This is great for when you're rushing down the NYC subway steps to catch your train... and the boys in blue see you don't have a bag so they don't stop you for a spot check.  It has ample space to store your phone (or two), medicine, and just about anything else you would normally store in your jacket pockets.

Two issues:

1.  Not sure if it's waterproof - will have to look it up; and
2.  It can get quite lumpy when you have a few things stored in the pockets and you're on your way out.

I think this product would be better if it were tighter in the pockets - so it would have a snug fit over the shoulder and the waist.
