Waterproof Snorkeling Bag Buying Guide


Even though some bags are marketed as being completely waterproof, dry bags are not intended to be submerged underwater for very long. The main purpose of a dry bag is to protect its contents from the occasional splash, rain, snow, or even a brief dip underwater and back out. Under normal use you can expect the waterproofing to keep your belongings dry, however if you submerge it under water for more than a few seconds you should expect some leakage. Check the included instruction manual or read the product description to know how much it is rated to handle.


Generally, dry bags are constructed from Ripstop PVC tarpaulin or heavy-duty vinyl. Vinyl excels at carrying heavy gear as well as keeping water out. In addition, you can also use it for carrying smaller, more personal items. Next, Ripstop PVC tarpaulin is another great alternative for protecting your belongings from water, as well as rain, snow, sand, and the elements.


The most common way to seal a dry bag is with a roll-top closure system and it is very effective at preventing water from entering. This system works by rolling the top down and then securing it with a quick-click buckle. There are other ways dry bags can be closed, such as with a press and seal mechanism or a zipper. However, the roll-top closure is the most popular because of how effective it is.

D-Ring and Straps

Dry bags usually include adjustable or removable straps to give you the option of how you want to carry it. Many dry bags are designed with either one or two straps to allow for more carrying styles. For instance, having only one strap allows for over the shoulder or chest carry. The two-strap designs can be carried like a traditional backpack. Both styles are viable and can be used to carry a lot of weight.

Furthermore, the D-rings can be used for clipping on or off the straps. You can also use them to secure your dry bag on a boat, kayak, or canoe. With the help of D-rings and straps, you have many ways to carry your dry bag when travelling.


If you’re not aware, it is recommended that your dry bag is big enough so that when you put all of your gear inside, it is only ¾ full. Leaving some space available is preferred as a precaution just in case you need to carry more items, otherwise the extra space can be filled with air and make the bag buoyant.

Dry bags range in size, capable of carrying from 5L to 55L in volume. The 5-liter bag is ideal for protecting your small personal items such as cell phone, keys, jewelry, or snacks. You’ll want a significantly bigger bag to carry your gear, clothing, and other snorkeling or scuba gear. Following the ¾ rule above, if you simply have too much gear for one bag then you may need multiple dry bags to protect your belongings.

Bag Construction

How the bag is made will determine its intended use. For instance, many dry bags are constructed using stout seams or fusion-welded seams for more waterproofness. If you intend on bringing a dry bag with you into open water, you need one that has a strong, durable construction. For those looking for a camping bag, it is important to look for a bag that is water and mold-resistant. Check the product description to see how much it can handle.

Types of Dry Bags

There are many dry bag designs on the market. Below, we provide a brief overview of the kinds that are available and what they are intended for. Carefully examine each one to decide which style is the right one for you.

Kayak Dry Bags

If you often make trips out to the water, you need to get yourself a dry bag. Most 5L dry bags can fit in the compartment of a kayak for convenient storage. Whenever a kayak tips, then naturally everything inside will get submerged. If you don’t have a dry bag to protect your valuables, then that will be one of the most expensive dips you’ll take. In rough water, it is recommended to secure the dry bag using D-rings so that you won’t lose them.

PVC Dry Bags

Dry bags made with PVC are extremely durable and long-lasting, capable of enduring the most rough conditions. Thanks to PVC’s natural waterproofing, it is not only the optimal material to construct a dry bag from, but the strength and robustness adds a layer of protection to your belongings. Unfortunately, its toughness is also its downside, as it is much heavier than other dry bags, but that’s the price of protection for you.

Barrel Roll-Top Dry Bags

Yet another popular type of dry bag is the barrel roll-top style which are capable of withstanding any intense water sport activities. Thanks to its cylindrical shape, it is very versatile in where it can fit. Sealing this type of bag is simple; just hold the open ends together, roll it down, and then lock it using the quick-click buckle. This method of closure will ensure water stays out and the contents stay dry.

Lightweight Dry Bags

As with any backpack or carrying case, dry bags also come in various weights. For activities that require you to carry a bag for long periods of time, such as hiking, traveling, or going out into the water, you want a light bag to preserve your stamina. Lighter bags may provide less protection than heavier bags due to the material they are constructed from, however a heavy bag can cut a trip short due to exhaustion.

Backpack Dry Bags

For those looking for a hands-free bag, the backpack style dry bags are what you want. Since backpack dry bags also have the same closure design as barrel roll tops, they are highly similar and the only difference is two straps vs. one.

Electronics Dry Bags and Cases

If you’re prone to dropping or losing things, then you’ll want a specific bag to carry your phone, camera equipment, or other electronics. Since water can ruin your electronic devices, dry bags for electronics must be as waterproof as possible. For example, waterproof cases for phones will not only keep water out but can let you take pictures underwater.

Camera dry bags are also crucial for taking expensive equipment around when it’s raining or there’s water nearby. There are two main styles for electronics dry bags – the roll top dry bag which we’ve already discussed earlier, and a waterproof case. With the waterproof housing, you can take pictures with your camera underwater. Expect to pay a premium for a high-quality dry bag or case for your electronic equipment to ensure you’re buying a quality product that won’t leak.

Frequently Asked Questions

How Do You Clean A Dry Bag?

Any piece of equipment that gets exposed to moisture can lead to mildew growth. Mildew is a fungus that can harm your lungs and must be cleaned immediately. Furthermore, studies have found that prolonged exposure to mildew may lead to allergies, nervous system disorders, or even depression. Thus, you should let your dry bag completely air dry after it is exposed to water to prevent mildew from forming in the first place.

To clean a dry bag, use warm or cold water. Do not use hot water, as it could damage the seams or shrink the material. Scrub with mild, non-detergent soap gently; don’t put it in the washer. For a natural antibacterial soap, mix lemon and salt together and use it on any mildew to get rid of it. Lastly, always air dry your dry bags; putting it in a dryer or washer can damage the waterproofness.

How Do You Seal A Dry Bag?

Your bag won’t be very waterproof if you don’t know how to seal it. Most dry bags have a roll-top design. To seal, first press the lips of the opening together, then roll it down at least three times. The more rolls the tighter the seal, but three should suffice. Then connect the buckle and your dry bag is officially sealed.

This process is not difficult, but you’ll want to practice it a few times on your own. Also, before putting expensive equipment in and taking it with you on a trip, test the limits of your bag at home by splashing water on it and submerging it for a few seconds. Then you’ll have a good idea of how much your dry bag can handle should you decide to take it out.

How Do You Repair a Dry Bag?

No matter how durable a product is, all materials will suffer wear and tear, and even dry bags constructed from vinyl or PVC tarpaulin may eventually tear. If and when this occurs, you may be able to fix it with some DIY repairs. You’ll need to be cautious, since an improper repair will damage the waterproofness of the bag. You can use either adhesive repair patches (B07HSKRYQW) or repair adhesives (B01BNLAZ2W) to help seal any holes. Repair tapes are recommended for large tears, and adhesives for smaller ones.

What are the Benefits of Welded Seams for Dry Bags?

First, welded fabric seams refers to when two pieces of waterproof material are bonded together to form a larger piece of waterproof fabric. Do this enough times and you have yourself a dry bag (we’re simplifying things a bit here). Using an advanced process known as high-frequency welding (HFW), manufacturers are able to make bags with tremendous waterproofing capabilities. It makes the seam as durable as the surrounding material, so you can get an even level of waterproofness and durability across all surface areas of the bag.

What Happens if My Dry Bag Falls Into the Water?

Especially if your bag is full of equipment, will it sink to the bottom of the sea? Thankfully, most dry bags will float. Furthermore, it is recommended that you only pack your dry bags ¾ full and let the remaining ¼ fill with air. This will provide additional buoyancy so that the bag can float.

Can Dry Bags Be Submerged?

Despite the name “dry bags”, they will not keep your belongings dry for very long. Depending on the brand, bags from cheaper brands will have less water resistant material and water may enter immediately. More expensive and reputable brands will have better seam construction and durable materials which can keep water out for a short period of time. However, you should try not to submerge your bag underwater, and if unavoidable, try to bring it to the surface immediately.

How Are Dry Bags Made?

Most dry bags are constructed using PVC ripstop tarpaulin and durable vinyl, both of which are rugged, strong, and waterproof. Pieces of these materials are bonded together using high-frequency welding to create a tough seam that keeps water out. In addition, you may find some dry bags made from nylon which is not as water-resistant. However, they are effective at keeping out dirt, sand, and splashes of water from ruining the contents of the bag.

Can You Swim with A Dry Bag?

It is possible to swim with a dry bag, however you should try to keep it out of the water as best you can. Also, make sure that the seal is tightly closed as this is where water will most likely enter. Furthermore, remember to leave some empty space in the bag for air to fill up to add more buoyancy to the bag, helping it to stay partially out of the water to not weigh you down as much.
