The triple-layer insulation keeps your beverage ice-cold all day long. Meanwhile, the FreeSip spout lets you drink however you like, with built-in straw and a wide mouth for big sips. And thanks to the easy-to-use flip-top lid, there's no struggling with screw-tops, and the lock keeps it closed and clean no matter where you are. Not sold? Well, it's also fully leakproof so you won't lose any precious water tossing it around. And if that's not enough, well, we don't know what is! Check out the smaller Owala FreeSip 24oz Bottle if you need even more hydration.
