Buyer’s Guide

Choosing a waterproof backpack can be tough because there are some out there that claim to be waterproof when they are really only ‘water-resistant’ or ‘water-repellent’. This Buyer’s Guide will aim to help you simplify your selection by focusing on three important considerations when buying a waterproof backpack.

Intended Use

This is the number one factor when it comes to buying any backpack. What are the primary activities you plan to use it for? Whitewater rafting, for example, most certainly requires a more durable waterproof backpack than a few hours of paddle boarding on a perfectly calm lake or river.

Additionally, if you’re going to use your waterproof backpack for travel purposes, think about whether it might be beneficial to have any anti-theft devices included. Hidden pockets or a locking main compartment will come in handy when traveling on public transportation in busy, foreign cities.

Durability

Some waterproof backpacks are designed for urban environments in which rain can be frequent and sometimes heavy, but the likelihood of encountering sharp objects is minimal. In this case, an incredibly thick and durable backpack might not be necessary.

However, when you begin to take your waterproof backpack down thundering rapids, through breaking surf, up steep mountain pitches, and around sharp fishing hooks, you’re going to need a pack that withstands the rigors of your adventures. When choosing a waterproof backpack, you won’t go wrong paying a little more for a pack that you know will last for years.

Types of Waterproofing

There are several classes of waterproofing, ranging from Class 1 to Class 5. Class 1 waterproof backpacks are “water resistant for light rain or light splash applications.” This means that water could permeate the pack during prolonged exposure, heavy top-down watering, submersion, or other forceful water pressure applications.

Class 5 waterproof backpacks are “waterproof and submersible to depths greater than 12 feet.” This means they are suitable for underwater sports and some of their common applications include scuba diving, snorkeling, search and rescue, and white water rafting.

Most likely, you’re searching for a backpack that falls somewhere in the middle to high-end of the waterproofing spectrum. As such, it’s important to be able to distinguish between packs that will truly be “waterproof” and those that only offer “water resistance.”

Frequently Asked Questions

Diving into the technical specifications of backpacks can quickly become confusing. There are many abbreviations, acronyms, and units of measurement that apply to backpacks that aren’t used in our daily lives. This Frequently Asked Questions section will help you learn more about some of the most commonly used terms in backpack construction.

Can you explain denier?

Sure! A “denier” is a unit of measure for the linear mass density of fibers or the mass in grams per 9000 meters of said fiber. When applied to backpacks and put to general use, a higher denier count translates to thicker, more resistant material.

What does ‘PVC’ stand for?

‘PVC’ stands for polyvinyl chloride. In terms of backpacks, it most commonly refers to a waterproof-friendly polyester fabric that is strong and durable.

What is the definition of ‘Class 3 Waterproof’?

A Class 3 waterproof backpack is “waterproof so tight it floats or can handle quick submersions.” That said, it is generally known that Class 3 waterproof products can still be permeated by prolonged submersions, submersions greater than 3 feet in depth, and other high water pressure applications.

What is ‘high frequency welded construction’?

High frequency welded construction is a specific manufacturing process that is also sometimes known as dielectric sealing. This process uses electromagnetic energy and pressure to weld and permanently bond thermoplastic, vinyl, and coated fabrics to create a dimensional product.

What is ‘tarpaulin’ and why is it used in so many of these packs?

‘Tarpaulin’ is defined as “heavy-duty waterproof cloth, originally of tarred canvas.” Traditional tarps were actually made of canvas, which is not 100% waterproof. However, modern tarps come in two varieties: polyvinyl chloride (PVC) tarpaulin and polyethylene tarpaulin (also known as “polytarp”). Both of these materials are waterproof, abrasion-resistant, and resistant to oils, acids, greases, and mildew. All of this makes them great fabrics to be used in waterproof backpacks.

Why is the ‘roll-top closure’ so popular?

Oh, you noticed?! The roll-top closure is one of the most common ways to secure items in a waterproof backpack. It has a number of benefits, including eliminating the number of zippers, reducing the number of straps, offering a wider range of use, providing a larger top opening, enhancing top compression, and reducing manufacturing expenses.

What is the proper way to seal a waterproof backpack?

For most of the packs above, you’ll be working with a roll-top closure. Generally, the best method for sealing these packs will be to roll the top at least three times before securing the buckles or straps. However, each backpack is different and you should be sure to consult the pack’s original manufacturer for detailed instructions on how to seal the pack properly.
