Love this lightweight dry bag. I've used other Sea to Summit dry bags on my paddle board, so I know how reliable they are with keeping the water out. I particularly like that this bag comes with a D-ring and attachment point on the bottom- haven't boarded with it yet- but loving that it'll be more secure then tucking it under the bungees. I've used the attachment points thus far to secure it to the outside of a small pack I use when doing short dog hikes. Planning on a few more uses and can totally see that this may become my new critter/bear bag. It's more substantial than what I'm using now but still lightweight. It looks like there's good abrasion resistance as well.

The Sea to Summit Lightweight Dry bag offers great protection when every ounce matters. The 8L is perfect to handle my clothing for a couple nights in the backcountry or gives me enough room to use as a sleeping bag stuff sack if I need full waterproof protection for my bag. I also love the option of the field repairable buckle; knowing that if something does break, it can be fixed without losing a piece of gear. The fabric seems durable so far and I don't have any doubt it will continue to hold up. Because of the weight, this will be my go to option for protecting things in my pack and canoe when conditions get wet.

Purchased two 2L drybags for my wife and I, to hold our smart phones, wallets, keys etc. We normally store our drybags in the day hatch of our Kayaks. While practicing our rolls, it’s understandable that some water will get into our day hatches. That’s expected. What wasn’t expected was that water got into my drybag, soaking my phone. Jury is still out on whether I’ll be able to get the phone back up and running. If not……$500 gone.After getting home I did a leak test on both bags. Filled them up with water to see if any would leak out. Unfortunately, both leaked like a sieve. These bags are NOT waterproof, as water permeated through the fabric, and not the seams. Totally disappointed with this product. Will not buy another.

Is anything completely waterproof? This bag isn't, but it's not bad either.I'm grateful to Sea to Summit for sending me the item at no cost to me in exchange for an honest review of the item. So I decide to put it through some tough testing. I'm really curious about the claim of being "waterproof" that is so prominent on the label.I started with two very tough tests on this bag: I filled the bag full of wadded up paper and some socks, then sealed it up and sunk it in a sink and let it sit overnight. The next morning I checked it out and the paper had beome somewhat wet.The second test I stuffed it completely full of paper and sealed it up agaain.

The next morning I checked it out and the paper had beome somewhat wet.The second test I stuffed it completely full of paper and sealed it up agaain. After I put it in the sink, I could squeze air out of it--which tells me if air can get out, then water can probably get in. I let it sit for several hours and came back. All of the paper was soaked and there was about a cup of water inside the bag.Maybe I'm expecting too much from the product. Maybe I'm not sealing it properly. Both are possibilities.On the sealing up of the bag: I was disappointed that the instructions were on the reverse side needed to follow them easily. If the instructions were on the other side of the bag, then the picture in the instructions would match the bag as you hold it--but it's not that way. The picture is on the opposite side so you have to look at the picture in the bag and then reverse it in your mind to seal it up right.For a third test, I decided to fill the bag up with water and seal it up, then put it in a large bowl (upside down) and let it sit for 1 hour. I would then see how much water leaked out. If it's going to keep water out, it also needs to keep water in. As I had feared, after one hour there was a good amount of leakage--nearly 1/2 a cup (100 ml) had drained out. Which means it could also drain in.I consider the possiblity that I'm doing it wrong--that's always something to consider! So I watch a few online videos. One recommends putting five to six folds in the top, another recommends putting your gear inside a plastic garbage bag and then putting that bag inside the dry bag. A third video doesn't tell me anything.So for my next test, I stuff with paper again, squeeze the air out, and put six rolls in the top. I toss it in the shower for 15 minutes to simulate a rainstorm. After 15 minutes I pull it out and the paper is wet--not soaked completely, but plainly wet. Certainly "dryer" than if I had put the paper in the shower without the bag at all--but the stuff's still very wet. It's at this point I think to myself that if I had actually paid for this product I'd take it back for a refund.I set up one final test: A bag in a bag. I get a common household garbage bag and stuff it in the dry bag, then stuff the garbage bag with paper. I then tie the garbage bag to stuf in the dry bag, and seal the dry bag as instructed. I then place it in a vessel of water to see how it performs.Immedaitely I find out that there is a good amount of air trapped in the garbage bag that I can't really "press out" easily and it is clumsy to work through. I do my best, but a good amount of air is trapped in the dry bag. I also wonder what happens in the field when I want to get at my gear in the bag and then re-close the bag--does the garbage bag survive being opened and closed multiple times.The final results of this test were that after two hours the inner garbage bag tied up DID keep everything inside of it dry, but the material between the garbabge bag and the dry bag had a good amount of moisture.I did not complete any tests on the strenght of the dry bag, but it does appear to be sturdy and durable. It certainly stands up to basic use without tearing, unlike a garbage bag alone.Good points:1) It collapses down very small and makes for a very nice container for water. I'm pretty good at bushcraft, but it's kind of hard to make a "bucket" out in the field.2) It keeps stuff "mostly dry" -- better than nothing at all.3) It is easy to open and close.4) It is easy to pack and unpack.5) Because air tends to get trapped in the bag, most of the time as regular pack of gear will float in water.6) If a buckle breaks, it can be replaced -- although I not test that feature.Not-so-good points:1) It isn't waterproof.2) It can trap air and become bulky to pack (although this leads to good point #5 above).3) The buckling system of rolling then buckling is awkward and takes up space in the pack.Conclusions:It's better than nothing, and coupled with a secondary bag such as a garbage bag, it can be a useful tool on trips where you expect the peril of extreme water--kayak, canoe, or rainforest hiking. I wouldn't trust it alone to keep gear dry--especially electornics gear. However, I'll use it on such trips because that coupled with a secondary bag is really just about the only hope you have--alternatives are just not available.I'm not saying I wouldn't use it--I am saying that i wouldn't use it by itself and expect it to keep the contents completely dry. It says it's waterproof, but it isn't.PLUS: A number of the reviews here are showing total success in keeping gear dry, and that is consistent with reviews on other websites. There may be tips and tricks that I have missed.
I have had many similar products over the years from various companies. Although I haven't seen the long-term (multiple year usage) effectiveness of this particular bag, I am hopeful it will serve me well for many adventures down the road. Absolutely LOVE that Sea to Summit made the buckle field repairable, only wish there was an extra buckle included for such needed repairs. I have the 8L bag that works well for storing items needed throughout the day (phone/camera, layer, rain gear, etc.) which allows me to not worry about getting into my larger pack while paddling. Seams are taped and even though they say it's not rated for submersion, I can testify that my bag got a bit wet and all contents were perfectly dry.
I've had this bag for about 2 months now and it has held up. I've taken it whitewater rafting, climbing, to the bottom of the Grand Canyon, and into the Alaskan wilderness. I have the 8 Liter bag and it easily fits my standard 3 season outfit. The bag is durable and I do not fear popping/tearing it like I do other dry sacks. The roll top works well and when folded correctly can expunge almost all air. The only feature I do not enjoy is the optional shoulder sling/strap. Although I have not personally tested the strap, the rubber tab that it hooks onto seems flimsy and I fear it may rip or even tear the seam of the bag. Also, a strap sold separately seems unnecessary.
I've been a pro with Sea to Summit for a few years, and have used a variety of their products. Because of the nature of many of my adventure trips, there have been a few items which have long become trusted friends since I first entered the adventure travel world back in 2011. First: context. I do difficult sports and engage in some pretty wild adventures all over the world, in all kinds of conditions. At 70 now, I've climbed some big mountains, explored the Amazon, and been in some very challenging environments. My gear HAS to work, it HAS to be in working order. The way I do that is by using Sea to Summit's dry bags.Every single trip, without exception, I use a packing cube, then slip that cube into one of the dry bags. This not only keeps my gear organized but ... MoreI've been a pro with Sea to Summit for a few years, and have used a variety of their products.

I do difficult sports and engage in some pretty wild adventures all over the world, in all kinds of conditions. At 70 now, I've climbed some big mountains, explored the Amazon, and been in some very challenging environments. My gear HAS to work, it HAS to be in working order. The way I do that is by using Sea to Summit's dry bags.Every single trip, without exception, I use a packing cube, then slip that cube into one of the dry bags. This not only keeps my gear organized but also protected. For example, I've watched my backpack sit in the soaking rain in Moscow, then when I finally get my hands on my gear everything is perfectly dry, even as my backpack looks like a wet dog. That's priceless.I love the new lightweight versions as they help me better manage the overall load. What I can't afford is wet down. That's not only inconvenient, you can be seriously compromised. So I count on the dry bags to guarantee that my stuff arrives safely.When I arrive and my tent is set up, arranging the bags inside is, for this military veteran, the easiest way to control mess in a tight space and allow me to find what I need in seconds. The inside of the bag is white so you can better see inside, I also tape a tag to the outside so that I know which bag contains what. I love organization, and tents can get chaotic fast. These bags make unpacking and packing back up a breeze.Frankly I can't say enough about them. Once I'm at my site the bags often get use for holding or transporting wet laundry or lots of other things. They dry out fast and are well used every single trip.Finally, while I have never had a buckle break and I must have some fifty of these bags in all sizes and all of them used and abused, the new bags come with a replaceable buckle. Here's hoping I never need one. To date my bag has performed flawlessly. I've tried others, this is by far the best.
While I admittedly haven't had many opportunities to run it through it's paces, it's been a solid a dry bag while pack rafting in Wyoming. The roll closure keeps a tight seal and the non-bulky buckle feels sturdy. It's ridiculously lightweight and even though the material feels paper thin, it managed to keep my camera gear, cell phone, battery charger, and InReach protected from the elements. If it's anything like the Evac Compression bag that I've used all over the world, then I'll be a happy camper. So far, so good - looking forward to more adventures with this dry bag.
The Big River Dry Bags are perfect for my canoe and kayak trips. SUP's too. They are tough, water tight, durable and the tie down grommets make for a dry secure load. I bought several sizes and like them so much, bought more to give as gifts. Everyone loves them.I also bought several different size Lightweight Dry Sacks, and am just as happy with them. I do a lot of 2- 7 day overnight backpacking trips in Maine, New Hampshire & Vermont. The bags are used constantly.
