Buy a 20L waterproof backpack: How to make the right decision?
We all encounter rain in our daily life or on our hikes. We cannot control it. But with a 20L waterproof backpack, you’ll never have to worry again.
Waterproof backpacks are real everyday heroes:
- The contents are protected from humidity.
- The material is generally of very high quality and durable.
- There are some beautiful designs.
- Many manufacturers cater to outdoor enthusiasts and produce with respect for the environment.
I show you how to recognize a sturdy and waterproof backpack. So you can quickly find out who can become your hero daily!
What Should You Consider When Buying A 20L Waterproof Backpack?
In your search for the best 20L waterproof backpack, you should pay attention to the following features:
- Difference between waterproof and waterproof
- Wearing comfort
- Size and distribution
- Intended use
Difference between waterproof and water repellent?
Waterproof means the backpack can withstand heavy rain or continuous rain. Water repellent means that the water will not drain off after a long time and cannot resist a lot of water. In this case, the material is only waterproof or water repellent.
I advise you to do the following test before using your 20-liter waterproof backpack:
- Place a roll of toilet paper inside the backpack.
- Pour a bucket of water over the backpack.
- If the toilet paper roll stays dry inside, the test is successful!
- Waterproof backpack materials.
Most manufacturers use:
- tear-resistant nylon fabric
- plastic or PVC
Backpacks made of impregnated fabric are usually only waterproof, but not waterproof. The 20 L backpacks in my review are entirely waterproof, so you can buy them in complete safety.
Your backpack needs an opening to fill it. But it is still a weak point for water. The safest solution is, therefore, a roll closure. It is also called roll-top closure.
With a roll-top, the opening is hidden under several layers of waterproof fabric when rolled up. The seams also represent tiny openings. To indeed resist water, the seams of the backpack must be taped.
What a lot of people don’t know about waterproof backpacks:
If not, the manufacturer can only write “waterproof” on their product.
Comfort is an absolute must. This is the only way to enjoy carrying the backpack for a long time.
The best wearing comfort:
Padded shoulder straps are ideal. The wider the straps, the better they distribute the weight. For heavy luggage when hiking, the backpack should be equipped with chest and hip straps. This allows you to spread the weight over as much area as possible.
Backpack size and layout
The size of the backpack is a matter of need. The hikes require more space than the daily trip to the university, for example:
10 – 20 liters: A volume between 10 and 20 liters is sufficient for a laptop, files, etc.
30 – 60 liters: for treks, you should use backpacks of 30, 40, or even 60 liters.
The distribution of the different compartments also depends on your needs:
- External pockets: for hikes, outer pockets for bottles and hiking equipment are essential.
- Interior Compartments: If you have valuables with you, you should make sure that there is a separate interior compartment.
- Laptop Compartment: If you want to use the backpack on the way to college or work, you should use a waterproof backpack with a laptop compartment.
You can also buy a foldable backpack if you want to be able to use two backpacks but only one waterproof at one time. This will then allow you to store it in the 20 L waterproof backpack.
Intended use of a backpack
Choosing the best waterproof small backpack depends a lot on its use:
- Waterproof: While kayaking, hiking in torrential rain, or on the SUP, the backpack should be waterproof enough to survive a full descent.
- Water repellent: If, on the other hand, you are only looking for adequate protection against medium to heavy rain or splashing water, a highly water-repellent backpack is quite sufficient.
How much does a 20-liter waterproof backpack cost?
Typically, you will find your 20-liter backpack in the price range of € 15 to € 130. However, if you focus on quality and specific features, the price will increase accordingly. A waterproof 20L backpack price also depends on the brand, with some brands in a higher price range. You need to make sure that you are paying for good quality and not just for the brand.
What are the alternatives to a 20L backpack?
The obvious alternative would be a different volume than a 20-liter backpack. Depending on your needs, you may need more than 20L of volume and use a larger backpack.
Of course, the reverse would also be true if your 20-liter backpack is a little too big for your usual excursions or everyday life, and you don’t need the space. In this case, a smaller version would suit you better.
Tips for maintaining your waterproof backpack
Why are lightweight waterproof backpacks not allowed in the washing machine?
To keep the material waterproof, it is often coated, and the seams are welded. This coating can come off under the strong influence of detergent, towers, and heat in machines. The backpack may then leak.
The 20 L waterproof backpacks are therefore only cleaned by hand:
- Use a mild soap mixed with baking soda (1 tbsp for disinfection).
- Mix everything with hot water in a bucket.
- Rub the backpack with the mixture and a rag.
- Leave to dry on the clothesline.
- If necessary, you should also use a disinfectant for spraying.
- Warning: Never wash your waterproof backpack in the washing machine. They are also not suitable for tumble dryers.
