Editor's Pick: The 40 oz (1,183 ml) capacity is generous—whether you're heading to the gym or running errands, one fill lasts most of the day. The double-wall vacuum stainless steel construction keeps morning iced water cold until evening, and it holds hot drinks for hours too. It comes with both a direct-drink lid and a straw lid—switch to the straw lid for one-handed sipping while driving, or use the direct-drink lid to gulp water after a workout. The lids are dishwasher safe, so no need to scrub by hand.
