I have a pair of 'Held' cordura (or similar) throwover soft panniers for sale, they're good quality but not waterproof. I've used them for about 10 years and covered many miles with them on the Triumph and later on a Hayabusa. They are secure, 150 mph on the 'busa with no problems. They are a bit grubby but still in good order. I'd like £40 and I'll throw in the matching 2 tier tank bag.
