7 Best Waterproof Swim Bags (And why you need one)


Waterproof swim bags are essential for outdoor swimmers. They are a great way to keep your gear dry, while also acting as a tow-float as you swim outdoors.

The difference between waterproof swim bags, specifically for swimming, and regular dry bags is that waterproof swim bags will be inflatable, giving you extra buoyancy as you swim in the water.

I have found that regular dry bags are a great option for keeping your clothes and valuables dry on land. However, swimming with a regular dry bag is a bad idea. If any water gets inside an ordinary dry bag while underwater, the contents within will become waterlogged and could sink.

After careful consideration, I have realised that the majority of dry bags are not made to be submerged or remain in the water for extended periods of time.

If you accidentally drop a dry bag into the water, it will temporarily float and protect your items as long as you grab it quickly and get it out.

This is great for kayakers or water sports enthusiasts who are on or near the water, but this is not helpful for swimmers who are in the water.

Waterproof swim bags on the other hand can store your gear, just like a dry bay. However, they have the option to be inflated, thus giving more buoyancy.

In addition, many swim bags double up as a tow float, in the event that you need something to hold onto in the water for some extra buoyancy. It should be noted that waterproof swim bags are not safety devices and your bag should not be relied upon as a life-saving device.

Below is a picture of my waterproof swim bag (on the left) and my dry bag (on the right) so you can see how a waterproof swim bag differs from a regular dry bag.

Waterproof Swim Bags – Frequently Asked Questions

The following is a list of the most commonly asked questions about waterproof swim bags.

Can You Swim With A Waterproof Bag?

Swimming with a waterproof bag is possible, and it can be a great way to keep your belongings safe while you take a dip.

Waterproof swim bags are designed to keep items dry and add some buoyancy so the bag does not sink.

They come in many different styles, materials and sizes, so you can find one that fits your needs.

Many of these bags feature a roll-top closure or other waterproofing technology that prevents water from getting inside. They also usually have adjustable straps, so you can carry them comfortably on your back or over your shoulder.

What Is The Difference Between Water Resistant And Waterproof Bag?

Waterproof bags are made of materials that completely prevent water from getting inside, while water-resistant bags will only provide some protection against moisture.

Waterproof bags are usually constructed with a PVC coating or a laminate material layer that creates an airtight seal when closed, ensuring all the contents remain dry and protected.

Water-resistant bags, on the other hand, are often made of a material that is resistant to water but not completely waterproof.

What Is The Difference Between A Dry Bag And A Waterproof Bag?

A dry bag is designed to keep the contents inside dry, but not necessarily waterproof.

A waterproof bag is designed to keep water out, protecting the contents from getting wet even if submerged or exposed to heavy rain.

While both are useful for carrying items in wet environments if you want your items to stay completely dry while swimming, a waterproof bag is your best bet.

Swimming waterproof bags will have the option to inflate the bag, so your contents can float behind you in the bag as you swim.

Do Waterproof Bags Float?

Waterproof swim bags are specifically designed to keep your items dry and protected, even if they’re submerged in water for extended periods of time.

Generally speaking, these bags are made from durable PVC which prevents the bag from becoming saturated and keeps water out.

Swim bags with an inflatable airbag are designed to float. Some waterproof swim bags have two separate airbag compartments to for extra protection in case one airbag compartment gets punctured.

It is best to check with the manufacturer of your chosen swim bag to ensure that it is designed to float.
