Fishing vests are unisex.

Now that I think about it neither my wife nor I own one - a christmas opportunity lost

Tactikool pants also have big pockets, even the women’s version.*

Find them wherever cops get there uniforms at. (Galls comes to mind.)

*Not necessarily fashionable.

I’m lucky enough to have overalls supplied and washed by my work. Pockets for days - I’ll have to do an EDC post one day.
