Storing your valuables whilst you are out on the boat, kayak or surfboard should always be inside a waterproof dry bag.

Failure to do so may lead to money becoming damp or electronic devices breaking due to the wet environment.

The best dry bag is the KastKing Roll Top with a range of colors and sizes to choose from with heavy-duty 500D PVC material to keep your belongings safe.

A dry bag is used by fishermen and people in water sports to keep personal items dry and protected from water. They are usually made from a strong and thick Polymer material that is completely watertight.

The closure of the bag is the first point of access for water to enter the bag. The two main types of closures on bags are Hypalon roll-top and zipper seal.

The hypalon roll top simply rolls to form a watertight block, which is then the connection from either side using buckles.

The zipper is fairly obvious, but you basically push the two sides of the bag together to form a seal.

It’s advised to provide lubrication to keep seal forming a strong connection.

The market for waterproof dry bags is highly saturated with many competitors bringing quirky features to compete.

Below is a researched list of the best dry bags for wet activities that ensure your personal items are kept dry.


Definitely a must-have for any time you are on the water, the Marchway waterproof dry bags are designed to protect the valuables that you need to take along when you are on an adventure.

The Marchway will keep your important items dry, clean, safe, and protected from sand, dust, mud, and snow. 

Be sure to take the waterproof bag along when you are out on your kayak or canoe, or when you are snowboarding, skiing, hiking, camping or backpacking.

It is waterproof, lightweight, and compact. The Marchway comes in five sizes and twenty different colors.

Made from thick quality 500D tarpaulin which is an ultra-tough waterproof fabric. The fabric resists tearing punctures and abrasions.

When you put your gear in the dry bag, grab the top woven tape and roll it down tightly three to five times.

Then plug the buckle to complete the seal. This will make the dry bag able to float on the water, so in case it accidentally falls overboard, you will be able to find it. 

The Marchway comes with a detachable and adjustable shoulder strap so that you can carry the dry bag easily.

Earth Pak Roll Top Dry Bag

Roll Top Dry Bag.

Similar to the Adventure Lion, the Earth Pak Drybag comes in three different colors and four different sizes.

Although it is slightly cheaper, it performs just as well and comes with a waterproof smartphone case to add to the package.

The size of the dry bag you choose is completely up to you but I always advise you to go for the largest as you get more bang for your buck.

The 30L and 40L sized dry bags come with backpack straps that provide adequate padding for the long journeys.

Like with other dry bags, the Earth Pak will float on top of the water to prevent water from entering from it being submerged for long periods of time.

Made from a thick 500D PVC material, this dry bag provides great protection from sharp objects.

It is also smooth as well as durable, which means it can also be used as a pillow if you wanted it to be.

Overall this bag is a cheaper alternative to the Adventure Lion with very similar benefits.

One thing I must say is that it doesn’t look as stylish compared with the other bag which has a standout logo printed on the bag.

Unigear Waterproof Floating Dry Bag

Waterproof Floating Dry Bag

Unigear offers the largest range of colors for their dry bags as well as sizes from 5 to 40 liters.

When buying a Unigear dry bag, the 20 liters and above come with two straps as opposed to one, which I strongly recommend.

With all sizes, the straps are well padded to reduce stress on the shoulders.

The tough nylon structure of the Unigear bag provides good all-round protection from sharp punctures.

The closure is in the form of a roll-down, which comes with an added burst resistance and is the best waterproof seal for a bag.

Unigear also offers a waterproof floating smartphone case for added protection whilst inside the bag.

Overall, the bag is solid, waterproof, available in plenty of colors and is reasonably priced.

This dry bag is rated globally and would be the only dry bag you need.

Best Way to Test a Bag is Waterproof Inside

It is all well and good the manufacturers claiming their bags are waterproof, but put them to the test.

The way our team tested the bags was by filling the kitchen sink with water and then place tissue paper inside.

Then it was simply the case of submerging the bag underwater for a few minutes. Its safe to say that all these bags will pass this test with their closure seals shut properly.

What is the Best Dry Bag?

All of the dry bags are great value for money within this article but two, in particular, stand out.

If you are after a larger bag i.e. 30 liters or large, then the KastKing dry bag with the transparent plastic at the front is excellent.

The ability just to look at the dry bag to determine that you have a item is much more convenient than emptying the bag to find the item.

If you are looking for a smaller bag, the Adventure Lion dry bag wins that battle.

The stylish design of the bag with a variety of colors as well as the durability is hard to beat in the small waterproof bag competition.

The one point that was highlighted is the issue with the straps not having enough padding.

However, the smaller dry bags won’t have as much weight and therefore this will not be an issue.
