Obviously, James, you don’t have to deal with women’s clothes 😉 which, if they have pockets at all, tend to be shallower and smaller than men’s pockets. There’s a reason we carry purses for our EDC stuff. Personally, I use a waistpack much of the time for EDC because I can also wear it on a plane and if we have to evac the plane, I still have my waist pack (attached to me) even though we’re not supposed to “bring any bags”.
I also carry a backpack quite often. Not fond of purses except for “dress-up”. Backpacks distribute the weight better so I don’t end up with one shoulder going out of whack.
