The path to reliably clean drinking water begins with CamelBaks 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 made with Tritan Renew, a highly durable and lightweight plastic made with 50% recycled material. A more sustainable solution, Tritan Renew is made using a recycling process thats more efficient than standard mechanical recycling, producing a superior material with less demand on finite resources. It’s odor and stain resistant and free of BPA, BPS, and BPF. Two Stages of Filtration: Stage 1: Hollow Fiber Membrane Removes 99.999999% of bacteria (E.
