ThinkSport - Insulated Sports Bottle - 500 Millitre(s) - NPN: 00000000 -- "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)."Contoured design - makes the bottle easy to hold and visually distinctive from the many, many straight-walled bottlesRemovable mesh filter - keeps ice from blocking the drinking spout and allows users to conveniently brew tea on the go. Unsurpassed testing for material safety - our products undergo rigorous chemical and biologic testing to ensure they do not contain toxic chemicals
