GravityWorks 2.0L Filter System Bottle Kit

Filtering water couldn't get any easier than with the GravityWorks System from Platypus, so they made it smaller and lighter. The GravityWorks 2.0L bottle kit holds 2 Liters, is light weight and packs small, making it ideal for 1 4 people in the backcountry. Universal Bottle Adapter connects with a wide range of hard bottles, including Platy Bottles and most from MSRR, NalgeneR, Kleen KanteenR, CamelbakR and many more. Use just the center portion of the Universal Bottle Adapter and connect directly to most hydration shutoff valves and tubing without removing them from your pack.
