The NonFango panniers which are OEM for Ducati are excellent, they have a really good seal and don't leak. I have done several long touring trips ons my ST4S with them and have never had a problem. With the Multistrada you have the option of 2 sizes, the 'sport' panniers or the larger 'touring' units-I would go for the larger ones personally, they are even bigger than the std boxes on the ST range.
