The path to reliably clean drinking water begins with Eddy®+ filtered by LifeStraw®. Whether you are a couple days into a backcountry trip or looking for an everyday water bottle, you need a trustworthy source for safe water wherever you roam. Water passes through two separate stages of filtration - the Hollow Fiber Filter removes bacteria, parasites, and microplastics and the Ion Exchange Filter reduces lead, bad taste, chlorine and other unwanted chemicals. Leak-proof when closed and spill-proof when open, the universal Eddy + straw cap and bite-valve interface delivers a high flow for steady hydration when you need it most. The main vessel is constructed in durable 18/8 stainless steel with a sweat-proof powder coat finish and keeps water cold for hours with double wall vacuum insulation. BPA, BPS, and BPF free.
