It was recently redesigned for better water flow per sip. In fact, the new bite valve allows you to consume 25% more water per sip to stay hydrated throughout the day. We designed this water bottle for convenience and easy care. It’s also compatible with additional CamelBak products and is dishwasher safe, easy to carry, and made from high-quality materials. The Eddy+ water bottle is made from safe materials. The plastic is derived from BPA-, BPS-, and BPF-free materials. CamelBak uses spectrographic testing on all plastics used in our insulated water bottles to verify that BPA is not detected at one part per million or greater. The BPA-free materials ensure that your water is as pure as possible. The insulation keeps it cooler, longer. The universal cap is leak-proof when closed and spill-proof when open. The double-wall vacuum insulation keeps drinks cold and free from condensation. Our Got Your Bak Lifetime Guarantee covers all reservoirs, backpacks, bottles, and accessories from manufacturing defects in materials and workmanship for the lifetime of the product. The CamelBak Eddy+ Insulated Water Bottle is available in multiple colors and with different measurements and weights.
