The LifeStraw Go Series is the ultimate companion for safe, great-tasting water for travel and everyday use. The BPA-free bottle filters out harmful substances, allowing you to refill water at airport restrooms, from a tap in Mexico, or at a gas station during a road trip. The advanced 2-stage filter enhances taste and protects against bacteria, parasites, microplastics, chlorine, mud, sand, and cloudiness. The BPA-free bottle is made from 50% recycled plastic. All components of the LifeStraw Go Series water bottles have been fully tested to be BPA-free. Do good on the go and avoid single-use plastic bottles.

LifeStraw is proud to be a certified B Corp and climate-neutral brand committed to meeting the highest standards for verified social and environmental performance, transparency, and accountability.
