We took the most popular outdoor water filtration device on the market and reinvented it for more versatility, durability, a better grip experience, and an updated design and color. This ultra-lightweight personal water filter straw is made from durable, high-performance materials, has no extra parts to keep track of, and offers an improved flow rate for easy sipping. With 2 ounces and 5 years of drinking water in the palm of your hand, no backpack, pocket, emergency bag, or glove compartment should be without it. Drink directly from lakes, rivers, and streams, or fill a container to use your LifeStraw on the go with protection against bacteria, parasites, microplastics, silt, sand, and cloudiness. Rigorously tested to meet drinking water protocols established by the U.S. Environmental Protection Agency (EPA) and NSF International/ANSI.
