Owala - 24 oz Bottle

I'm a bit of a star. Why? Because I invented the "sip or gulp" system. Hold me upright and sip through my integrated straw, or tilt me to gulp through the wide opening. But that's not all: a simple press and I open, another and I close tightly (goodbye leaks!). In short, I'm the ultimate water bottle, and I'm proud of it. Keeps cold for 24 hours.
