Backcountry 30L Duffle/Pack


This moto-duffle does it all: it's a duffle, a backpack, and a quick-stash spot during the day. It's a way to keep your wet jacket separate from your dry sleeping bag. It serves as a clean food prep surface next to the campfire and a convenient tool tray for roadside field repairs. The Backcountry Duffle is available in two sizes, a 40L version and a 30L version.

People have been strapping all kinds of miscellaneous duffles to the back of their bikes since motorcycles were invented. Do a quick google search for ‘waterproof motorcycle duffle’ and you’ll see what I mean. The same basic welded seam waterproof roll-top duffle is presented a hundred times over, with different logos. It turns out that when you start from scratch and ask the question ‘how should an ADV duffle function’ you end up with something that looks and functions a lot different.

With the Backcountry Duffle we wanted to design a motorcycle bag from the ground up, instead of starting with a kayak/rafting drybag. Two things jumped out at us right away. First, we hated having to unpack the entire back of the bike just to put something in or take it out. If you picture a traditional roll-top duffle, the straps that connect it to the bike are going over the opening, which means that you have to undo the straps to get inside. Plus, because the bag is sitting on the back of the bike, by the time you unroll the opening it is too high to see inside. So you take it off the bike and set it on the ground. If you’re getting in and out of the bag several times a day this starts to get pretty annoying.

Second, traditional single-layer drybag duffles have a very limited lifespan. There are so many things that can cause them to fail. Campfire sparks, abrasion from a crash, abrasion from the rack it sits on, heat from the exhaust, cracks from sun damage, etc. As soon as anything happens to the bag, it’s not waterproof anymore. And if that happens in the middle of a trip it sucks.

We came up with the idea of a bag that’s actually two bags – an inner waterproof bag and an outer abrasion-proof bag – to solve that problem. Then we made it a double-ended roll top instead of a top-loader, so you can get things in and out without unstrapping it from the bike. Then we added a beavertail on top of that, so if you need to stash your jacket, or wet/dirty items that you don’t want inside the drybag, these things can be stored externally without getting inside the duffle at all.

Then we added backpack straps. Riding 50+ miles on dirt is no big deal on an adventure bike, but if you break down and find yourself hiking out, it’s a long friggin way man. Having a comfortable backpack is key. That was the original idea behind the backpack straps, but it turns out it’s also super handy for getting everything into (or up to) a hotel room in a single trip. When you’re traveling internationally, sometimes it’s not ok to leave half your stuff on the bike while you take the other half inside. With the BC 30/40, put the duffle on your back, grab a pannier in each hand, and you’re mobile. Plus the straps make it a great airline carry-on for fly-in trips or general travel.

Inside the beavertails there's a mesh pocket for wet/dry items (like a toothbrush), a document pocket which works great for maps, or for your bike documents and passport. The document pocket is especially helpful at border crossings where you have to stop at multiple customs offices on both sides of the border. Remove the document pocket, take it inside the customs office with you, then when you're done put it back inside the beavertail and ride over to the next office. That way you can collect all the country specific paperwork in a specific spot. Also under the beavertail there's a special tent pole pocket so you can split your tent into its various components, making it so much easier to pack. The tent pole pocket also works great for a camp chair, fuel bottles, a fishing pole, etc.

There are two things that take some getting used to on this duffle. First, the materials are really thick, which means that rolling/unrolling the roll-top feels a little cumbersome at first if you’re used to thinner kayak drybags or stuff sacks. The materials loosen up with time, have no fear. Second, compared to a top-loader, the double ended roll-top has a narrower throat. So when you’re in your tent, or in your hotel room, sorting through the stuff inside is not as easy as it would be with a top-loader. We make top-loaders too, check out our Scout 25/60 duffle if that’s the way you’re leaning.

The Backcountry Duffle also includes a separate 20L Drysak bag, which can be used to keep dirty/wet items (like shoes or towels) separate from your other belongings. 

Want to protect your gear from thieves? Add our Steelcore Locking Straps. The Backcountry Duffle requires one 6' strap. Mounting instructions can be found in this video.

Connection Strap Note: For pavement and graded road riding, virtually any kind of connection strap will work to attach this duffle to the bike. For rough, ungraded terrain or for long-distance, multi-month trips, we highly recommend the Backcountry Cinch Strap, which was designed specifically for this bag and this kind of travel. Whatever strap you choose, if you will be riding offroad, please avoid bungy cords, stretchable elastic straps, or straps with plastic side-release buckles. Even a simple cam buckle strap (like this one by DaKine) is better than elastic.

    Lovin' my Backcountry 40

    Although I haven't had the Backcountry 40L bag long, so far so good.

    As with all Mosko products, this bag is definitely made from durable materials. It's so much more than a dry bag. There's a lot of creative storage options. I've already used it as a backpack.

    Very well thought out bag that I know will last me many adventures.

    Great product and fantastic customer service.

    Well over 137,000 kilometers of use

    I am now in my fourth year riding around the world on my motorcycle. Been to nearly ninety countries. My favourite piece of luggage is my 40-litre Mosko Moto (“MM”) duffle bag, the only MM luggage I carry. I used the duffle bag as an overnight bag and took it on and off the bike almost every day. I am just about to install my third set of Roc Straps, which are not as hardy as the duffle bag, but still good. I think of this MM duffle bag as being three bags in one. First, a strong waterproof bag that straps extremely securely onto my bike (make sure you do not overfill the bag and roll the dry sack such that it is face down when it raining). Second, it is an extremely uncomfortable backpack that I have trekked hundreds of kilometres with. When you are riding around the word on a motorcycle you have no room for a backpack, so this will do you just fine. The strap that links the two shoulder straps at the front broke early on - that strap is an important strap that makes trekking a little more comfortable, so I was bummed it broke. Finally, it is a duffle bag to carry on ships, ferries, planes buses etc. whenever I have to part with my bike for whatever reason. My father passed away on my trip and I had to fly halfway across the world - the MM duffle was my checked luggage. Once, one important male/female strap connection broke when it was manhandled off a bus. I managed to tie that strap such that I mainly used just one end of the bag. Transport baggage handling people unfamiliar with the duffle bag tend to grab at any straps they see just to haul it, so keep straps as tight as possible. The duffle bag is a magnet for dust when off-road riding. Fortunately, when you take out the dry sack the outer bag washes well at a launderette. My duffle bag has been washed many times. These are the only problems I have had with the duffle bag in over three years, tens of thousands of miles and daily use. Buy this duffle bag – in my opinion, there is nothing better!

    Hard to get better than this

    Mosko moto has designed a duffle that checks all the boxes, The more I use this duffle the more I appreciate the field testing they have done to ensure their products survive the harsh conditions that some of us put on our motorcycles and luggage. Keep up the good work. Picture is from the day I received the luggage.

    #1 Go-to pack

    I got the 40L Backcountry duffle almost 6 years ago. At first it was just my pack on my bike. After using this amazing pack it has become my go-to travel pack for bike, backpacking, or just traveling. It has been with me now on the bike through about 40 countries, and several more without the bike. I use it on a plane as my carry-on and have never been questioned. It has kept my stuff dry through snow and rain, sometimes for multiple days. I don't go anywhere without it. Thanks MoskoMoto for getting overland travel and making gear that can withstand the tortures we can put our great though.

    Excellent Quality Kit

    Currently prepping my bike but have to say the quality of the kit and the thought that has gone into it is awesome. There are so many great features, it shows that these have been designed by those who have walked the walk!!

    Had an initial glitch on the order due to a mistake made by myself, but was sorted quickly by the team.

    Not the cheapest but the quality and functionality more than makes up for that.

    Looking forward to testing these out on the trails later this year!
