Nalgene's 32oz wide mouth water bottles are made in the USA, and built to last through years of afternoon hikes, sunset rides, and hard-charging powder days. Leakproof, lightweight and BPA/BPS free. Printed with the St. Lawrence University down the side. 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.
