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. This material is derived from 50% waste plastic (using ISCC certified mass balance), further offsetting the use of fossil fuels and lowering greenhouse gas emissions. | Nalgene Wide-Mouth Sustain Water Bottle in Blue | Size 32 oz
