The 32oz Wide Mouth Sustain Water Bottle by Nalgene is a drinking bottle that is made in an environmentally friendly way. 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. But not only that, the material also contains no harmful plasticizers such as Bisphenol A (BPA) or Bisphenol-S (BPS). The Tritan Renew material is also super light, shatterproof and dishwasher-safe. The drinking bottle has been designed with a wide mouthpiece so that ice cubes or fruit can easily fit into the bottle. The continuous semi-buttress thread keeps the bottle tightly closed - ideal for on the go, so nothing can leak.
