    Purchased two 10L dry bags for a dive trip my wife and I were going on. Used them every day for boat dives where sea spray and wet conditions all around. Not once did any or the items in the bag have even a drop of water inside. The carry strap was a convenient feature, as we had to carry our other gear on and off the boat daily. Easily carried all the items I needed. We also used the bags to carry items we had purchased instead of carrying bags. The product seems sturdy for carrying a good amount of items. Good product at a good price.

    I bought the 5L, 10L, 20L, and 30L oceanum db for my kayak team, and they worked like a charm. All of our electronics stayed dry. One bag fell into the water, and to my excitement the seal held perfectly. No damage at all, no water leak. Excellent product.

    Awesome little bag! I purchased the 5L in order to just fit my phone and DSLR and it is the perfect size. Works great, looks great.

    I did research on which drybags were the best, and this was the brand that scored the best, the bag is plenty big, I ordered 2 of the 10L the material seems really tough, I haven't actually tried it out yet in the water to see how well or does.

    Running an adventure company, we use a lot of equipment. These bags hold up well, keep items dry and at a great price point!

    I have not used this item yet, so I can't comment on that. But I am very impressed with the fabric. It is much thicker than other dry bags I've used. It appears that it would hold up well and keep things dry. I also like the bright yellow color, which makes it easy to locate when it's stowed among other gear and bags.

    Bought this as a gift for my boyfriend. We are constantly kayaking in the summer and this is just the bag we needed! Haven't used it out on the water yet, but seems like it will be perfect.

    Took this bag on a trip to Puerto Rico in early March. It worked well keeping our belongings dry. We took it on a hike in El Yunque rainforest down to the waterfall. I didn't submerge the bag, but there was a lot of spaying water and the rocks surrounding the waterfall were very wet. Our gear stayed dry. The shoulder strap is very handy for carrying the bag and being able to keep your hands free while scrambling over wet rocks. The 20L volume holds enough items for a day hike. Prior to my trip I tested the bag in my pool, but putting in a dry paper towel and sealing up the bag and tossing it in the water. I let it float around the pool for about 5 mins before taking it out and checking it. The paper towel stayed dry, only a few drops got into the bag, and that was upon opening it back up and water on the rim dripped into the bag, again no more that a drop or two. All and all the bag performed well for the limited exposure to water that it got on my trip. I will see how it holds up over the coming months on a few fishing trips I have planned.

    This bag was awesome! We were going to go snorkeling at one of the beach parks in Hilo, Hawaii, so I decided to use this with all the electronics I was bringing. I bought the largest size since it was only a few more dollars than the next size down. It was large enough to store the following and still have room: Sony A6300, Meikon underwater housing for A6300, GoPro Hero4 Silver, wide-angle dome correction lens for underwater housing, spare batteries, cell phone, GoPro accessories, sandals. I set the bag on the rocks awhile we snorkeled for the day and came back to all the items still dry. There was a point where we had to carry the bag through the water. Even the a quarter of the bag was submerged and water was splashing on the bag, the items continued to stay dry. Great for transporting electronics near water especially camera gear.

    I took this bag on an 8-day trip to Thailand that included a lot of water sports. Not once was there an issue or concern with water or sand making contact with the contents of my bag, where I often carried my unprotected DSLR camera. The PVC material and stitching are of the highest quality. The only downside is that 2 beach towels will easily consume 75-85% of the bag's capacity. No other complaints - amazing product, and terrific value!

    The dry bag is great, I camp hike and am getting into kayaking so for my lifestyle dry bags are a must. This is exactly what I ordered will do more business with the company.

    I went with the Montem Waterproof Bags after looking at reviews from boating professionals, plus read through the reviews here on Amazon. Sometimes Amazon customers notice features or issues not picked up on by the pro's. The Montem bags do look and feel substantial. They are obviously well-made and do their job on the water (we have kayaks). I just hope the company keeps making them at the current price and quality.

    This bag is amazingg! I went on a backpacking trip through Death Valley on a weekend where, oddly enough, it quite literally rained non-stop for 24 hours. But, this bag kept everything completely dry. It packs down well, and its also good for clipping onto the outside of your pack. The product is sturdy and well-made, and for an amazing price. I really think this bag could rival any other big-name outdoor brand in terms of quality. I definitely see myself purchasing more of these bags and other Montem gear in the future.

    Great bag, though I wish now that I could find one with 2 straps so I could wear it as a backpack. Very well made out of thick material that I can tell would be difficult to puncture.

  26. Rain C.

    Rated 5 out of 5

    This dry bag is seriously amazing. First of all, it works perfectly in keeping all my gear bone dry, even after complete submersion a few feet down in the water. Second, it fits a lot more than you'd think from how it looks on the outside. I have the 20L, and had 3 large water bottles, a towel and few medication bottles in there with room to spare. Yet after it packs down and rolls up it's not bulky at all and looks attractive as you carry it. This bag solves a problem I've had for years of not being able to take certain crucial items out on the water with me as I'm snorkeling off a kayak, always having to return to shore to get my water and medication. Now I can have it all with me as I go and I don't have to worry about it getting wet. Another cool thing I discovered is that it doubles as a flotation device. Just pack a little extra air in before you roll it up and since it's watertight it floats strong enough to keep me (130 lb.) afloat if I need a rest from swimming. Very cool. This bag could be made extra awesome if there was another strap added so that you could wear it on your back or front like a small backpack. Still, it works great as is and I love it and recommend it!

    Excellent waterproof bag. I use it for kayaking and appreciate having the smaller sizes available, which makes for more efficient packing of the kayak.

    I'm a sailor, so dry is a real need. This is a very high quality materials container, great sealed seams, great closure, and several options for the carrying strap -- well thought out. It is about 18" tall and about 8" in diameter. I'll happily recommend this to anybody who wants something that delivers excellent value.

    This is quality gear at a reasonable price! Having kayaked for years I know the value of a good dry bag, however these bags have so many more uses. I use them in emergency packs to store essential gear that needs to be protected from moisture and these bags provide an additional level of protection but are easy to access when you need something. The other day I had a training class that required me to bring a sack lunch and water (we were in the desert)... I used the small bag, froze some of the water bottles and my bag kept everything cold and was easy to carry with the straps attached. The construction of the bags is very high quality, the seams and attachment points are heavy duty as is the hardware that attaches the straps. Highly recommend!
