Nalgene Sustain 32 oz wide mouth water bottles are constructed from a durable, BPA-free tritan co-polyester material; suitable for hot and cold liquids. Stain and odor-resistant, it features a convenient loop-top design.

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.
