SW-Motech Legend tailpack 48 litre

Fits on anything easily with straps provided and grippy bottom helps it stay in place. Lots of room inside, but strange shape means you seem to fill it quickly! ‘Splash-proof’ waxed material, so should be alright and there is a drybag shaped for inside if it gets worse. Side pockets useful and you can add things like our drinks holders to the Molle-style loops. Well made, fits on my BMW, Maria’s Enfield or my BSA, so pretty versatile, if pricey.
