5 Best Waterproof Dry Bags 2018

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 color and sizes to choose from with heavy duty 500D PVC material to keep your belongings safe.

A dry bag is used by fisherman and people into 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 the connected from either side using buckles. The zipper is fair obvious, but you basically push the two side of the bag together to form a seal. Its 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.

Adventure Lion Waterproof Dry Bag


Adventure Lion watertight dry bags are extremely popular throughout the US and is available in 8 different colors and 4 sizes. Using a 7.5mm thick waterproof material, this dry bag is one of the toughest bags on the market that will last a lifetime. I say last a lifetime as they offer a lifetimes warranty, which proves the manufacturers have great confidence in their product.

Thanks to the high frequency bonding used throughout the bag, it is able to withstand anything you chuck at it. The solid roll-top closure ensures a completely watertight bag to provide your personal items with the best protection.

The Adventure Lion provides a variation of colors to suit your preferences, from the standout yellow to the camouflage green. The sizes that on offer vary from 40 liters to 5 liters to cater for your needs.

I personally own one of these dry bags and can say that it is completely waterproof and trustworthy. When jumping off the rib to the beach, I usually chuck the bag on the water with my personal items inside. I’m very confident that the bag can be submerged within water and not a single droplet of water would leak into the bag.

Two things that I would mention is that the straps are quite harsh when carrying the bag for long distance on your shoulders. Also. the bag is quite hardcore inside with no padding, so bear this in mind when carrying fragile items and dropping this bag on the floor.

Overall, this dry bag is the perfect solution for a waterproof dry bag that is made from high quality polymer and is highly durable. Although it has two small flaws, I believe this bag will last a lifetime with plenty of use for the reasonable price I paid.

Earth Pak Roll Top Dry Bag


Similar to the Adventure Lion, the Earth Pak Dry bag 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 dry bag you choose is completely up to you but I always advise 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 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 if 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


Unigear offer 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 liter 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 offer 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 reasonable 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 under water 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 wont have as much weight and therefore this will not be an issue.
