The 16oz Wide Mouth Sustain Water Bottle from Nalgene is an environmentally friendly and innovative drinking bottle. The Sustain product line bottle is made from a material derived from 50 percent plastic waste (using ISCC-certified mass balance), further offsetting the use of fossil fuels and reducing greenhouse gas emissions. It also eliminates the use of harmful plasticizers such as Bisphenol A (BPA) and Bisphenol-S (BPS). The Tritan Renew material is super light, shatterproof and dishwasher-safe. Thanks to the wide mouthpiece, ice cubes or fruit fit easily into the bottle. The drinking bottle is also leak-proof - the continuous semi-buttress thread keeps the bottle tightly closed.
