Choosing a water bottle is like buying bar soap: you can penny-pinch and get a three-pack of Dial for two bones, or you can upgrade to Dr. Bronner’s and enjoy the marginal benefit of bathing in citrus oils every morning like a refined gentleman. Your old Nalgene Silo? Dial. Fortunately, the options for an upgrade are abundant, ranging from straightforward bottles for the gym to handheld bottles for marathon runners to double-walled glass vessels that could double as flower vases. These are ten of our favorite water bottles for every activity.
