Men Security Holster Strap Messenger Bags Underarm Shoulder Bag Burglar Phone Pouch Tactical Bag

Good product for the money

As advertised. Large inside (next to ribs) pocket, same width as outside zipper pocket(prox.3x the height). 2pockets on the outside above zipper(one has flap).

As others have already said, the pockets are too small and pretty much unusable for most phones unless you want them falling out. My pixel barely went into one and was sticking out. The zipper section nor the pockets were big enough for one passport, let alone 4. Probably ok if you are only concerned about folding bills. I ended up replacing it at the beginning of the trip with a fannypack. The fannypack Doesn't look as good as this, but doesn't make you sweat profusely either. Three stars at most.

I was looking for a under arm bag that had an additional strap to hold it to my body when bending over

This is not what you want. It has no space. A total disappointment. Actually a waste of time, effort and material. The stitching is good, probably the only good thing about it.
