I just got the Cortech tri Tankbag and boy is it huge. If you have all the bags connected, you wont have to worry about the wind

. It absolutely dwarf's the small tank bag, but surprisingly the magnet's aren't near the strength or quality that Fieldsheer has.
I really like the little Fieldsheer bag but it will barely hold the frog tog rain suit and doesn't leave any room for anything else.
The quality and craftsmanship is excellent and would be great on a larger motorcycle, unless you are making a long trip and wished to take the kitchen sink with you
