Scout 25L Duffle

The Scout 25 Duffle is a single-layer, welded-seam, roll-top drybag. We loaded it with every moto-specific feature we could think of. It quickly converts to a comfortable backpack, complete with padded shoulder straps, internal stiffener, waist belt, and sternum strap. It also includes a handy beavertail stash spot, and a 20L laundry bag. The Scout 25 works great as a standalone tailbag, a travel bag, or a pannier topper on hard boxes.

The Scout 25 is a welded-seam roll-top drybag designed to be mounted on a rear luggage rack or as a topper for hard-sided panniers and/or top boxes. The backpack straps are handy if you breakdown and need to hike out, or when navigating an airport or border crossing on fly-to-ride trips. They're also handy when you need to get all your gear to an upstairs hotel room in a single trip. The backpack straps stash flat in an external pocket, and clip to two d-rings on the bottom of the bag.

The Scout 25 Duffle includes a unique beavertail with a waterproof map pocket on one side and 5 columns of MOLLE webbing on the other, so you can expand and customize this bag with an assortment of optional MOLLE accessories like fuel bottle holders or a hydration sleeve. The beavertail also provides a convenient place to tuck a jacket during the day, or to store wet/dirty things like a rainfly, tarp, or towel.

The Scout 25 has side cinch strap pass-throughs (we recommend our Backcountry Cinch Strap) so you don't have to worry about your bag squeezing out to the side of the bike in bumpy terrain. There's an internal stiffener to prevent it from drooping over the side of your bike and burning on the exhaust. The Scout includes a comfortable, padded shoulder strap that stashes away under the beavertail when it's not in use. There are two comfortable, padded carry handles at the ends of the bag, and two webbing handles on the side.

The Scout Duffle also includes a 20L seam-sealed Drysak, so you can keep dirty/damp clothing, shoes, and other items separate from the rest of your clean/dry belongings. It also has two internal end-pockets with velcro flap closures for storing small items like a headlamp or toothbrush.

Want to protect your Scout Duffle and gear from thieves? Add one of our Steelcore Locking Straps. The Scout Duffles (both sizes) require a single 1.4 m strap. Mounting instructions can be found in this video.

    Product Creation at Mosko is an effort born of necessity. Everyone on our team rides – and time on the trail translates to an innovative, always improving product line. Crafting gear that will outperform in even the most harsh riding conditions means we make no compromise, ever.

    "This bag is great! I use it as a tailbag on my 1090 on top of an AltRider Rear Luggage rack and it's a perfect fit! It's the perfect size to hold darn near everything I need for a ride into work or an overnighter into the forest. Super well built, dry (and that's important in the PNW) and as a bonus - it works great for a backrest when loaded up for my pillion! This bag checks all the boxes and then some. Get one!"

    Beast of a bag

    I love this duffel and use it on every moto trip. Great carry-on with both back pack and single shoulder strap. Voluminous single pouch holds everything I need as I am a lumper not a splitter. I don’t use the map pouch much but it’s a handy extra for anything I’d like to see or hold for rapid access on top of the bag. Lots of jealousy from other riders when I show up with the Scout Dufffel.

    Great Product

    I purchased the 25L duffel to use as an add-on to my existing set-up, it has worked great!, I absolutely love it. The 2 main things I like are the quality of the product itself, and the versatility, seems like Mosko though of everything, wherever I think it will be a good idea to have a strap, loop or pocket there is one already. Highly recommended. Planning on purchasing more of their products in the future.

    Scout 25 for the win.

    Once again I am super stoked opening up the box from Mosko. Bought the Scout 25 duffle to accompany my Scout 25 soft bags... will never buy another brand of luggage as long as I ride... quality and customer service can not be beaten.

    Perfect size for me

    Prior to buying the Scout 25 I had a small tail bag from another well known manufacturer. I mostly do day trips and like to keep my bike (2019 KTM 790 Adventure R) pretty light and minimalist. The other tail bag had just enough for a some tools and essentials, but didn’t have much expandability for carrying a jacket or if I needed to pack a lunch, etc. Additionally, the other bag required you to put items that you didn’t want to get wet in a separate wet sack.

    The Scout 25 works perfect for me because it compresses down real small if you don’t have much in it, but expands nicely for additional items. In addition, the beaver tail works great for stashing a jacket or other items that don’t need to go inside the duffle for easy access. In addition there’s no need for a separate wet sack to keep items dry in the duffle.

    I’m super happy with this setup along with the backcountry cinch straps and the steel core locking strap to keep things secure when out and about.

    Latest 25 l scout Tail Bag

    I had the original bag which developed embrittlement in lower corners and actually started tearing ... I am so impressed by the Mosko team who replaced the bag without me even asking .. i just wanted Mosko to know about it for product development .. in fact the new bag I received is a lot more flexible and pliable with an obviously new grade in water proofing material .. the service is fantastic and I have had bag on a trip and it has proven to be physically improved.. thanks Mosko team for considering your customer and more importantly, getting your product fit for longevity purpose.
    Just a 4 star because I want to see how it is in a couple years from now .. otherwise a 5 starr
