Backpacks for Scuba Diving: Water Resistance and Durability


  1. Scuba diving is an exciting and adventurous activity that involves exploring the depths of the sea. However, it requires special equipment that is designed to withstand the harsh underwater environment. One of the most important pieces of equipment that scuba divers need is a backpack.
  2. Choosing the right backpack is essential for a comfortable and successful dive. A backpack that is not suitable for scuba diving can cause discomfort and even lead to equipment damage.
  3. The purpose of this article is to provide an in-depth guide on backpacks for scuba diving, with a focus on water resistance and durability. We will discuss the importance of water resistance and durability in scuba diving backpacks, the different types of water-resistant backpacks, factors affecting durability, tips for maintaining durability, factors to consider when choosing a backpack for scuba diving, popular brands and models, and the pros and cons of each brand/model.

Water resistance:

  1. Water resistance refers to a backpack’s ability to keep its contents dry when exposed to water. In scuba diving, backpacks need to be water-resistant to protect the equipment inside from water damage.
  2. Water resistance is important in scuba diving backpacks because scuba divers need to carry expensive equipment such as cameras, regulators, and dive computers. These items can be damaged by exposure to water, so it is important to have a backpack that can protect them.
  3. There are three types of water-resistant backpacks for scuba diving: dry bags, semi-dry bags, and water-resistant backpacks.

Dry bags are made of waterproof materials that seal shut with a roll-top closure. They are the most water-resistant type of backpack and are suitable for carrying items that must stay dry at all times. However, they are not as easy to access as other types of backpacks, and they can be less comfortable to wear.

Semi-dry bags are made of water-resistant materials that offer some protection against water. They have a zippered closure that is covered by a flap, which helps keep water out. They are easier to access than dry bags but not as water-resistant.

Water-resistant backpacks are made of materials that repel water but are not completely waterproof. They are suitable for carrying items that are not as sensitive to water damage as cameras or dive computers. They are the most comfortable type of backpack to wear and the easiest to access.

The advantages and disadvantages of each type of water-resistant backpack depend on the needs of the scuba diver. Dry bags are the most water-resistant but are less comfortable and less accessible than other types of backpacks. Semi-dry bags offer a good compromise between water resistance and accessibility, but they are not as water-resistant as dry bags. Water-resistant backpacks are the most comfortable and accessible, but they offer the least amount of water resistance.

III. Durability

Durability is an important aspect to consider when choosing a backpack for scuba diving. Durability refers to the ability of a backpack to withstand wear and tear, exposure to the elements, and impact. A durable backpack is one that can withstand rough handling, repeated use, and exposure to saltwater and UV radiation without falling apart or losing its shape.

Importance of Durability in Scuba Diving Backpacks

Durability is essential for scuba diving backpacks as they need to withstand the harsh marine environment. Scuba diving backpacks are constantly exposed to saltwater, UV radiation, and abrasion from rocks and sand. They need to be sturdy enough to withstand these elements while providing adequate protection to the diving equipment. A durable backpack also ensures that the diver’s gear stays in place during transportation, preventing damage or loss.

Factors Affecting Durability

There are several factors that affect the durability of a scuba diving backpack. These include the materials used, stitching, and zippers.


The choice of materials plays a significant role in determining the durability of a backpack. Materials that are resistant to wear and tear and can withstand exposure to saltwater and UV radiation are preferred for scuba diving backpacks. Common materials used in backpacks for scuba diving include nylon, polyester, and PVC. Nylon is a popular choice as it is durable, lightweight, and resistant to abrasion. PVC is another popular material as it is waterproof and easy to clean. However, it may not be as durable as nylon or polyester.


The stitching used in a backpack can significantly affect its durability. Poor quality stitching can easily unravel, especially when exposed to saltwater and UV radiation. High-quality backpacks for scuba diving use reinforced stitching that can withstand the wear and tear of regular use.

Zippers and Other Closures

Zippers and other closures are also crucial components that can affect the durability of a backpack. Cheap, low-quality zippers can easily break or become corroded when exposed to saltwater. High-quality backpacks for scuba diving use corrosion-resistant zippers and closures that can withstand exposure to saltwater and UV radiation.

Tips for Maintaining Durability

Proper maintenance is crucial for ensuring the durability of a backpack for scuba diving. Some tips for maintaining the durability of a backpack include:

  1. Rinse the backpack thoroughly with fresh water after each use to remove saltwater and debris.
  2. Dry the backpack in a shaded area and avoid exposing it to direct sunlight, which can cause fading and damage.
  3. Store the backpack in a cool, dry place to prevent mildew and mold growth.
  4. Use a protective spray or wax to enhance the water resistance and durability of the backpack.
  5. Choosing the Right Backpack

Type of Diving

The type of diving you plan to do can affect the type of backpack you choose. If you plan to do shore dives, you may need a backpack that is more durable and abrasion-resistant. If you plan to do boat dives, you may need a backpack that is more water-resistant and lightweight.

Frequency of Use

If you plan to use the backpack frequently, you may want to invest in a more durable and high-quality backpack. If you plan to use it infrequently, you may opt for a more budget-friendly option.

Storage Capacity

Consider the amount of gear you need to carry and choose a backpack with sufficient storage capacity. Look for a backpack with multiple compartments and pockets for easy organization.

In conclusion, choosing the right backpack for scuba diving is crucial to ensure a safe and enjoyable diving experience. Water resistance and durability are two key factors to consider when selecting a backpack. Water-resistant backpacks come in different types such as dry bags, semi-dry bags, and water-resistant backpacks, each with its own advantages and disadvantages. Durability, on the other hand, depends on the materials used, the quality of stitching, and the type of closures. Maintaining the backpack properly can prolong its lifespan and ensure its reliability during dives.

When choosing a backpack for scuba diving, there are several factors to consider such as the type of diving, frequency of use, storage capacity, comfort and fit, and budget. Popular brands and models such as Cressi Gorilla Pro, Mares Cruise Backpack Pro, and Aqua Lung Defense Pack are good options to consider, each with its own pros and cons.

In terms of final thoughts and recommendations, it is important to prioritize functionality and durability over aesthetics when choosing a backpack for scuba diving. Additionally, it is essential to properly maintain and store the backpack to ensure its longevity. It is also recommended to invest in a quality backpack to ensure its reliability during dives.

As a call to action, scuba divers should research and carefully consider their options before purchasing a backpack for scuba diving. They should also prioritize their safety and comfort during dives by selecting a backpack that meets their specific needs and preferences. By doing so, scuba divers can enjoy their diving experiences to the fullest while keeping themselves safe and prepared.
