Fanny packs have never been cool, but perhaps you'd give one a second look if it was waterproof. Aimed at those seeking aquatic recreation, the RunOff Waterproof Waist Pack is submersible and, in case you drop it in the drink, buoyant. The real draw for the forever-connected will be its clear window and smartphone pouch, which allows you to work the touchscreen while your phone's safely locked inside. The TPU bag features a toothless zipper that manufacturer Nite-Ize says is completely waterproof and dust-proof. It'll hold 3 liters' worth of stuff. The adjustable straps allow it to be worn like a cross-body sling, or like a fanny pack for those who don't give a damn.These run $80.
