This is what she's ending up with...
They don't look like much here, but I promise you these are formidable pants. I made them from a bottom-weight fabric, the crotch seam is flat-felled, and the side-seams are "french". Amusingly, when I folded the top of the pants over to create the waistline (as I usually do), each seam had become too bulky to machine-sew through. So, I hand-stitched those sections shut, breaking a hand-needle in the process.
An example of one of the cargo pockets. They have a drawstring at the top of them in order to keep any goodies inside safe, and each is large enough to hold two... er... adult beverages.
The back pocket is a single-welt pocket and is deep enough that she can fit one hand in her pocket.
