    • Great fabric - wish they had a smaller size
Color: Royal Blue Style: 5 Liter
I think this will last a very long time. Not sure how much it will be used, but needed it for a very wet trip to protect a small point and shoot camera. Wish it had come in a smaller size. It did the job.

    • Liked it so much I bought another in green.
Color: Yellow Style: 8 Liter
I am new to kayaking, and dry bags, so I read a...er...boatload...of reviews. I needed one for my maiden voyage, and finally settled on the Big River 8L bag. It was perfect. I got a Sitka hooded sweatshirt, a small towel, and a couple of bananas and fig bars in there with a bit of room to spare. Not too big, not too small. Sizing descriptions on various sized bags were exceptionally confusing. Like nothing fits in a 5 liter except maybe a pair of socks and some lint. In an 8 liter, you could get a sleeping bag and a puffy coat. A 10L, you could put your boat in it, and so on. So I was lost at what to get. A 10L seemed huge for a couple hours of playing about on the river. A 5L seemed like it might be too small, so I split the difference. In my highly inexperienced opinion, it's about perfect for a day outing if you aren't bringing your house with you. It got wet outside. It did NOT get wet inside. It seems very durable, and I used the clip and a carabiner to ensure that it would go downriver with the kayak in the event that I went swimming inadvertently. I'm glad I sprung for the extra quality. I figured with trips with my dog to the coast and other things, it would see good service to warrant the little bit higher price. I have not used it a lot yet. It's going out again tomorrow on a kayaking wildlife tour. A three hour tour. IYKYK. But I am looking forward to putting some miles in with this bag and expect it to hold up well. ... show more

    • Keeps things dry, what more could you want?
Color: Yellow Style: 8 Liter
This is my boating bag and I havenโ€™t a bad thing ro say about it. Take it in the water with you while you swim to shore or get soaked on the river with super soakers and everything in this bag will stay dry.

    • Discovered leak despite very little use
Color: Orange Style: 5 Liter
Review Image by Sam Sam
Discovered the seam at the bottom of the bag developed a leak after what was very little use of the bag. I discovered this after placing water in the bag and noticing that the bottom of the bag was wet. I later confirmed the leak after drying and retesting the scenario making sure not to get the outside of the bag wet with the faucet. I would not recommend this dry bag. Edit: After reaching out to the company for a warranty replacement, they agreed to send me a replacement at no charge and no need to send it back. Added a star for this. ... show more

    • Quality gear is hard to find. Sea to Summit Big River Dry Bag is awesome!
Color: Royal Blue Style: 13 Liter
I purchased the Big River Dry Bag 13L. It works really well for me, and I'm glad I didn't try and save a few dollars by going with a cheaper brand. I use it to put my phone/wallet/keys/snacks/sunscreen in when I'm on the water for short trips. The thorough and evident quality of the dry bag makes it worth the investment as a quality piece of gear! PROS: - Durable exterior. I don't think anything rocks/scrapes would ever break it. - The top is easy to roll up. If I don't put as much in the bag one day, I just keep rolling it. - I like the 2 D Rings on the buckle. I use the D Ring and a carabiner to keep my bag where I want it. It's nice that there are 2 D Rings, not just one. Also, the D ring is big enough to use a pretty thick carabiner (like you would take rock climbing). - The buckle itself works well. Not flimsy. I've never had to use a repair buckle, but it's nice that they think that far ahead. - There are two side areas that you can use to strap the bag down. - When I'm storing it, I roll it back up (from the bottom) just like it came in the original packaging. The fabric isn't folded in any way that puts stress on it if I leave it in my garage or bottom of my pack for months at a time. - I also like the oval shape of the bag. I feel like there's a lot of wasted space in circular bags. They say the oval prevents it from rolling, and makes it easier to pack. That might be true, but I like the oval because it does a better job holding my gear. - The fabric is great for sliding in and out of a bigger pack. CONS: - Sometimes when I roll it from the top, the D Rings have a tendency to get "rolled up" into the roll. - I don't think I have any other cons! Another HUGE pro --> I reached out to the Sea to Summit customer service team and they were enormously helpful. They were prompt, descriptive and empathetic. I could really tell based on their tone and message that they embrace the outdoor lifestyle, enjoying nature, and being sustainable. I think they're based in Colorado, but they opened the email with "G'Day!" ... show more

    • Perfect size for valuables..
Color: Orange Style: 13 Liter
I've used a 13L Sea to Summit Light Weight Dry Bag for well over five years to protect and carry any and all on the water; keys, handheld VHF, fly boxes, hemostats, etc. It finally developed a small pin hole, probably my fault. In replacing the only thing I wished it had was more "structure" so I decided to try the Big River bag in the same size. The fabric is much stiffer and I'm sure will be more durable. The additional lash loops are a welcome addition but I do miss the "D" ring on the buckle so I've added added one for an additional attachment point. Great bag! ... show more
