LifeStraw® Go incorporates award-winning LifeStraw® technology into a refillable water bottle so you can carry safe drinking water with you on the go. Simply scoop water from a river or pond, screw the lid on, and sip safe water through the mouthpiece. The water bottle design is ideal for hiking, backpacking, running, and other activities where you’re on the move and aren't always near a water source. LifeStraw® Go uses advanced hollow fiber technology. This highly efficient method of filtration requires no chemicals. The LifeStraw® Go water bottle is designed to be filled up and taken with you on the go. Stop at a river, stream, or even a puddle, fill up the bottle, screw on the lid and filter, and sip filtered water through the mouthpiece. After each drinking session, unscrew lid and blow through the LifeStraw® to expel dirty water.
