This is one of the most bomber water bottles we have ever tested. At 40 oz., this will last you all day and keep your ice water cold during long summer hikes or even sitting in your car. The straw lid is convenient for a bottle this size and makes drinking easier – although our testers did experience a little leakage when the bottle was rolling around the car floorboards. If you are a little more reckless with your gear, we recommend going with the flex cap (link this version https://www.hydroflask.com/40-oz-wide-bottle#92=60) as it is solid and can handle a bit more abuse.
