Does anyone have experience with these extra large seat bags? Little has been published about their effectiveness. I like to bring a vest because my rides start in the cool weather near the Golden Gate Bridge in San Francisco. However, most of these rides end up in the much hotter areas of nearby Marin County. On some days, the temperature difference can be as much fifty degrees. When I get hot, I shove my vest into my jersey. Consequently, most of the time, I ride around with a sweaty hump on my back. The Topeak Mondopack Hydro seems to offer an ideal solution for this problem in theory, because it has a handy back pocket for the unworn vest. But practice and theory often differ: I am concerned about possible leg rub issues, fixer problems, and issues regarding its extra length. Also if there is a better solution out there I would like to hear about it.

I find the large gives me ample room for a vest/jersey,tube,gels,keys,tire lever,mutli-tool, & bar/snack. I even a space for other things if I need it.
The small fits everything except the vest/jersey.

I use a Banjo Brothers saddle trunk for long rides that might involve shedding layers and such. Depending on your position, you might get some leg rub, but it has never been an issue for me.
