    • Keeps things dry, what more could you want?
Color: Yellow Style: 8 Liter
This is my boating bag and I haven’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.

    • 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

    • It works!
Color: Orange Style: 3 Liter
I used this when I went to float the river. It kept my phone and keys dry! no water leakage at all. I liked the size and it is easy to use.

    • Perfect for motorcycles
Color: Apple Green Style: 65 Liter
I pack alot of stuff on motorcycle trips. I could not find any bag long enough to fit my skateboard. This one fits my whole board without taking anything apart, as well as shoes, knee pads and whatever else I have room to fit in there. It also has tie down loops I can tie the whole bag down with and know it's not going to move while riding. Love this bag. ... 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

    • Exceeded Expectations
Color: Apple Green Style: 20 Liter
I use this for commuting and I would say that it has exceeded expectations. Keeps everything bone dry. Pretty sturdy. And a lot cheaper than others around the same quality. Might get one with a vacuum valve in the future as I often forget to push out the air before closing.
