The Contigo AUTOSEAL Kangaroo is great for when you’re planning on working up a voracious thirst. The bottle holds 24 ounces of liquid. It’s not super lightweight, so I wouldn’t go jogging with it, but I will take this to spinning class or any other gym class when you sweat like a MoFo. You’ll love that this bottle has a space to put your I.D,. gym card and keys, so you don’t need to take a purse to the gym. If you want to take it in the great outdoors, say a hike, the bottle has a carabiner clip so it can be attached to a backpack. It’s also dirt resistant and BPA-free. Just press the “push” button to take a swig from the bottle and when you let go of it, the opening to drink will close. This ensures no spillage of the water. The transparent bottle has markings on the side to help to measure how much water you’ve had and how much is left. The Contigo is BPA-free and retails for $12.99.
