Perfect Montana Travel Companion

I used this for the first time last weekend for a boondocking camp trip in the Pryor Mountains. I don't have to worry about this bag getting thrown in the back of a dusty truck or being left out in the rain. It's completely water proof with a zipper like a zip lock bag essentially. The shoulder carry straps are comfy. there are two mess pockets on the outside of the water proof bag for things you don't need to stay clean/dry. Would definitely recommend this duffel for anyone that likes to travel to dirty places. Would also be great for boating.

Great Bag

I recently purchased two High water duffel bags and I couldn't be happier with my decision. The bag exceeded my expectations by keeping all my belongings dry even in heavy rain. The material is durable, and the design is sleek, making it perfect for both outdoor activities and travel. The spacious interior and compact folding when empty is also a major plus. Overall, this waterproof duffel bag is a great investment for anyone needing a reliable and high-quality bag for any weather condition. Highly recommend it.

Great water proofing

Bought this bag a month ago and used it on a 3 day portage in Algonquin Park. We had wet weather for the first two days and it kept my gear dry. If you are packing something lofty like a sleeping bag ensure you use the tie down straps inside or the zipper can open with enough direct pressure (leaning on it in behind me while steering). Great bag!

Good but not great

This is a good waterproof bag made from outstanding materials. I removed one star because there should be zip tabs at each end of the zipper to help opening and closing the bag. Once the zipper is moving it is very smooth. The zipper hold-tabs would be helpful and give you a place to grab the bag. The shoulder pads seem to be a notch below the quality of the rest of the duffle bag. Otherwise I’m very happy with it.

HW DUFFEL--Where Have You Been All My Life...

I recently purchased the High Water Duffel from Mystery Ranch. I had been looking for a mid-size waterproof duffel to carry expensive gear in the bed of my pick-up. The truck's hard bed cover is lockable but not waterproof. I had tried other brands but was never satisfied so I returned them. I've owned a Mystery Ranch Three-Day Assault bag for years and use it every day so when I saw that the company had introduced a 50 liter waterproof duffel I ordered one. The bag more than meets my requirements. The giant central compartment swallows as much gear as I shove into the dry-zipper opening. The dry-zipper functions smoothly every time with no snags. Per MR,s recommendation I applied zipper wax. I utilized the dry zipper wax crayon that I use for my SCUBA dry-suit zipper. The High Water Duffel's main compartment is 100% waterproof, and has been severely tested in the short time that I've owned it. The bag rode in the bed of my truck during a week long, wind-driven rain-filled Northern California road trip. The following week I used it during two days of outdoor range training occurring in continuous heavy rain and wind in Los Angeles. On both occasions the exterior of the bag was completely wet while the interior compartment and contents remained bone dry. But the waterproof exterior fabric quickly wiped dry with a towel. I like that the bag has minimal organization, which allows it to accommodate multiple large, bulky items. As my rapid deployment bag, it is currently holding both soft body armor and a hard rifle plate carrier, gun belt, holster, pistol and rifle magazines, IFAK, helmet, and light breaching tools, There is still room remaining for a jacket, combat pants and boots. The bag has two exterior mesh zippered pockets--the bag's only organization--which is perfect for smaller items such as chem-lights, markers, flashlight, goggles, waterproof notebook, and a thirty-foot nylon strap. There are four external daisy-chain attachment points running perpendicular to the long axis. I have a carabiner attached which holds door wedges. The bag can be carried as either a backpack or a traditional duffel bag. It comes with two quick detachable padded shoulder straps that can be reconfigured as a single duffle strap. There are also two reinforced carry handles on either end. I couldn't be happier with this purchase. I'm actually considering buying a second High Water Duffel to carry clothing and other items on long road trips and/or to carry dry items on the deck of an operational dive boat. Mystery Ranch hit it out of the park with this one.

A sturdy waterproof duffle suited for Overload

I've owned this for about two months and am overall happy with it. There is a lot of utility with a waterproof duffel and the dimensions of this one (longer, broader, and flatter than most) that make it ideal for Mystery Ranch's Overload system was the main selling point. Durable: I'm confident the material will take a beating. I drop it wherever is convenient. Comfortable: The handles on each end are great for shuttling the pack short distances. The backpack straps are more comfortable than I would have guessed. I thought I would miss the handle in the middle of the duffel or a wrap to link the backpack straps, but I haven't. Simple: There aren't many bells are whistles. The only thing inside are two compression straps, no pockets. I kind of wish there were a couple pockets on either end/side. You have the mesh ones on the outside, but obviously there not waterproof. There isn't a flap, so when you open the bag it remains mostly closed. Once you get the zipper going, it's smooth, but I do wish there were pull tabs on either end of the zipper to hold on while you pull the zipper open and closed. It's not necessary, because it's a straight pull for the "Tru" zipper, but the tabs would make a better experience. Or

Impeccable design. Keeps gear dry.

I purchased this bag for a general purpose dump bag for my raft for fishing/hunting season in SW Montana. Its first use was on a late season float hunt where it spit rain and snow on us. We also piled 2 deer into the boat on top of it by the end of the day. My gear was clean and dry inside despite the conditions outside. Highly recommend.
