Pura’s Sport 18oz stainless steel bottle is ideal for school, work, at the gym or outings. It is lightweight and made from safe, high grade, anti-bacterial, #304 stainless steel, and unlike other stainless steel bottles that use plastic tops, Pura’s Big Mouth® Sport top is made from 100% medical grade silicone, so you can be sure that you are truly using a 100% NonToxic Certified drinks bottle (BPA/BPS-free). The silicone sleeve makes handling the bottle so much easier and it doesn’t even needed to be taken off to wash it up.
The bottle has a large opening for easy pouring and filling and is dishwasher safe. The bottles can be used with any of the  silicone lids including the sippy cup, straw bottle or infant bottle by simply changing the lid.
