Backcountry 40L Duffle/Pack (V2.0

A awesome well made piece of gear,
I would give it 5 stars except the tent pole pocket is to small for most all tent poles, Yes i tested with 5 different brands. I would suggest a flap opening on each end with the quick connectors to accomodate larger size tent poles, same goes for the 30L bag.

They really thought of everything

The way this bag is built just makes packing and planning easier. Love the dual openings so the middle of the bag becomes the bottom - so much easier to decide what goes in at what time as both sides get you what you need fast. That plus the bomb proof construction, easy to secure, and the backpack straps if it all goes to heck make this a no brainer item for every trip I go on.

Love this heavy duty gear.

I recently got the back country 40 L duffel and the back country 30 L duffel, along with the Nomax tank bag. The fine folks at Mosko Moto did some amazing research and development and really thought through the needs of people that like to spend time in the saddle. The stuff is amazingly bulletproof. Prior to ordering this gear, I had just got done with a six week 10,000 mile coast to coast trip on my BMW R 1200 GS. That trip managed to finally wear out my former, worn out, and tired, leaky, duffel packing system. I can’t wait to take a good long trip with my new gear. My only beef with Mosko Moto is that the don’t have riding clothes that will fit my 6’5” husky body. However, I did get some outstanding riding pants for my wife. Mosko Moto has been a pleasure to deal with. You will be pleased with anything that comes from Mosko Moto. And I can’t wait for the R&D folks to develop larger riding attire. When the do, I will be the first to order some new and updated threads. MM ROCKS!!!

Responding to Mosko's description of the item I would say they succeeded in being different from the usual waterproof tail duffle. Not in a way that is better or smarter though in my opinion. The double ended opening is a fail IMO because it requires you pretty much pack it from both sides or risk having a very asymmetric load if you roll one side closed before packing. Difficult at best to try to even up a load by opening both sides and pushing the bag contents over to the other side. If both sides of the bag are open when empty it wants to default to a flat shape which is an interesting hurdle.
They mention the side openings being an advantage over top openings because your mounting straps won't block the openings..In practice you can't load this bag with your straps cinched anyways so they must be loosened and now the direction you're loading the bag wants to push it off the side of the motorcycle, so guess what, you're taking this off the bike to load it if you're really cramming gear into it. At least a conventional top opening can kind of balance on the bike and the bike serves as a platform for cramming stuff down into a bag.
The angled straps that go to the edges of the roll closure impede the beavertail laying flat open unless they're barely rolled at which point the waterproof-ness seems suspect. The waterproof liner would be a good candidate for having its own closure so that you could roll it up securely and independently of the outer material like they have on the liners for the backcountry panniers. It would be even more useful on this bag because then you could pack the liner, roll it up and then center it by just pushing the whole bundle over to one side or the other more easily. As it is, they have it where the liner just velcros to the lip of the outer and they roll up together. Also, on my bag it seems like the OD of the waterproof liner is larger than the ID of the outer bag, so there's always some bunched material on the liner which makes it even more difficult to pack and ultimately wastes some capacity.
This bag has a lot going on, lots of buckles and straps and closures and all in all it's just a very busy bag with an answer for everything, but in a way that feels half-baked to me. The usual rubber duffle bags may be simple and only do one thing, but they do it well for relatively cheap and this duffle does 20 things, none of them well, and for 300 american doll hairs.
A good analogy is one of those swiss army knives that's like 3 inches thick so even if you just want to cut open a box you have to contend with 50 other questionable implements.

Backcountry 40L Duffle/Pack (V2.0)

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. Pair it with our Backcountry Cinch Straps for rock-solid attachment to your bike. The newly updated 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 are two nylon reinforced mesh pockets 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 30/50 duffle if that’s the way you’re leaning.

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.
