The NEW Sawyer Squeeze Filter is the lightest and most versatile filtration system on the market. With a total field weight of 3 ounces and ability to roll up, it takes up virtually no space in your pack. This product includes one 1L pouch that can be reused hundreds of times. A larger 2 liter capacity bag is also available. 

Simply fill up the pouch of your choice at a lake, stream or river, screw the filter directly onto the pouch and : 
1) Squeeze the bag and filter water into your water bottle or container of choice. 
2) Drink directly from the filter which has a built in push pull cap for on/off functions. 
3) Attach the filter onto most threaded water bottles including 2 liter bottles. 

The Squeeze filter is perfect for traveling abroad where tap and bottle water cannot be trusted.
