No need to fiddle with pumps, filters or chemicals, the Widepac with inline Sawyer filter lets you refill your water anywhere. The Sawyer mini-filter works when water passes through the side walls and through the filter micro-fibrous tubes, trapping protozoa and harmful bacteria giving you clean drinking water with every sip.
The filter lasts for up to 37,000 litres from freshwater lakes, rivers or streams. The Sawyer filters are easy to clean, just backwash and use over and over again. No replacement cartridges needed.
