The new Sawyer PointOne squeeze water filter is one of the lightest and most versatile filtration systems available. With a total field weight of only 3-ounces this compact filter rolls up to take minimal space in your pack. Simply fill up the included 1-liter pouch at a lake, stream or river, screw the filter directly onto the pouch and either squeeze the bag and filter water into your water bottle. The push-pull cap built into the water filter lets you conveniently drink directly from the filter to keep things simple. For greater versatility you can attach the filter directly onto a standard threaded water bottle, including most 2-liter bottles. The Squeeze Filter is perfect for traveling abroad where the water source, including tap and bottled water, is compromised or questionable.
