When Thinksport first introduced their bottle 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 the Thinksport team set out to find a safe material that adhered to their strict chemical policy. All Thinksport bottles are made of 18/8 medical- grade stainless steel.

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)
