Why use one hand to hold a drink when you need both hands to snap, text, or post? The HydroBeltbag can be worn crossbody or around your waist--but wait, it has a patent pending "HydroHolster"--a removable pouch that has a drink holder hidden away inside it. Wear it when you want it, take it off when you don't.
The Beltbag itself is water resistant and has pockets in the interior with room for phone, keys, wallet, essentials with a zippered pocket in the back.
Measurements: Beltbag 5 x 7 x 2 inches, HydroHolster: 3.25x3.25 inches (pouch), 7 inches tall, 3 inch diameter (drink holder)
