The go anywhere, do anything gear you need. ![User picture]()
After years of using my Mosko Nomax tank bag with little to no wear, I knew Mosko was the way to go for my tail bag. I travel the country visiting motorcycle training ranges for a living, and I need to look professional when I get there. The last two weeks were spent traveling from Chicago to Denver, and then turning around to go to Pennsylvania and back to Chicago. The whole time, the Nomax kept my riding needs covered, and the Alpine Duffel with the straps was simple to take off and carry into each hotel. When I arrived at each site, the bags complemented the bike nicely, with everything looking great. Riding through the Rockies one week and the Appalachians the next was great; everything stayed in place, and everything I needed was quickly at hand. If I have to fly in and ride somewhere, the Alpine bag can be checked or carried on, and strapped down securely to just about any bike. If you need your gear protected and looking great, Mosko Moto is the way to go.

Alpine 50 Duffle 3k miles later
I bought my wife and I both the same duffle for the back of our Africa Twins. We’ve did a 3k mile Pacific Northwest trip that consisted of 70/30 riding. This duffle worked so well! All our camping and sleeping gear and whatever forgettable got stuffed inside. Well built and with all the tie down options this duffle was indispensable.
