Make your backpack waterproof: 3 practical tips

If you travel a lot with your backpack, it is unfortunately not always possible to avoid getting caught in a heavy rain shower.

This can happen on hikes, bike tours, but also simply on the way to school or work.

If your backpack is not waterproof, there is a risk that water will get into the backpack and your items will get wet or even be damaged.

To avoid this, you should make your backpack waterproof . In this article we will discuss the possibilities for this.

Rain cover for the backpack

By far the best and quickest way to waterproof a backpack is to use a backpack rain cover.

Such a cover keeps the backpack and its contents dry and is also easy to use.

To do this, the waterproof rain cover is simply slipped over the backpack and fastened properly. Here it is important to pay attention to robust and tear-resistant material so that holes or tears do not appear so quickly if you get caught on a branch or ledge.

Good rain covers also have reflectors on the outside so that you can be seen well in the dark. You can also use backpack lighting .

Some backpacks are already sold with such a rain cover. If this is not the case with your backpack, then you can simply buy such a cover for little money. All you have to do is make sure you choose the right size for your backpack.

A cheap alternative to rain covers are robust and waterproof garbage bags, in which you can pack your backpack. However, you should make sure to fasten the garbage bags properly so that they do not fall victim to the first gust of wind.

Use waterproof packing bags

To protect the contents of your backpack from water and moisture, you can pack all items in waterproof packing bags. Even if water gets into your backpack, your things stay dry.

Such packing bags are available in different sizes, so that you can pack documents (ID cards), electronics (smartphones etc.), hygiene items, medicines, shoes, individual items of clothing and much more in them.

Even if you transport a laptop in a backpack , you can pack it in it.

Sets that come with several bags in different sizes are practical.

Such waterproof packing bags do not make your backpack waterproof, but they protect the contents from moisture.

To be on the safe side, you can use a stuff sack in combination with a rain cover. Then nothing should really happen.

Waterproof backpack

Another option is to impregnate the backpack with a special waterproofing spray. A good waterproofing spray for backpacks is this one here at Amazon* , which can be used for textiles, leather, high-tech fabrics and synthetics with membrane fibers.

To impregnate the backpack with such a spray, you should first clean it thoroughly and check for any cracks or other damage. The backpack must be dry for waterproofing.

Then stuff the backpack with newspaper so that it is nice and plump and doesn’t crease. This way you make sure that all areas are reached with the spray.

For the actual impregnation, you should go outside in the fresh air, as the spray can irritate the respiratory tract.

Then spray the entire backpack evenly from a distance of about 30 centimeters and let it dry properly. In particular, make sure to treat all seams carefully with the spray, as seams are usually an entry point for moisture.

You can then check whether the impregnation is sufficient by letting some water run onto the surface of the material. If the water rolls off without penetrating the material, the impregnation was successful. If not, the process should be repeated

Before impregnating, however, be sure to read the instructions for the spray, as there are actually different procedures. For example, some impregnation sprays have to work for a longer time than others.

However, it is important to note that waterproofing sprays protect the backpack well from moisture and dirt, but usually cannot make it 100% waterproof.

The impregnated backpack should withstand a small rain shower without any problems, but a tour lasting several hours in heavy rain could still be problematic.

Here it is simply a matter of trying out whether the impregnation is sufficient for your purposes.
