This is a great boyancy aid, high orange visibility, love the front zip pocket for my snacks.
The water carrier is a great idea but lets it down badly, it hasn't been made to fit in the pocket, it's quite a bit too long. Obviously from some other item, not made to measure in any way.
There is no designated space for the water tube to fit through to the outside nor is there a space to keep it neat at the front.
I love the aid but won't be using the water bladder.
