Nomad Tank Bag

Inspired by the hydration packs we use for backcountry skiing and mountain biking, we set out to design a completely different kind of tank bag. The Nomad comes with a 1.5L hydration reservoir, and it has tons of pockets for all those little things you used to throw in a tank bag and promptly lose. Best of all, it unclips from the bike quickly and easily, and converts to a fully functional backpack.

After talking to hundreds of riders around the world, and combining that input with our own personal wants and needs, we decided that, rather than start with a traditional 'toaster' shape, we would divide the Nomad's space into six vertical layers, each with its own specific mission. We compiled a massive list of the things people store in their tank bags and found the majority of the items on the list were very small. A vertical layout maximizes the utilization of space without making the bag too tall.

The top layer of the Nomad features three columns of MOLLE webbing, which can be used to mount an included rain-proof map pocket, or other MOLLE-compatible items that you might want quick access to. For example, it's a great place to store a MOLLE-compatible multi-tool, fixed blade knife, or protective cell phone holder. MOLLE webbing enables you to customize the rider-facing top layer of the Nomad to suit your individual travel style. Some riders like a map pocket, some riders don't.

Below the MOLLE webbing, the next layer is an expandable beavertail. If you already have some of our other bags, then you know just how handy a beavertail can be. On the Nomad, the beavertail serves as a quick-stash spot for things like sunglasses, gloves, snacks, or even a small DSLR camera. If you use it for your DSLR, we provided webbing loops on the beavertail side bellows, so you can clip the D-rings on your camera case directly to the bag. Inside of the beavertail we added a pocket for a Delorme InReach or SPOT beacon, and there's even a gated clip to hold your GPS/camera/InReach lanyards so nothing tumbles out when the bike goes down.

The third layer zips back into your lap, and is specifically designed for small-item organization: things like charging cables, pens, change, batteries, earplugs, chapstick, passport, and bike documents. There are six mesh pockets, three elastic cable holders, two pen holders, and a fleece-lined glasses pocket. No more tangled soup of miscellaneous items floating around in the bottom of your tank bag, everything has a home.

The next layer is a large open compartment, featuring plenty of space for bulkier items like extra maps, spare gloves, wallet, CCW, and food. There are two large mesh pockets (one with side-walls and one flat), which are available if you need them, but compress out of the way if you don't. Also, for contact lens wearers, on the foam-reinforced sidewall there's a removable lens case holder, which can be rotated to keep the cases vertical depending on the orientation of the bag.

Under the main compartment, accessible from a pocket at the bottom of the bag, there's a long, flat pocket that accommodates a 1.8L Platypus hydration reservoir, which is included with the bag. In warmer climates and on long distance trips, it's really nice to relocate the weight of your drinking water from your back to the tank. If you'd rather keep the Nomad as tight as possible to the bike, and/or if you'd like to maximize space in the main compartment, you can remove the reservoir and store it elsewhere on the bike. With the hydration reservoir removed, there's a large patch of hook/loop Velcro in this pocket, which is also a convenient spot for a CCW.

The sixth and final layer of the Nomad houses a quick-stash spot for two sewn-on, crushable backpack straps. Simply un-clip the Nomad from the bike, pull out the backpack straps, clip them to the D-rings at the bottom of the bag, and the Nomad converts into a fully functioning hydration pack. The side straps, which normally connect the Nomad to the bike, now become your waist strap. We use these backpack straps on dualsport trips all the time, from morning hikes to running errands around town. And the best part is that the Nomad doesn't look or feel like a 'tank bag on your back.' It looks and feels like a real backpack.

The Nomad includes a waterproof rain cover, with a welded-seam top panel and sealed seams on the side, to keep all your belongings dry even in a heavy downpour. There's a stash-spot for the rain cover on the top of the bag, and a clip to keep it connected to the Nomad so it doesn't get lost.

After two years of work, and so much input from the riding community, we've tried our best to design the ultimate adventure touring tank bag. We hope you agree!


- Due to the Nomad's long torso, it may not fit on smaller bikes or bikes without a front gas tank. This is a brand new bag, so we'll be learning a lot about which bikes it fits on and which it doesn't.

- We specifically designed the Nomad to sit much farther forward on the bike than a typical tank bag. It's not uncommon for the top of the bag to extend over the handlebars on some bikes. We recommend rigging it as far forward as possible.

- The Nomad expands & contracts as needed. If you prefer a tight fitting tank bag with a low profile, remove the hydration reservoir and map pocket, and cinch it down tight to the bike. For more capacity, take full advantage of the beavertail.

    Nomad Tank Bag

    Purchased this bag for a trip to Colorado and Utah coming up, I really like the inclusion of the water bladder, multiple pockets, and backpack straps. Did some gnarly greasy off road riding this weekend and it was great, encountered some rain on the ride home and threw on the rain cover, with phone, chargers, and wallet inside all staying dry. Very pleased with the build quality and attention to detail. Thank you Mosko Moto for some awesome gear.

    Mosko Nomad Tank Bag

    The Nomad Tank Bag is simply the best tank bag I have ever owned. Background, 2017 KTM 1090R, purchased 2018, June 15, 14,000 klm, Adventure Rides, British Columbia, Alberta, Baja Mexico, Arizona. The compartmentalized structure of the bag, water bladder, results in it being the most accommodating bag I have ever owned. The quality of construction is light years ahead of competitors. My life just got a whole lot easier and organized since purchasing this bag. Ordering was easy and delivery to Canada was within 7 days. If you are a serious Adventure this bag is a must have.

    Great design, fits well and easily carried

    The bag works great. I like the method of organization, by introducing layers. Had a blast figuring out what to put in each section. Items are so easy to find since they’re organized. Fits really well on the bike, I ride a BMW R1250 GSA. It turns very easily into a backpack to carry around. Though I do wish the backpack straps had some kind of rubber coating. Single shoulder carrying can be difficult. I’m sure the materials are extremely strong, but not as high-quality as some of the camera bags I own. The sheen on the fabric is the giveaway. It seems well-made, I doubt there will be any problems. All in all I’m very happy. Four stars because of the shoulder strap and the generic textile choice. No brand tags usually mean a generic fabric; not an issue just an observation. Would definitely buy it again.

    Nomad for the win!

    I’ve had this tank bag for a couple weeks now and it’s been great. The different compartments for organizing really allow you to keep items divided up into groups so you know exactly where they are. The easy open beaver tail w/molle webbing and extra storage underneath may be my favorite part. The extra water storage is genius too. The only hesitation I had before purchase was the fact it’s not waterproof, but the included rain cover is so quick and easy to put on and the pocket it’s stored in is plenty big so it doesn’t take meticulous folding to put it away. Overall, it’s been AWESOME so far.

    Backcountry panniers and duffle
