The Alpine Duffle is a lightweight, 100% waterproof roll-top dry bag for enduro-touring and adventure motorcycles. This premium tail bag comes in two sizes: 50 liters and 30 liters.
Universally mounting to any motorcycle tail rack with our optional Alpine Cinch Straps, the Alpine Duffle complements rack-mounted panniers with additional storage in a minimalist design package. Pair with our Alpine Pannier Kit for a lightweight, high-capacity adventure touring setup designed to prioritize weight-saving performance in technical terrain.
It features a wide opening and an easy-access roll-top design, providing ample room to access your packed gear. Constructed from 100% waterproof DWR-coated 420D nylon 66 ripstop and 840D TPU-coated nylon fabric, the Alpine Duffle is robust yet lightweight, with reinforced ends and bottom for added abrasion resistance. The unique beavertail design has reinforced mesh zipper pockets on one side and five columns of Hypalon MOLLE webbing on the other, allowing expansion and customization with an assortment of optional MOLLE accessories.
The Alpine Duffle's beavertail features premium anodized aluminum Atlas buckles, commonly found on avalanche airbag backpacks. This simple yet tough buckle design is easy to open, latch, and adjust with riding gloves on. The durable aluminum construction withstands the abuses of offroad travel, and is less likely to break and need repair like plastic buckles.
The beavertail provides a convenient place to tuck a jacket during the day or to store wet or dirty items, such as a rainfly, tarp, or towel. The integrated backpack straps deploy quickly and easily, allowing you to carry the duffle through airports for fly-to-ride trips or to pack your gear into campsites and hotel rooms on trips. When not in use, the backpack straps stash flat in an external pocket or can be removed entirely and left at home.
Two easy-grab carry handles provide options for hauling, loading, and unloading the duffle in travel scenarios.
The Alpine Duffle can be universally mounted on any tail rack via cinch straps to securely loop through multiple pass-throughs on each side of the bag, ensuring secure retention. The nylon pass-through loops allow the duffle to stay securely attached in rougher terrain that can cause some tailbags to squeeze out of their straps.

Constructed from 100% waterproof DWR-coated 420D nylon 66 ripstop and 840D TPU-coated nylon fabric, the roll-top design keeps your gear bone dry in harsh conditions.

Rolltop duffle design is compatible with most tail racks, universally mounting with our optional Alpine Cinch straps.

Removable beavertail provides packing options, giving riders the ability to stash wet gear, strap down jackets or rain layers, attach MOLLE accessories for additional storage, or remove it altogether to prioritize weight savings and ride performance.

Deployable/removable backpack straps provide a simple, comfortable carry option for days spent trekking through airports on fly-to-ride trips, or when packing gear in from bikes to hotel rooms. Simply remove the backpack straps altogether if not used.

The Alpine 50L Duffle, is large enough to secure all of my light camping gear while I ride. It is also waterproof, and though I have not needed that feature just yet it is nice to have. I purchased the straps as well to secure the Alpine duffle and they work perfectly. Easy to attach and secure. Moskomoto is the best gear on the market, and this product is no exception.
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.
I picked up the Alpine 50L to replace a different backseat bag I had. The build quality and materials are top tier. The buckles are heavy duty and easy to use and the beavertail feature makes stashing your jacket quick when you want to do that.
I rode through a storm that ended up spawning several tornadoes later in the day. 6100 miles, 14 states, 9 days, nothing got into or even phased this bag.
Purchased the bag for a trip to Costa Rica, worked great on the plane and on the bike. Well designed, tough, easy to use and secure to the rack, never had to worry. Look forward to using it again.
I purchased the Alpine Panniers and Alpine 50L Duffle recently, even thought I own MM Backcountry 35L Panniers and Scout 50L Duffle. Wanted to try a slightly more minimalist set (the pannier system). Returned today, Saturday, from a 6days/5nights, 1600 miles moto-camping trip in Arizona (where I live) and New Mexico, USA. The Alpine Duffle is a liitle easier to fold up compared to the earlier Scout version and matches with the panniers in material and design. Mosko Moto have designed a good product as usual. In the photo the duffle is unloaded but I secured it to the bike instead of leaving it on the ground for fear a coyote might drag it off at night thinking there was food inside.
