I bought this because I belong to a group of senior hikers.  We take short weekly jaunts that rarely go over four hours total.  This pack can hold a small lunch and snack along with my keys, chapstick, sunscreen, and a cigarette pack sized first aid kit. The belt is strong enough that I can slide two mesh water bottle holders on it.

I've used it as a hands free purse several tims. I love this thing.
