Fatty Tool Roll

Roll a Fatty with the Fatty Tool Roll! It fits everything you need for an extended ADV trip, plus packable tire irons, tube patches, and more. There are two handy zippered catchall pockets for oddly shaped items like Loctite and JB Weld, or larger tools like an adjustable wrench. Everything rolls up into a waterproof cover, so you can store the Fatty outside your luggage and all your tools will stay bone dry.

When we first investigated tool storage solutions several years ago, we were initially turned off by the 'roll,' even though we were all using them. A tool roll seems so old-school, like something a cowboy would've carried, or a biker gang in the 50s. Surely there's a better, more modern way?

With more research though, we came around. There's a reason why tool rolls persist. The beauty of a roll versus, say, a bag or box, is that it naturally expands and contracts based on how much stuff is in it, and it conforms to a wide variety of tool shapes and sizes, while still rolling into a tidy package that fits in a stash-spot or external pocket.

With tool rolls, we felt there'd been a 'race to the bottom' on price-point and features. There are so many tool rolls already on the market, all with very similar features, and all at the lowest possible prices. Many OEMs even ship a tool roll for free with every bike. So we went a different direction in designing the Fatty and Pinner. We cut zero corners on materials and features, and we hope we created the most awesome tool roll you'll ever own.

Is there another waterproof tool roll out there? If so, we haven't seen it. The Fatty & Pinner come with highly abrasion-proof, welded-seam, waterproof rain covers. Tools are heavy and hard, and they press and vibrate against everything they touch, so the rain cover's gotta' be tough. This one is tough as nails, and it doubles as a trailside parts tray. If you're riding in the desert and don't need the raincover, no problem: reduce bulk by leaving the raincover at home and taking only the tool roll itself.

Sliding the roll out of the raincover, you'll see lots of tool storage pockets, with webbing straps to hold everything. Unlike traditional tool rolls, however, there's also a large Velcro flap that traps your tools in place, so your tiniest hex key won't escape somewhere out in the woods. Inside the flap there's a zippered mesh pocket for tube patches and tire repair. On the outside of the Fatty, there's three long pockets for tire irons, which are always kind of a hassle to store.

What about those bulky tools that never fit? Things like vice grips and open-ended wrenches? We added two large zipper pockets to accommodate these, plus spark plugs, JB Weld, sockets, Loctite, and all those other things which you always need but can't find, because they're somewhere in the bottom of your bag. Next to the two large zipper pockets, we added a clear zipper pocket for documents, an air gauge, or anything else you want to tuck away. It even has a conversion table printed on the front, plus a recipe for our favorite trailside drink: the Mosko Mule.

    "After searching all over for a tool carrier that can organize big tools and small parts alike, a friend sent me to Mosko. The Fatty is just perfect. Large tools and small, spare parts, and MacGyver gizmos all have a place. The waterproof bag makes it indispensable. It holds a big tool kit and bundles up right. The lash strap loops let me tie it when there's no room to stow it. One of a kind kit!"

    Fatty tool roll

    Well well made, has plenty of storage for tools and set up nice. I hope the waterproof bag keeps my tools dry.

    Phenomenal products

    I previously purchased the Pinner, which I’ve taken on several week+ trips and typically have with me on all rides. I love the Pinner, although I keep tire irons and a couple other things separate from the Pinner, although I could roll them up in the Pinner. I wanted a second tool roll, just so I don’t need to keep switching one roll between bikes, so I figured I would get the Fatty to compare. It’s the same stellar quality construction (as all of their stuff). I envision using my Pinner with my 250 and 350 dual sports normally, the Fatty on my bigger bike, where the additional bulk doesn’t matter as much. When I finally quit my job and go on a multi-month trip, I’ll probably take the Fatty, regardless of which bike I choose.

    Works like magic

    to tell you the truth, this fatty tool bag is my 3rd product from mosko. i dont put high expectation since your built quality, aesthetic & functionality way higher than mine. on the product, it have all the pockets that i need to put my tools for my this february trip to saudi, uae & oman. even i haven't test it, i'm pretty sure it will survive my 2 weeks in various conditions. FYI, i will bring along 3 mosko products (scout 25 pannier bag, nomad tank bag & fatty tools), will post some photos to your facebook page.

    thanks for making good, functional, reliable & beautiful products..keep up the good work. we will keep on supporting you guys.

    First Time & Very Satisfied Customer

    Our son was introduced to MoskoMoto on one of his adventure rides last summer. He spoke so highly of the people and the product that we made a note of it for our Christmas shopping. The processing of our order from initial placement to fulfillment was excellent. We were kept informed of shipping dates and progress. Before we wrapped the tool roll and put it under the tree I had a look at the product which appears to be indestructible and well thought out (we had looked at similar products at local dealerships so had an idea of what was available on the market). Overall a very good experience.
