KastKing Cyclone Seal Dry Bag

I got the bag as a Christmas present. It didn’t come with instructions. For the life of me I can’t figure out how to roll it to make it a waterproof seal. Can anybody help?

Use it during a torrential downpour and everything inside stayed super dry. Excellent product.

Dry bags are one of those products that you didn't realize you needed until you have a few. The KastKing 30L dry bag is ideal for carrying a full change of clothes if you're someone who works in or around the water and getting into something dry and warm could be the difference between life and death.I do a good bit of kayaking and duck hunting. Both activities put me in or near bodies of water that are hovering just above freezing temperatures. Because of this, it's important to keep emergency supplies on hand, like a full change of clothes if you were to fall in the water. Of course you can also carry nonessential items as well, like beach towels, food, and other stuff. This bag is large enough, and the design is sturdy enough that I would feel totally comfortable storing clothes, fire starters, flares and signals, and other emergency equipment in a kayak, boat, or ATV.The bag is of good quality and appears to be 100% air and water tight. Mine arrived with two shoulder straps, presumably so I could use it as a backpack if I needed to. Pricing was great and delivery was quick and efficient. I would recommend this to anybody who worked or played around water, dirt, sand, or mud. It also came with a dry bag for your cell phone, which is a nice added bonus.Overall, I'm impressed with the item and look forward to many years of use with it.

I'm really pleased with the 20L Dry Bag.After first inspection all seams, strapping, buckles and zipper are all very well sewn. First time I sealed the bag it took me a couple minutes to perfect my method but the bag is absolutely AIR TIGHT! The zipper opens into a small pocket perfect for smaller items you don't want to dig for. The built in handle is very nice but it does limit you on how small you can roll the bag. I've had dry bags in the past that you carry from the sealing strap and I would rather have a dedicated handle to prevent wear and tear.The phone bag fits my Galaxy with an OtterBox perfectly and seals with 3 zip locks and 2 outer snaps. The screen and camera work great too while in the phone bag.Great Value and Quality, Thank You Kastking

I purchased the 10l dry bag for float tube fishing. I wanted a place to keep a towel, my keys/wallet, maybe a spare shirt. Stuff I wanted on me but wouldn't need and didn't want to get wet.The first thing I did when I got my dry bag was try it out. I rolled it as instructed and gave it a giant bear hug and tried hard to squeeze out the air inside. I was able to get it to "unroll" once, but I squeezed way more than I think this bag will ever have to endure on the water and it held up fine.I filled up a 5 gallon bucked and stuck some tissues in the phone case, and dry bag (big compartment and zipper one). I then submerged the bag and phone case and left it there for hours. I came back and the inside of the bag was dry. I did notice when I opened it, a little bit of water came in because of the way I was holding the bag. Some of the water that was on the outside sort of trickled in because I was pushing down on the lip. That's my bad though.There is a plastic liner on the top of the dry bag that I think helps with the seal? It is sort of clingy getting stuff in and out, for me this is fine since my intent with this bag is to keep a few select things dry while I'm on the water, and then grabbing them when I'm off. If you're going to be opening and closing this bag a lot, this would get annoying.The outside zipper compartment is definitely not waterproof as the damp destroyed tissues would attest to.The phone case seems solid. The tissue was dry. I like that it's floating. The mechanism is there are two clasps the hold together the folded part. You can fold the case three times (like the dry bag) and on each fold is a sealing clasp (like a ziplock). But I don't think the mechanism to get a phone in and out is very convenient. I have a different case with 1 zipper and clasp covers that clamp down. I think I'll stick to that one, though this is a nice backup or gift to someone else.I'm very content with the case, confident it'll do well in the water and keep my stuff dry.
