Hi,
I bought a set of GIVI soft panniers and am very happy with them. I have used them on 4 separate trips with no issues. Capacity = 25 lt per bag and they are fully water proof, tested in monsoon conditions in Scotland last year. I bought some heat shield material off E Bay and stuck it to the back of one of the bags. I also bought a set of Shad brackets just to keep the bags off of the exhaust and the bike.
