It shares the same look as the Catalyst with the flip over cover and pull tight inside compartment. This bag is slightly larger than the Catalyst giving it more room for that morning jacket and lunch for work. There is no top flap zipper bag, but it has two side or "end pockets help hold sodas or other things.
Like with the Catalyst, I generally can use it on all my bikes, mounting to a variety of handlebars, flat bars, bullhorn bars, upper or even lower on bmx handlebars, and it still doesn't seem too big.
