  • Great product.
Color: Yellow Size: 30L
I bought this for a weekend canoe trip. The material is very sturdy and the capacity is very good. I like that it has a window so I can remember what is in it compared to the other dry bag I have. It preformed well and is a good value.

  • Holds Water
Definitely a heavy duty material and the clip feels strong enough for me to grab the lot quickly without concern the whole thing will unravel. The bright color helps on those trips without much light source and the window is the best part: I often pat myself on the back for how well I tetris my items thoughtfully in a pack. Only to have to undo all that work because the one item I needed was also packed away. Being able to see my own stupidity through a tiny window has made the experience so much better. ... show more

  • The Water Proof Hike Sack is A must Have.
It works, everything stays dry and safe. I took it paddle boarding, kayaking and primitive camping. It kept everything organized and I did not have to fumble around looking for my stuff in the dark. It was in the bag on my shoulder. Nothing got lost or misplaced for a change. You know how it is when you are busy and in a new environment setting up camp. Stuff gets misplaced so you wander around looking for it. Keys, phone, wallet, solar charger, dry socks, flashlight, batteries, knife and dry outfit all fit in this bag. I have a second bag for 2 days of food and water. ... show more

  • Ok for the price, honest review
Color: Yellow dry bag combo(with phone case) Size: 20L
I don't write a lot of reviews but felt compelled to write one. We have kayaks and were looking for an extra dry bag that was reasonably priced. Let me preface this by saying that we bought a dry bag from Walmart first. There wasn't a selection, they literally had one, so that's what we got. If I wouldn't have gotten first, I wouldn't have had anything to compare it to. When I initially opened the package I looked over the dry bag (I got a 20L yellow one to match my yellow and black kayak) the material seemed kind of thin and cheesey, almost rubbery-plastic like compared to the one from Walmart, which kind of surprised me. Side by side, the one from Walmart ("Outdoor" brand) seems to be made out of a material that is much heavier and appears very waterproof. The stitching on the bottom of the Amazon bag was also questionable and messy. I do like the see through window, it was nice to be able to locate something quickly while out on the water. The plastic hooks on the ends of the straps are flimsy and look like they will break easily. I was excited about the phone holder until I actually used it. It made great sense when I ordered it, but I was most disappointed with it. I take an old phone with me when I kayak so I don't risk losing my good one in the water. I have an old Samsung Note 9 that I use for pictures when we're kayaking. It's a larger phone. It slid into the phone holder snugly with no excess room. The inside of the phone case had three ziploc type sliding seals which you then fold over three times, then it snaps using snaps. It was fine putting it in but awful to take out. Obviously if you're out on the water it's most likely warm outside. The heat basically melts the plastic to your phone and creates a vacuum which made it very difficult to remove the phone from the little pouch. It was a lot of steps to take the phone out and put it back in, especially if you're in a kayak floating in the water. I guess it's ok if you just want to take your phone, and not actually use it when you're on the water. Overall, I gave this 4 stars. The quality wasn't there like I had hoped, but it did the job and I will continue to use it. It did hold air when the bag was closed and the buckles were latched to make the handle. None of my stuff got wet and there's no doubt that the bag will float if it falls out of the kayak. It does what it needs to do, but I feel like the bag from Walmart will hold up a lot longer (it doesn't have a carry strap though :/ ) I'll probably get a better strap for the bag. If you're looking for something basic and inexpensive, this will do just fine. I would consider purchasing another one down the road if this one holds up. ... show more

  • Perfect storage for my rainsuit

Perfect storage for my rainsuit once rolled up. Keeps it clean and protected while moving and storing. Perfect without breaking the bank.

  • Good value!
Color: Orange Size: 20L
Price is cheap but quality seems good. Material actually is thick and sturdy unlike some of the other ones I got from amazon. Haven't tested in water yet but will update if it fails!

  • Just like any "dry" product
Color: Yellow Size: 20L
Just like any "dry" product, I like to test them out before I put anything valuable in them (for example - see my "Cookie Test" on this product - NEW! KastKing Waterproof Dry Bag for Kayak, Fishing, Canoeing or Camping Trips - Tough Durable 100% Waterproof Floating Roll Top Dry Bag (5" Wide X 7" Long) ). This bag would also have to pass a test. This is my 2nd KastKing Dry Bag. My other one is the 30L version. This review is for the 20L size. The bag itself looks very sturdy and makes you think immediately it is a quality product. The material is thick and the buckles on the shoulder strap swivel (nice touch). I took the bag and sealed it up with 4 turns and filled my bathtub with water. I took my biggest pipe wrench (weighs about 10lbs) and used it to submerge the sealed opening under water. Then I went for coffee and cruised the Internet for a while. After about an hour I remembered I had left the bag in the water - I went back, pulled it out looked at it. There is a very nice viewing window (BTW - especially helpful on the HUGE 30L bag) and I looked inside while I shook the bag while turning it. There was absolutely NO water - not even a drop. As far as I'm concerned, this bag passed the test with flying colors and I will have no worries about it protecting my gear on my next fishing or sailing trip (whichever comes first!). I added some pics of both bags so you can get a reference for size. The 30L is much larger than the 20L (hard to tell in the pics). When flat: the 30L is about 15.5" x 28". The 20L is about 14" x 24.5". On a separate note about KastKing - I've been a customer of theirs for a few years now (love their braided fishing line!). They've always been very responsive and helpful on the customer service end. DISCLOSURE The product was provided to me free of charge on the promise I would provide an honest and unbiased review of the product from first-hand use. They asked for accurate feedback whether positive or negative. ... show more
