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 was the Only Choice

DES and I are motorcycle hammock campers: you can see our absorbing, enjoyable hobby at . DES is also taking a wrenching class at a local Technical Institute, and I wanted to pick him up some tools and a kit for his birthday. You have to understand: DES researches and tests everything, and only the Fatty would do. It carries everything he requires, it rolls down nicely to fit in the back pocket of the Mosko Reckless, and it's even got a weatherproof sleeve. We'll probably feature it on our blog at some point: he's really happy with it. Good one, Mosko!

Excellent tool roll

This high quality roll is a perfect fit for a very well stocked set of tools. It’s a bit stiff right out of the box but will probably soften up and certainly appears indestructible. I especially like the handle and the very secure velcro closure. Because of its capacity, it can lead you into taking too much stuff but, unless I loose it, this will be my last tool roll.
Highly recommended!

Tool Roll

Got a quality tool roll that I’ve been looking for for two years. This is it. Bought it at the Van M/C show and it was at my mailbox within a week as promised. Great Service good quality.
Also we used their soft luggage on a ride in Ecuador. There were other brands on other bikes but the Mosko gear was hands down the favorite



Michaels Fatty Tool Roll Review

When i packed the fatty the first time I was very confused about how to organise my tools with it. I had to rethink my toolkit a little bit. I never used sockets and bits before because you loose them in classic tool rolls. With the fatty i could do that and safe weight and space. My toolkit was already lean and i noticed after optimising my tools for the fatty a pinner tool roll would have been enough too. I'm really looking forward to test it on the road now. I don't expect that the durable tool roll will let me down I'm mor curious on how i like the new organisation.
