Sea to Summit Big River Dry Bag Review – Protect Your Gear!

Looking for a durable bag to keep all your stuff dry while out on the water? You came to the right place! The Sea Summit is a bag that you can grab everywhere, whether behind your boat or on rough surfaces without worrying it will tear apart or leak in the middle of your trip. Check out the Sea to Summit Big River Dry Bag review so you can find out about its excellent features and most importantly, how it will make your trip more pleasant than ever!

What is the Sea Summit Big River?

It’s a spacious storage sack for keeping your gear dry under any weather conditions, meaning it will withstand rain, dirt, snow, and sun thanks to its stiff material.
Its closure system is similar to other dry bags in the same category; it closes by rolling the top a few times, which make it completely waterproof.




The Sea Summit is made of a heavy-duty material called 420 D Nylon, which is extremely strong, lightweight and smooth. For a better understanding of this fabric, it is often used to make military parachutes, style- backpacks and outdoor gear. It provides not only a high level of waterproofness but also tear resistance and durability.


Closure System

What makes the Sea Summit waterproof is its stiff material and its closure system, that’s why it is crucial to close them well. The top needs to be rolled down several times and clipped with the help of the two buckles to secure the bag thoroughly.


Lashing Points and Portability

The Sea Summit features two handgrips on each side of the bag that allows you to grab it and move it from one place to another with ease. The two D rings placed on the top comes in handy if you want to attach it to your vehicle such as to a boat, motorcycle, kayak, truck to name a few. There is a downside though; this bag cannot be worn on the back since it doesn’t feature any shoulder strap. The only way you can carry it is by its handgrips or by the top unless you use your own strap.


Storage Capability

The Sea Summit comes in different sizes and, of course, the bigger the bag, the more stuff you’ll be able to store in it. Let’s see what this bag is capable of holding!


3L: Small items
5L: Small items such iPhone, wallet, camera, etc..
8L: Clothing for one day out
13L: Clothing for a weekend trip
20L: Clothing for a three-day trip.
35L: Clothing for a week trip
65L: Clothing for more than a week trip



The Sea Summit comes in six different colors: Blue, Green, Orange, Black, Yellow and Apple Green. The brighter, the better because it will be much easier to spot it from a distance or in the dark.



The company warrants the Sea Summit against any defect in the bag for one year.


How to Seal the Sea Summit?

If you want your bag to keep your gear dry, then you need to close it properly. However, it’s very easy to do it. Fill out your bag at three quarter, then roll down the top a few times until it’s tight. Join the two extremities and clip them with the two buckles.

Is The Sea Summit Submersible?

To be frank, dry bags are not designed to be fully submerged underwater for a long time. They float incredibly well without leaking as they provide excellent buoyancy. However, one thing you can be sure of is that it is waterproof if closed properly.

How to Care for the Sea Summit?

You don’t need much to maintain the bag. Clean it with a bit of Lukewarm water, a rag, and gentle soap. It’s also important to aerate it after each use to avoid moisture and bad odors.

Who is the Sea Summit For?

Whether you are an avid sportive, watersports lover, an enthusiast backpacker, or a sailor, you can honestly count on the Sea Summit to keep all your gear dry while you enjoy your activity. Many dry bags on the market are lightweight but don’t withstand heavy abuse whereas the Sea Summit is a bit heavier but extremely durable.

Should You Buy the Sea Summit?

So far, the Sea Summit has been receiving hundreds of five-stars reviews from Amazon customers, which mean something. However, if you don’t want to worry about your stuff getting wet while on the go, then you may consider getting this bag.

  1. What a great review of this dry bag I use a dry bag for my electronic gear that I hike with but prefer to stuff the rest of my gear loose in my pack. They are truly worth their weight if you intend to be on the water or need extra protection for other reasons.

    • Hi Lussier,

      Thank you for sharing your experience with your dry bag, I really appreciate!

      Yes, dry bags are worth the investment, especially the Sea to Summit Big River as its material is exceptionally rugged! 

      Thank you again for this useful comment and I wish you a lovely day!

  2. Good review of a good product, Video really helps. The bag seems like must have for whoever is at the sea or river or just plainly wants to protect his/her belongings from getting wet. It is probably originating from the military as most heavy duty products do. However, it is a big problem that it can’t be worn on the back because when you are on the adventure of any kind you want both of your hands-frees. Prices are reasonable, so this downside might be overlooked.

    • Hi Alex,

      I am glad you found the review and the video useful! Yes, it is a rugged bag that will undoubtedly keep stuff dry when out on the water. Indeed, as I mentioned in the article, this bag doesn’t have any strap. So, yes, it will be difficult to carry it while on the go. Be aware that some dry bags contains straps, but their quality is not as good as the Big River. That’s something you should consider. Many people use their own strap to carry the bag, and it works great.

      Thank you for the comment and wish a fantastic day!
