Platypus couldn’t make filtering water with the GravityWorks Water Filtration System 2.0 Liter any easier. The GravityWorks 2.0L system holds 2 Liters (4 Liters depending on the configuration), is light weight and packs small, making it ideal for 1-4 people in the backcountry. Two kits and a range of accessories allow both filtering and backflushing with whatever you like to drink from. They work great for base camp or for over-nights. Keep yourself hydrated and always have water wherever the mountains take you with this awesome and easy filtration system.
