The Nathan 1.6 L Insulated Vapor Bladder keeps your fluids colder for longer while its unique hourglass shape drastically reduces sloshing. The bladder's top opening lets you quickly fill and clean it when the time comes. A soft bite valve prevents leaking and is easy on your teeth, and the kink-resistant tube can be cut to the desired length.
