SW-MOTECH Drybag 180 Tail Bag Roll-Top Waterproof Dry Bag | 18L

Pick this up to strap on my trunk lid. Very nice, stayed in place, even with some spirited riding. Weather was nice, so I can’t comment on how water proof it is yet.

I bought this bag as a supplement to go on top of my SW Motech Drybab 350 which is arguably the ideal size and shape to fit on most touring and adventure bikes . The amount of camping gear I took had some items which did not fit well in the larger bag so this one was used to supplement that need. The bag is really small and sat on top and would work nicely on most bikes without a top box but it was more aggravation that help in my case so I folded it up and put it in the bigger bag and will use it again I’m sure but in this case it was not a good fit. the combination of the two bags on a sport touring bike with top box ended up shoving my crotch into the tank and after six thousand miles of that discomfort I caved in and folded it up . Less is more and the two stackable bags are still a great idea but not on my bike .

This is just the right size to supplement storage and the strap placement makes for a perfect attachment to top cases. I have GIVI Dolomiti and their attachment points look custom built for this bag.
