Pura’s Sport 11oz stainless steel bottle is ideal for your little one to take to school, on adventures or outings. It is lightweight and made from safe, high grade, anti-bacterial, #304 stainless steel, and unlike other children’s 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 convert into a sippy cup, straw bottle, snack container or infant bottle by simply changing the lid.
