How good are Nalgene bottles? Tough as your mama, inexpensive, and lightweight. Why try to recreate something that works when it’s been around the world and back for decades, helping Steve Zissou drink water with ease? All Nalgene bottles are made with a revolutionary resin powered by 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.
