For the backpack option, I really liked the backpack. It was lightweight, had the compartments I liked and will work great for taking clothes and shoes to the gym! The pouch/fanny pack/rue part of this isn't my favorite. I may not be converting it into the pouch correctly, but it's really bulky. Once you fold the backpack up, 'pack' it into the pouch, and put it around your waist it is pretty stuffed and sticking out. And then you really didn't have any room left in the pack to put what you would want to carry in it.
