Increasing the functionality of your Platypus GravityWorks filter (sold separately), the Platypus Universal Bottle Adapter allows the system to be connected directly to a wide array of water containers, including MSR Dromedary bags, Platypus bottles, narrow or wide-mouthed Nalgene bottles, most metal water bottles and even standard soda bottles (all bags and bottles sold separately)! The Universal Bottle Adapter also includes a closure cap that keeps the adapter free of debris while in your pack.
