Rated 3 out of 5 by from Extra layer of protection I bought this right before going on a Smith river trip. I used it to protect my DSLR camera and lenses throughout the trip. IMPORTANT: This bag is not certified submersible and I never let it go in the river. I put my camera in the dry bag then into my large, Completely waterproof NRS, drybag with my other gear. This bag was used to protect from rain and splashes while allowing me to keep the camera close at hand.

Rated 3 out of 5 by from You can't submerge it, but it kept my stuff dry I was shocked to read on this item's label that it should not be submerged. I thought the whole point of these things was that if you topple over in a canoe with all your stuff, they keep your stuff dry. Apparently not. Additionally, as you'll see in the photo of the instructions, you're expected to use two of these (very pricy) dry sacks for "sensitive electronic equipment." I solely purchased this thing for my camera and phone. If the product itself doesn't do the job you promise it will, then it's defective, or your claims are deceptive, you can't expect your customers to purchase two of your products to get them to work properly. Would you expect to have to wear two pairs of waterproof boots on top of eachother in order for them to be waterproof? With that said, I bought an additional Ziplock-style dry bag at the sports-goods store that said it was "Scuba-certified" to utilize inside of this Sea To Summit bag just in case, and my phone/camera did just fine through waterfall-hikes, canoe trips, rough water on the speedboat, snorkeling, mangrove-swamp trekking, etc. I never dropped the bag in the water, but I did leave it on the bottom of the canoe at one point, which did have an inch or two of water in it, and everything stayed dry. The sealing mechanism, where you simply roll the top down, seems bizarrely simple, and I cannot fathom how that makes it waterproof, but, there really weren't any better options at the sporting goods store, they all seem to use this same mechanism.

Rated 2 out of 5 by from Not really waterproof I bought the small bag about a month ago...it's not waterproof when it falls into water........it may be ok with rain but I would not suggest you use it for your phone or any other valuable electronic.

Rated 5 out of 5 by from Great to have smaller sizes This is an excellent waterproof bag. I use them for kayaking and appreciate having the smaller sizes available, which makes for more efficient packing of the kayak.

Besides price, what is the difference between the Sea to Summit Big River Dry Bag and the Sea to Summit Lightweight Dry Sack? Is one better rated for submersion over the other?

Asked by: JeffM
​The Lightweight dry sack is less weight than the big river dry bag and is made with 70-Denier Nylon making it ideal for backpacking. The Big River is made with 420 Denier Nylon coated with tough thermoplastic urethane making it more rugged but also adds to the weight and makes it ideal for paddling and watersports.

Is the 18 inch height talking about the entire length of the bag unrolled or the length when the top is sealed properly?

Asked by: potato
Yes, the length of the Lightweight Dry Sack is measured from the bottom of the sack to the top when it's unrolled.
