded seams. 

Meanwhile, water-resistant backpacks can deal with light splashes or brief water exposure. By saying this, they cannot handle prolonged rain exposure or submersion. In short, they aren’t fully sealed against the elements.

Preparation Before Testing

Before testing if your backpack is waterproof, follow these preparatory steps to avoid damaging your gear.

1. Empty your bag. Take out your laptop, notebooks, chargers, valuables, and other EDC backpack items to avoid accidental damage.
2. To detect water intrusion or leaks, use tissue paper, paper towels, or other absorbent materials as test materials.
3. Inspect your bag for holes, damaged seams, loose zippers, and other visible signs of wear, which could compromise the results. 
4. Test in a safe location, like the shower, bathtub, or backyard.

Safe Testing Methods

Now, your backpack is ready for testing. Follow these steps to effectively and safely test whether it is waterproof. 

Simulated outdoor exposure

Leave it outside during light to moderate rain to test it in real-world scenarios.  Check how well it can hold up over at least an hour. 

Light shower test

Put your bag under a garden hose or handheld shower and let water hit it for 10 minutes at all angles. When done, open it to check for moisture in the test materials. 

Submersion test for waterproof backpacks

Only do this for an EDC backpack labeled waterproof. Start by filling a basin, sink, or bathtub. Then, partially submerge your bag, focusing on the zippers and seams. Hold it underwater for a minute before removing it. When done, look for water penetration. 

What to Avoid During Testing

You should take extra precautions when testing your backpack. Check out the following for the mistakes to avoid. 

• Do not fully stuff your EDC backpack; otherwise, the zippers, seams, and materials will be stressed, and it could lead to leaks. 
• Be sure to complete the inspection after testing. Check your bag for signs of water intrusion, like damp fabric or wet spots in its interior.
• Do not use high-pressure jets or hoses when testing your backpack. Otherwise, this might lead to damage. 

Interpreting the Results

Evaluate your bag’s performance after testing its waterproof capabilities.  

• If you didn’t find signs of moisture in the test materials or the inside of your backpack, it passed the test—yes, it’s waterproof!
• If you spot damp areas around the bag’s zippers and seams, you have a water-resistant backpack—meaning it has light rain protection. 
• But if your bag’s interior is soaked, it lacks waterproofing capabilities. This means your backpack cannot meet your waterproofing needs. 

How to Improve Waterproofing

If you want to enhance the water resistance of your EDC backpack, here are some tips for you. 

1. Apply waterproof sealants or sprays. Ensure it’s fabric-safe and compatible with your backpack’s fabric, though. Check the manufacturer’s instructions regarding applying waterproof sprays and sealants. 

• • Spray the zippers, seams, and other exposed fabric.
  • Reapply waterproof coating regularly, as needed, because waterproof sealants and sprays will eventually wear off over time, especially with frequent exposure to harsh weather and heavy use. Reapply such treatment every few months or when you notice that water starts to bead less.

2. Invest in and use a rain cover that fits over your EDC backpack. This is particularly useful for unpredictable weather and extended trips. 
3. Use waterproof packing cubes or dry bags for additional protection. Store your sensitive items in them before putting them in your backpack.  
4. Reinforce the vulnerable areas. Apply zipper wax and seam sealants to prevent water from seeping through zippers and seams
5. If your backpack lacks an internal liner, consider adding a waterproof interior bag or removable liners to prevent water from reaching your sensitive EDC items, such as electronics and other gear.
6. Do not overstuff your backpack, as this may strain the seams and zippers, which are prone to water penetration. Pack within the intended backpack capacity to reduce gaps from forming (this could allow water to penetrate the interior of your bag).

Conclusion

By now, you already know the answer to the question, “How do I test if my EDC backpack is waterproof?” 

Understanding how to test your bag for waterproof qualities properly can ensure your gear stays dry. If your bag is not waterproof for your needs, you can always enhance its waterproof capabilities. Incorporate the strategies we shared earlier to keep your items dry and ensure your bag can withstand unpredictable weather.Alternatively, you can invest in a new waterproof bag with the right EDC backpack size. Choose models with waterproof qualities to ensure your EDC items stay dry—rain or shine. Nevertheless, spending some time testing your bag’s waterproofing ensures you’re always prepared for anything.
