Square is the product of a 3 year collaboration between engineers and designers with backgrounds from Apple, Frog Design, and Stanford. Square bottles stand in contrast to older (and dare we say, less evolved, models) because of their thoughtful composition. These vibrant styles unscrew from both ends, are dishwasher safe, won't roll away if dropped, and are guaranteed for life by the makers at Square. Recently featured on the cover of Wired Magazine, these water bottles have gone world famous. Celebrate Fitness Week with a whole new way to get refreshed post-workout.
