Our eco-progressive mission leads us to constantly seek opportunities to increase the usefulness and life span of our products. Our new Universal Lid functions on ALL Pura bottles. It provides a totally water tight lid to any of of our bottles. If you want to put hot water or a hot beverage in any of our insulated bottles the Universal Lid is the best choice. Use with our 5oz or 11oz to securely store breast milk, baby food, or any number of snacks as it is the perfect size for lunch boxes! If your kids aren’t babies anymore then have your Coconut Latte or Green Tea poured straight into the 9 oz or 16 oz insulated bottle and add the Universal Lid for water tight transport of hot beverages on your way to the office. With the Universal lid you have the ability to use any Pura bottle to carry any beverage on camping trips, to the beach, or on-board a sailboat. Unbreakable stainless steel and plastic-free construction is not just for kids!
