What You Should Know About Waterproof Backpacks?

Waterproof backpacks are the main ally of those who like to travel or practice outdoor activities. If you don’t want to see your belongings get damaged by a sudden rain in the middle of the forest, buying a waterproof backpack seems like the logical choice. Next, we are going to review everything you need to know about this valuable equipment.

Waterproof, water proof, and watertight backpack: what difference does it make?

Although these three types of backpacks preserve our belongings from water and moisture, each offers a different level of protection. The difference lies in the amount of water and humidity that the backpack fabric can repel in a certain period and under certain conditions.

Waterproof backpacks are those prepared to withstand rain or intense showers of short duration.

They can also keep the interior dry if we accidentally drop them in the water. On the other hand, if they are in contact with it for a long time, it could enter its interior. The water-resistant pads are built to withstand light rain.

In no case, they guarantee that the objects we carry inside remain dry in the event of heavy rain or accidental fall into a stream. The waterproof bags offer total protection against water and are even prepared to submerge them completely.

Advantages of waterproof backpacks

Protection against water and humidity is perhaps the most apparent advantage of this type of backpack. However, these articles offer athletes, travelers, and nature lovers a whole series of benefits that should be remembered.

Due to the quality of their materials, fewer dirt sticks to waterproof backpacks than, for example, those made of canvas. Besides, they are easier to clean thanks to the water-repellent treatment of the fabric.

Due to the material’s thickness, the waterproof backpacks offer more excellent protection against theft and accidental breakage.

Waterproof backpacks are generally more durable than a regular backpack. The thick nylon fabric, double stitching, and zippers with rain protection significantly increase this type of backpack’s durability and resistance.

There are many models capable of meeting the needs of a wide range of users: athletes, walkers, motorcyclists, or backpackers.

Like conventional backpacks, raincoats are available in many sizes, from those designed for children, of just ten liters, to those for hikers and climbers, high-end equipment of up to eighty liters.

What are the essential parts of a waterproof backpack?

Every waterproof backpack should have a series of essential elements. Next, we show you which are the most important when determining the quality of the equipment.

  • Handle: Every backpack must incorporate a handle to hold it. This must be comfortable as well as resistant, capable of supporting the weight of the loaded backpack.
  • Zippers: These are the weak point of any waterproof backpack, since through them if they are not sufficiently protected, the water will seep little by little.
  • Adjustable height: Any quality backpack must offer the possibility of adjusting in size. In this way, you can adjust the height at which the backpack is relative to your back, which will mean greater comfort and less fatigue.
  • Adjustable straps: The backpack must have a belt at the waist or chest. In this way, the bag will be adjusted appropriately, and we will avoid discomfort.
  • Padded: Certain parts of the backpack, such as the back, waist, or shoulder straps, must be padded. Thanks to this, we will minimize the discomfort derived from prolonged use, as in long walks.
  • Breathable back: The part of the backpack in contact with our back must be made of breathable mesh fabric. This way, we will avoid excessive sweating.

What are waterproof backpacks made?

Waterproof backpacks are usually made of fabrics such as nylon or polyester, materials with a water-repellent treatment. They typically have double seams, which prevent water from entering their interior for a while. Heat-sealed and welded seams are the most effective and are those that we can find in 100% watertight bags.

Another widely used material in the manufacture of waterproof backpacks is Oxford cloth. This fabric is a variety of polyester, only thicker. Oxford 600D fabric is the most widely used in the manufacture of waterproof suitcases and backpacks. The higher the value of D —denier—, the thicker and stronger the material will be.

What are backpack covers?

Backpack covers are protectors that fit over them to protect them from the rain. They come in a variety of sizes and can do a wide range of backpacks. They are suitable to protect bags that are not waterproof and provide extra protection to those that are. These waterproof protectors are designed to protect the backpack both from light, short-term rains, and from persistent downpours, depending on their quality. They also preserve the gear from dirt and mud, preventing it from getting dirty when placed on the ground. On the other hand, they will not serve as protection if the bag comes into prolonged contact with water.

How to properly use a waterproof backpack?

Like any other type of backpack, waterproof backpacks put the weight of our belongings on our shoulders. Therefore, it is necessary to follow individual recommendations to avoid possible injuries. First, be sure to adjust the straps so that the back of the bag is as close to your back as possible. Waterproof backpacks have a belt on the chest or waist for a better adjustment to our end: use them, as they are there to distribute the weight better and that our shoulders do not suffer too much. Of course, forget that bad habit of carrying it on only one shoulder, as the weight could throw you off balance while walking on uneven terrain.

In the little ones, you must take special care that they do not carry too much weight in their backpacks and that the objects are well distributed. Generally, it is considered that the load should not exceed 10% of the child’s weight. Make sure that your backpack is of quality, with padded straps and enough width to not damage the shoulders.

How to take care of our waterproof backpack?

The water-repellent properties of most sports and travel backpacks are due to the waterproof treatment of the fabric they are made. To extend its useful life, we must take great care to clean and maintain it, taking special care, of course, not to damage its waterproofing layer. Waterproof backpacks can become impregnated with dirt and foul odors, which we must remove by washing them frequently. It is not highly recommended that you wash your bag in the machine, as the straps and zippers could get caught in the holes in the drum, damaging the backpack and even damaging the washing machine.

  • To wash them by hand, immerse the backpack in the bathtub with warm water and a little neutral detergent.
  • Use a dish towel, sponge, or soft brush to remove dirt, both inside and out.
  • After rinsing, hang it upside down to dry, but never in direct sunlight.

Waterproof Backpack Purchase Criteria

Whether you plan to purchase a waterproof backpack or a waterproof bag to practice water activities, you must ask yourself a series of basic questions. The type of use that you will give your backpack and the degree of waterproofing are some of those critical factors, but there are a few more that should be borne in mind.

  • Use that we will give to our backpack
  • Degree of waterproofing
  • Capacity
  • Compartments
  • Comfort
  • Resistant and quality materials
  • Color
  • Value for money

Use that we will give to our backpack.

The use to which we will assign the waterproof backpack is, perhaps, the most crucial factor that you have to take into account when choosing one. For example, it is not the same, a backpack designed for sporadic use as another to which we plan to jog a lot. Neither the design, nor the quality of its materials, nor the level of waterproofing will be the same.

Degree of waterproofing

The level of resistance to the backpack’s humidity is directly related to the use that we are going to give it. If you are one of those who enjoy traveling with a backpack, consider purchasing a quality one. The level of protection against water is proportional to the backpack price, but it is worth paying a little more to keep your things dry.

If you are going to practice water activities, consider purchasing a waterproof bag.

These keep their interior dry even if they remain in contact with water for long periods. Some snorkelers even use them as buoys to mark their position. Dry bags tend to have a smaller capacity than backpacks.


When purchasing a waterproof backpack, you should not be short on capacity. For light and short-term activities, such as trekking or cycling, it is advisable to choose one with between 15 and 20 liters of capacity. If you plan to take it on a trip or camping, you should buy one with a capacity of at least 30 liters.

The size of the backpack should also be based on your height. You must choose a model adjusted to your proportions without going too far or falling short. The backpack you choose must also be adapted to the shape and size of the objects you intend to pack. Hence, there are bags specially designed to transport laptops or photographic equipment.


The quantity and distribution of the compartments are another of the key characteristics when choosing a waterproof backpack. Having your belongings organized and at hand is essential when we go on a trip or practice any nature activity. Some models include an inner waterproof bag to keep wet clothes separate from other objects.

Individual waterproof backpacks are equipped with hooks to hang various objects, such as bags, bottles, or sleeping bags. 100% watertight bags, on the other hand, don’t usually have too many compartments. They are generally tubular, with the main compartment and one or two small-capacity outer pockets.


Comfort is another determining factor when choosing our backpack. Remember that, in most cases, you are going to wear it for many hours, so you should make sure that the straps are wide and padded. In this way, you will avoid discomfort in the shoulders and, in the worst case, any injury.

To distribute the weight better, most models have straps that adjust to the chest and waist. This ensures that the backpack is well fixed to the back and the load balanced. Note that it has a breathable back, preventing prolonged contact with our body from causing excessive sweating.

Resistant and quality materials

The quality of the materials of a waterproof backpack is crucial to avoid unpleasant surprises. It is a factor that usually leads to a higher outlay, an expense; however, that is worth assuming. Make sure the seams are resistant, both on the bag’s body and on the straps and handles.

Also, make sure that the zippers are well protected.

The ideal is to buy a backpack made of quality materials, such as nylon, with several layers capable of keeping the interior dry. The fabric used for ship sails – Dacron – is used by some backpack manufacturers. It is a very resistant and highly waterproof material, which only high-end backpacks incorporate.


Aesthetics is another critical factor when choosing our waterproof backpack. If you are looking to break the monotony of black or gray, there are many models of brightly colored and cheerful backpacks. The watertight bags are usually made in bright colors, such as red, orange, or yellow because they are sometimes used as buoys in diving.

In hot climates, it is desirable to choose light-colored backpacks. In this way, they will better reflect solar radiation and keep our belongings cooler, something vital in electronic devices or food. The bright colors are suitable for forest and mountain activities since they make it easy to distance.

Value for money

The available budget will determine the type of backpack you choose. However, in the market, you can find good quality waterproof backpacks at attractive prices.

Good hiking or cycling backpack does not usually go below € 30, while a camping backpack can cost around € 50.

The watertight bags are more affordable and, although some reach € 60, the usual thing is that most are around € 15 or 20. Waterproof covers are also very inexpensive. Most usually cost between € 5 and € 10, some even less. They are a good option for those who do not need a waterproof backpack but still want to be prepared in the rain.


Those who do outdoor activities or travel with a backpack on their shoulders know the importance of having a waterproof backpack. There are three types: those that repel moisture, the waterproof, and the watertight. To a large extent, our choice will depend on the use that we are going to give our backpack.

Knowing how to choose a waterproof backpack suitable for our needs is vital to safeguard our belongings from moisture. In this article, we have tried to clarify the doubts that these bags raise, such as what materials they are made of, how to use them properly, or their correct cleaning.
