FreeSip UK

I'm kind of a big deal. Why? Because I invented the whole sip-or-swig thing. Hold me upright and sip through my built-in straw, or tilt me back to swig through the wide-mouth opening. But that's not all—one push and I pop open, one push and I'm locked tight (bye bye, leaks). Basically, I'm the overachiever of water bottles, and darn proud of it.
