The classic BPA/BPS-free Nalgene Narrow Mouth bottle in 3 wild expression prints. Whether you’re exploring a new trail or visiting one of your favorite camping spots, our new Wild Expressions series, designed by Colorado artist Jimmy Bryant, is the perfect companion for showcasing your wild side. All Nalgene bottles are now made with a revolutionary resin powered by new recycling technology that transforms plastic destined for landfills into high-performance BPA/BPS-free bottles. Made from material derived from 50% plastic waste (using ISCC certified mass balance), further offsetting the use of fossil fuels and lowering greenhouse gas emissions.
