The only bottle you'll ever need! Able to keep beverages hot or cold, our new Willard beverage bottle features a wide-mouth opening and screw top (no straw!), is BPA-free, and a large 16oz. size-- perfect for school days and sports activities. It's double-walled construction makes it easy to fill and clean, while also strong enough to withstand the bumps and bruises our kids put their bottles through!
