Table of Contents

What is a waterproof bag?

If you are running an outdoor brand around water sports products or a business dealing with goods that require protection from water or moisture, or if you are simply an outdoor enthusiast, waterproof bags might be what you need. Waterproof bags are specially designed bags that offer protection from water, dust, sand, or dirt. They are ideal for activities such as boating, camping, hiking, and outdoor work that involves exposure to elements.

Waterproof bags are usually made of durable, waterproof materials like polyester, nylon, or oxford, with layers of coating like PVC or TPU, and feature roll-top closures or watertight zippers to prevent water from seeping in.

Types of waterproof bags

Waterproof bags come in different types, including dry bags, waterproof backpacks, waterproof duffel bags, waterproof tote bags, waterproof phone pouches, and waterproof cooler bags.

Dry Bag

Dry Bag

Dry bags are cylindrical bags that are sealed at the top to prevent water and air from entering. They are perfect for activities involving water since they keep the contents dry. Sometimes, they may also be called dry tubes or dry sacks.

Waterproof Backpack

Waterproof Backpack

Waterproof backpacks are backpacks that are lined with waterproof material as well as seamless sealing to make them suitable for activities in wet conditions. They have various compartments and pockets for organization. However, their costs are often higher than dry bags.

Waterproof Duffel Bag

Waterproof Duffel Bag

Waterproof duffel bags are spacious and suitable for carrying heavy and bulky items. They feature handles or shoulder straps to make them comfortable to carry. However, they can be more cumbersome to carry compared to backpacks, and may not be suitable for long hikes.

Waterproof Tote Bag

Waterproof Tote Bag

Waterproof tote bags are versatile, and ideal for carrying groceries or beach items. They can be stylish and fashionable, yet their limited storage capacity makes them unsuitable for carrying heavy items.

Waterproof Phone Pouch

Phone Pouch

Waterproof phone pouches are specialized for phones and provide excellent protection for phones against water damage while allowing for phone functionality via the touch screens. They are cheap, easy to use, and can be worn around the neck or carried.

Waterproof Cooler Bag

Waterproof Cooler Bag

Waterproof cooler bags are for those who need to have their food and drinks cool or hot for several hours in various outdoor activities and events. They have an extra layer between the fabric and the coating material to keep the temperature inside the bag. They are often more expensive than other types of waterproof bags.

Materials used in waterproof bags

When it comes to waterproof bags, materials play a critical role in determining their resistance to water. In this section, we will compare four commonly used materials in waterproof bags: polyester, nylon, oxford, and RPET.



Polyester is a durable and affordable material used in waterproof bags. It is also lightweight, flexible, and easy to clean, making it one of the most common choice for waterproof bags. Polyester offers excellent resistance to abrasion and UV radiation and can withstand regular use. It is also a popular option for its affordable price point. PVC- or TPU-coated polyester is sometimes referred to as Tarpaulin.


Nylon, on the other hand, offers superior resistance to water and moisture compared to polyester. It is a lightweight material that offers excellent durability and strength. Nylon is highly resistant to tears, punctures, and abrasions, making it a preferred material for rough outdoor conditions. Although nylon is slightly more expensive than polyester, its long-lasting quality makes it a sound investment for frequent outdoor activities.


Oxford fabric is thicker and sturdier than both polyester and nylon. It is highly resistant to tears and abrasions and offers excellent protection from water and moisture. It is also highly breathable, making it ideal for items that require ventilation. However, the heaviness of the material makes it more cumbersome to carry around compared to polyester and nylon. Oxford fabric is also typically more expensive than both polyester and nylon.


RPET (Recycled Polyethylene Terephthalate) is a relatively new material used in waterproof bags. It is made from recycled plastic bottles, making it an environmentally friendly option. RPET offers similar durability and resistance to water as polyester and nylon. It is also lightweight and flexible, making it a practical option for outdoor activities. However, RPET can be slightly more expensive than polyester but less expensive than nylon. In terms of the environment, RPET stands out as a sustainable option, making it an ideal choice for environmentally conscious consumers.

Coatings used in waterproof bags

Coatings are essential in ensuring the effectiveness of waterproof bags. The coating is the layer applied to the outside of the bag to stop water from penetrating the surface. PVC and TPU are the two most common coatings used in waterproof bags.

PVC is extensively used in waterproof bags because it is affordable, lightweight, and flexible. It is also resistant to chemicals, oils, and dirt, making it ideal for outdoor use. However, PVC is not biodegradable, making it harmful to the environment. PVC also tends to deteriorate faster than other coatings, leading to decreased effectiveness over time.

TPU is a more eco-friendly alternative to PVC. It is more resistant to abrasion, water, and chemicals, making it more durable and longer-lasting. TPU is also flexible and lightweight. Unlike PVC, TPU is biodegradable, reducing its environmental impact. It is also a more expensive option than PVC, but for businesses looking to reduce waste and maintain sustainability in their operations, TPU is a worthwhile investment.

Important features to consider

The first feature to be considered for every waterproof bag is the waterproof properties. This is affected by both the material, the coating, and the construction process. And it can be measured in various methods, the most well-known one being the IPX rating system.

For individuals buying waterproof bags, keep an eye out for key features like sealed zippers, roll-top closures, and seamless welding. Shoulder straps should be padded and adjustable for comfort, and some bags even come with removable waist straps for added stability. External pockets can be convenient for quick access to items like snacks, sunscreen, or a water bottle.

For businesses, features such as branding, labeling, and compliance with safety regulations should be considered when selecting a waterproof bag supplier.


A waterproof bag can be a game-changer for outdoor enthusiasts and workers who want to keep their belongings safe and dry. The type of waterproof bag, the material, and the coating are necessary for individuals who want to enjoy peace of mind, as well as businesses who provide waterproof bags to the market.
