Jennifer Garner has long been the queen of effortlessly practical style, whether she's running errands, cooking in her kitchen or powering through long filming days. The actress was recently spotted on the set of One Attempt Remaining in Studio City, and while we loved seeing her back in action, it was the everyday essential she carried between takes that caught our eye: her trusty Stanley water bottle. Unlike the brand's ultra-viral tumblers, Garner's pick features a clever top-handle design that makes it especially easy to grab and go (and perfect for busy days on set).
