No intention of hijacking this post, but men’s pockets leave a lot to be desired too.

Jacket pockets are ludicrously small even on brands like Carhartt.

Pants pockets barely hold modern cell phones.

Right handedness is assumed.

And for both men and women, why isn’t there a cell phone pocket mid-thigh adjacent to the outseam?

Everyone carries one, and wrestling one out of a front pocket while sitting is an act of contortionism while carrying it in a hip pocket is an invitation to damage, loss or theft.

I'm a guy and I had to start carrying a ~~purse~~ men's carry-all / courier bag (which I call a purse).  

Between the hand cleaner, extra mask, sunglasses, umbrella, snacks, battery pack, tiny folding shopping bag, etc, it just got to be easier to have something I can sling over my shoulder and not have to worry about putting something down and leaving it behind.

Now I can also carry around other stuff.  I bought but haven't yet worn outside, a drop-bag.  It's a different level of dork that I haven't quite got the courage to wear outside.
