I have found it also makes a great place to stow a cell, folder knife, and cliff bars on mountain bike rides and hikes. Just remember to take the stuff out before going back in the water. I'm going to make sheep wool accessory pads for my trout flies to use during the off season.
When I'm diving 105 miles offshore at Cortez and Tanner Bank I plan on stowing my survival mirror,green dye, and strobe in two of the unused pockets. I have this gear on my life guard float, but one time a big yellow swam up current with it and I realized I would've been screwed if the live boat didn't spot me in the big seas. Just another use for a great product.
Cheers, Don
