I used to just put my stuff into the little pockets in my bag, but have since switched to sort of a pouch which was designed for a phone, but fits everything I need. But where do you put your stuff if you don’t have a bag to put the pouch in? I envy woman for being able to walk around with a bag the size of a phone without looking stupid. Do you always carry a backpack? Or do you put your stuff somewhere else?
I wear cargo pants which have lots of space for smaller stuff, since I generally prefer a loose fit. For my weekly groceries I have a big ~40L messenger backpack from Ortlieb, since they only have one big compartment, with a regular cotton bag inside if I need it.
