Okay, the Owala FreeSip Sway bottle is kind of a game-changer for staying hydrated.

First off, it holds a massive 40 ounces of water (or your favorite drink), but thanks to its tapered shape, it still fits in most car cup holders and bike cages.

The magic is in the lid.

It has this patented FreeSip spout that gives you two ways to drink: sip through a built-in straw without tilting, or flip the spout open for a big gulping swig.

The lid is push-button, leak-proof, and locks for throwing in a bag.

It's made from triple-layer insulated stainless steel, so it keeps ice water cold for up to 24 hours - no sweat on the outside either.

The big bucket handle makes it super easy to carry around campus, to the gym, or on a hike.

It's BPA-free, dishwasher safe (the lid comes apart), and the wide mouth is perfect for loading up with ice cubes.

The 'Putting Green' color is a nice, fresh minty green.

Honestly, it's one of the most thoughtfully designed bottles out there.
