Took this to Hawaii so I could keep my stuff safe while in the water.  It would only fit either my cell phone or my camera, not both (plus some cash, credit cards, keys, coins, etc). My cell phone is small (smaller than iphone), and normal size point-and-shoot camera.  The strap is very uncomfortable though when u go underwater (for a long time, like snorkeling)... the whole thing spins and squeezes your wrist...and it hurts. Other than that, it kept everything dry the whole time.
