What material is used to make the bottles?Updated 5 months ago

We use a food-grade 18-8 steel to make our Insulated Stainless Steel. This grade of steel is non-magnetic and extremely resistant to corrosion and is FDA certified lead free.

The Glass Borosilicate Bottles are made of a specific type of glass called borosilicate. It is designed for thermal expansion so it will not crack during drastic temperature changes.

The Tritan® Plastic Bottle is made of a material called Tritan®. It is a medical-grade, premium plastic, free of BPA (Bisphenol A), BPS (Bisphenol S), and EA (estrogenic activity).
