Sustainability in your hands. Nalgene is proud to be the first to market with a new resin powered by next-generation recycling technology that transforms plastic destined for landfills into high-performance BPA/BPS-free bottles. The new Nalgene Widemouth Sustain 1L Water Bottle is made from 50% certified recycled content further offsetting the use of fossil fuels and lowering greenhouse gas emissions. The equivalent of 8 single-use bottles was recycled in the production of one Nalgene Sustain Bottle. The attached loop-top never gets lost and screws on and off easily. Printed graduations let you keep track of your hydration; graduated to 30oz / 900ml, but the brim capacity gets over 32oz / 1L. Super durable, leakproof bottle that is guaranteed for life.
