Best Marine Dry Bags of 2025

“I had a bit of trouble getting the seal to lock properly at first. I laid it flat in the sun to help shape the opening and remove shipping creases. Overall, the bag is durable and a good size.”

“This dry bag is very straightforward. It's perfect for keeping small items dry at the beach or poolside. I especially love the seafood window pouch that allows me to use my phone while it's still protected. Such a convenient product!”

“I really appreciate the size of this bag. It fits my keys, phone, and a light windbreaker perfectly. The material feels thick and durable, and the internal ziplock pocket adds extra protection for my phone. I had a great experience using it while paddling.”

"I packed a TON of stuff in here for a 2-day kayak: clothes, tent, toiletries, and other various camp items. It is very large and held all my stuff easily. Even in a rental kayak that got some water in the bottom, this kept my things dry. The material is thick and not flimsy, and the buckle is nice and sturdy. I highly recommend it for the price point. I've only used it once, so I’ll wait to see about durability."

"I took the Earth Pak Waterproof Dry Bag on my last trip to Hawaii, and it performed perfectly on the beach! It kept everything dry and felt really well-made, with plenty of space for what I needed. Whether it was towels, sunscreen, or snacks, it fit a lot more than I expected. I just wish it had smaller pockets inside for items like keys or sunglasses, so I wouldn't have to dig through the entire bag to find them. Overall, it’s a great bag!"

"I recently bought the 40L version mainly because it doubled as a backpack. I was preparing for a mountain bike ride where I heard it could potentially rain and snow. This bag held my spare shoes, long sleeve jerseys, windbreakers, and a towel with plenty of room to spare. The day of the ride was beautiful, and I didn't have to worry about my gear. It was secure, the chest strap held well, and my contents were safe the whole time!"

"I’ve used this 3L bag for years with my canoe seat back. The 1L version is perfect for my Pixel 7 Pro in its case, and still has room for my wallet and keys. The magnetic closure is ingenious and it’s easy to open. It has never leaked, but I wouldn't submerge it. I love that it attaches easily with Velcro straps."

"I appreciate the size of this bag and how much it can hold. There’s a little elastic net inside for separation, and the material is high quality and easy to clean. I love the magnetic closure over a zipper; it makes it much easier to handle with wet hands."

"I've seen this bag highly recommended in fly fishing forums. I got the 1L option for solo beach trips and tubing. It fits my phone, wallet, and keys while leaving room for more. After swimming for over 45 minutes, everything stayed completely dry. Just a tip: if sand gets on the bag, wipe it off the magnet before closing to avoid leaks."

"I've used the smaller dry sack for my running pack several times. It keeps all my stuff organized and dry. Unbelievable price for an essential piece of gear!"

"These bags are a great size and price. They are pretty durable as well and I appreciate the different colors for easy identification. However, they're only slightly water-resistant, so be cautious in rainy conditions."

"I found this dry bag to be a great size, as it holds everything I need for two people, including wallets, phones, and jackets. The backpack straps make it easy to carry around. We use it not only on water but also on dusty roads while driving."

"I took it paddle boarding, and it worked exceptionally well. It kept my clothes and phone dry, and I plan to use it all summer long!"

"I bought this bag for my trip to Costa Rica with my son, focusing on hiking and water resistance. The quality was impressive, leading my son to choose an Earth Pak too. Throughout our two-week adventure, our bags were our only luggage, fitting perfectly as carry-ons. During a boat ride to Drake Bay, while others struggled with heavy canvas bags, we jumped into the water with ease, and our contents remained bone dry. The bag's size was perfect, and I highly recommend using packing cubes for better organization. My only wish is for a hip belt for longer hikes, but overall, it's been an excellent purchase!"

"I recently got the Earth Pak Waterproof Backpack in the 85L size and it has surpassed my expectations. As an outdoor enthusiast, I've long sought a truly waterproof backpack. During a camping trip, I left it out in heavy rain for days, and everything inside stayed completely dry. The roll-top closure is effective, and the size is just right for all my gear. Comfort is also a strong point; the cushioned back panel offers excellent support. I appreciate the included phone case for added security. I wholeheartedly recommend this backpack for anyone who enjoys outdoor activities!"

"I’m really pleased with the Earth Pak backpack. The external waterproof pocket is perfect for quick access to my phone and wallet, while the internal pouch keeps smaller items organized. The construction feels solid, and I would definitely purchase it again!"

"I purchased this bag for a rugged adventure camping in the Guyana Highlands. After 12 days of travel with 8 plane rides and camping, it survived with just a scuff or two—no tears or broken straps. I highly recommend this bag; it's 1/4 the price of its competitors and performed admirably!"

"I bought this dry bag after a cheaper one tore. It held up remarkably well during my 1,600-mile motorcycle ride from Dallas to Tampa, even through heavy rain. I love the number of retaining points, making it easy to secure to my bike. I highly recommend this dry bag!"

"I used this bag for a 3-night camping/kayaking trip for four people. I was surprised by how much it could hold and everything stayed bone dry despite a rainy night. It was lightweight and latched easily onto the kayak. I might purchase a smaller one for shorter trips!"

"I purchased these bags for a Philmont Trek. While July 2023 was dry at Philmont, we tested them thoroughly before our trip. We packed dry towels, wrapped them four times, and submerged them in a 5-gallon bucket for about 40 minutes. They are not 100% waterproof, as some moisture appeared at the bottom and a little at the opening. However, this leakage is minimal and likely wouldn't pose a problem during regular camping. They are super lightweight and made from tent material with seam sealing, making them a good compromise for light and easy use."

"I bought this 5-pack for family kayaking trips. During our 2-hour trip, my dry sack sat in a pool of water, yet everything inside remained completely dry. The different sizes were a great bonus for us."

"I ordered these bags for Christmas wrapping. I packed a hooded swim shirt and bathing suit in each bag for boating and kayaking. The variety of sizes helps keep everything organized, and the smaller ones are perfect for stowing away phones and chargers while we're on the rivers and lakes."

"I recently used the Hypalon dry bags to cover my new Fulton F2 cast aluminum winches on my Sea Doo trailer. These bags are incredibly flexible and long-lasting compared to standard plastic options. They keep my winches dry and free from corrosion during outdoor storage, and the snap lock straps are just right to secure them even while towing."

"During a camping trip with my son's Boy Scout troop, I took my Sea to Summit Big River Dry Bag. It was completely exposed to heavy rain for thirteen hours, and I was worried about my gear getting wet. However, when I opened it the next morning, everything inside was perfectly dry! I couldn't be happier with this bag. It has my highest recommendation!"

"I absolutely love this bag! It has saved my belongings from getting wet while on the river. One important note is that you have to fold it over several times to maintain its effectiveness, which does reduce the volume a bit. Overall, I own both a small and a large and they've been fantastic!"

"I really like the design of this pack. It's simple but well thought out, with features like a sternum strap with a whistle and loops for hanging items. The two cup holders are handy for my water bottles. While the main compartment is water-resistant, I do have concerns about the long-term durability of the taped seams. Overall, it's a great option for hiking near water."

"I bought this pack for a trip to Machu Picchu. It held up well during my 3-week adventure, providing ample room for my camera gear and other essentials. My only issue was that in humid conditions, moisture would build up inside. Still, it kept my gear dry during an unexpected rain at the site."

"I was hoping for more from this pack. It's lightweight, but it feels like cheap material with not enough pockets—just two, plus the water holders. I'm considering whether to keep it, as it seems like a big, expensive garbage bag."
