Now kids have the chance to have their own version of our best-selling vacuum insulated Boulder water bottle. So fill it up with water, juice, chocolate milk, a smoothie and toss into a backpack or lunchbox with no worry about wet artwork or soggy cookies - the leak proof top keeps drinks inside where they belong. And not just for kids - a lot of grown-ups love the convenience of the compact size too and now available with interchangeable tops!
