When it comes to motorbike backpacks, one of the most important factors to consider is water resistance. Whether you’re commuting to work or embarking on a long journey, you want to be sure that your belongings are protected from the elements. In this article, we’ll explore the importance of water resistance ratings and testing for motorbike backpacks, so you can make an informed decision when choosing the right gear for your needs.

Water Resistance Ratings

Water resistance ratings are used to indicate how much water a backpack can withstand before it starts to leak. The most common rating system is the Ingress Protection (IP) rating, which is a two-digit number that indicates a product’s resistance to dust and water. The first digit refers to dust resistance, while the second digit refers to water resistance. For example, a backpack with an IP68 rating would be completely dust-tight and able to withstand continuous immersion in water.

When choosing a motorbike backpack, it’s important to look for a high water resistance rating, especially if you plan to ride in rainy or wet conditions. A backpack with a low rating may provide some protection against light rain, but it won’t be suitable for heavy rain or prolonged exposure to moisture. A high rating, on the other hand, will give you peace of mind that your belongings will stay dry even in the worst weather conditions.

Testing for Water Resistance

While water resistance ratings can provide a general indication of a backpack’s ability to repel water, they don’t tell the whole story. In order to be sure that a backpack is truly waterproof, it needs to undergo rigorous testing. The two most common testing methods are the water column test and the spray test.

The water column test involves placing the backpack under a column of water and measuring the height at which water starts to seep through the material. The higher the water column height, the more water-resistant the backpack. A backpack that passes the water column test is considered to be waterproof and able to withstand heavy rain or even immersion in water.

The spray test involves spraying water onto the backpack from different angles and intensities to simulate real-world conditions. The backpack is then inspected to see if any water has penetrated the material. This test is useful for identifying areas of weakness in the backpack, such as seams or zippers, that may need additional sealing or reinforcement.

Choosing the Right Motorbike Backpack

When choosing a motorbike backpack, it’s important to consider your specific needs and usage. If you frequently ride in wet conditions, a backpack with a high water resistance rating and rigorous testing is a must. Look for backpacks with an IP rating of at least 65, which indicates that it’s dust-tight and able to withstand low-pressure water jets from any direction.

Other features to look for in a waterproof motorbike backpack include sealed seams, waterproof zippers, and water-resistant materials such as nylon or polyester. A backpack with multiple compartments and pockets can also help to keep your belongings organized and dry.

It’s also important to consider the size and capacity of the backpack. Make sure it’s large enough to hold all your gear, but not so large that it feels bulky or uncomfortable to wear. Look for backpacks with adjustable straps and a padded back panel for added comfort and support.


Water resistance is a crucial factor to consider when choosing a motorbike backpack. A high water resistance rating and rigorous testing can provide peace of mind that your belongings will stay dry even in the worst weather conditions. When shopping for a waterproof motorbike backpack, look for a high IP rating, sealed seams, waterproof zippers, and water-resistant materials. With the right gear, you can enjoy your ride without worrying about the weather.
