Inside: fits a small wallet, smart phone, and pens on the inside with room left for my keys to fit.

Outside: tight fitting net pocket can hold a small folding knife and a few keys. That's about it.

Patch/velcro: The flag patch is small enough that it doesn't get in the way and the velcro holds well.

Zipper: good thickness, doesn't come un-done, no accidental openings.

Color: the tan is a darker shade and is nice.
