Versatile and durable, your gear will stay dry inside these round bottom dry bags, even in adverse conditions. Shut out water by rolling down the top a few times and snapping the side release buckles together. Great for power boats, sail boats, personal watercraft, kayaks, canoes, camping, fishing, motorcycles, ATV’s, snowmobiles and car top luggage racks. You can even use it at the beach as a cooler!

What’s most important though is that it has an incredibly high tear strength and it’s pliable so you can easily load up and close the bag without struggle. Thermo welding technology ensures the strong seams are watertight. Your dry bag is crafted with reinforced construction at all stress points, making it even tougher!

To ensure a watertight seal, tightly roll down the top of the bag a minimum of 3-4 times & connect the buckle.

Product Reviews

  1. Fletch

    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!

  7. PA mom

  8. Donnel

    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.

Finally, an affordable carbon pole. Montem answers the most common gripe-price-with this sub-$80 offering that performs like it costs twice as much.

After about 40 hours of testing on trails, streets, beaches, and many places in between—including extensive handling and testing in a physical-therapy office, among therapists, nurses, patients, and doctors in an orthopedic group—we’ve determined that the Montem Ultra Strong Trekking Poles are the best for nearly everyone. They’re simple to set up and use, comfortable, and ready to take a beating. Also, they’re a bargain.

Montem Trekking Poles are a great deal for the value they provide. From committed outdoor enthusiasts to local strollers, these poles will offer a great work out, as well as a sturdy base you can rely on. For the price, it doesn’t get much better than this.

Montem nailed important details like choke-up extensions on the grips, in-field adjustments for the locking mechanism, and easily adjustable straps
