So I've been able to use this pack a few times now and its definitely a better pack when wearing my waders over my simms guide waist pack which has been dunked several times. wearing the umpqua pack high on my chest puts everything out of harms way and is actually very comfortable. Now that being said, I did have to collapse some of my fly boxes into 1 so I could have room in the large storage compartment for other things. But other than that I love it.

Im not sure if I will use it or not when wet wading or not, but its definitely a great pack.
