The Nalgene Wide Mouth Sustain Water Bottle is a classic water bottle for the modern, sustainably-conscious world. Now designed with Tritan Renew, this resin is derived from 50% waste plastic, is BPA- and BPS-free, and still crazy-durable. Built for the outdoors, it fits most filtration units, can be stuffed with ice cubes before leaving the house, is leak-proof, and is incredibly lightweight. All that AND made in the USA.
