What can I say. I'm in touch with my feminine side Although that example from Ducbird (thanks Ducbird) doesn't match my leathers.
Halfords used to do a folding rucksack in their motorbike section. Don't know if they still do. I had one and it was very useful; so useful in fact that some thieving froggy bastard decided he wanted it more
I used a Knox six pack rucksack for 2 yrs, cost £36 iirc, fab construction. Material was waterproof and very heavy duty, good practical design in and out, only the up-and-round zip design finally began to show wear(sometimes cross meshing and causing the zip teeth not to mesh correctly) so I stopped using it but would happily recommend Knox as a brand. Good choice!
Here's my vote.....North face shoulder bag.... Pretty knackered (had it for about 5 years now) - cost about 60 quid. Totally waterproof. Take it everywhere with me - the straps extend so you can get a load of stuff in there, holds my 17" laptop that I use for work....big dell workstation that's pretty thick, plus other stuff as well. its got a waist strap so you can stop it moving around - knee has touched down on the mountain section at the TT while carrying food, DSLR and spare lenses, phone, and drinks for 2 of us....so if you pull the waist stap tight it doesn't move around....
