When Thinksport introduced the Thinksport bottle over 10 years ago, most reusable bottles were made of polycarbonate material, which leaches Bisphenol-A (BPA). More recently, it has been shown that aluminum bottles with epoxy liners also leach this harmful chemical. So they first and foremost set out to find a safe material that adhered to our strict chemical policy. All Thinksport bottles are made of 18/8 medical- grade stainless steel. They then went on to design our bottles to be highly functional and great-looking too! Features:
- Double-walled and vacuum-sealed stainless steel - keeps contents hot or cold for hours.
- Features a large opening for cleaning and full sized fruits or ice cubes as well as a secondary drinking spout.
- Perfect of hot or cold beverages - does not sweat (for cold contents) or burn your hand (for hot contents).
While we recommend hand washing our bottles, they are dishwasher safe as long as you remove the cap and strap first. When not using our bottle, keep it clean and dry.
