When it comes to hydration, you deserve options. If that isn’t exciting enough, this bottle is ready to spring into action at any time. Just push the button to flip the top open and push back down to lock it shut (and keep out germs). Features you'll love. I have the patented FreeSip spout. Whatever you call it, you’re going to love how my FreeSip straw makes it possible to drink in one of two different ways. Hold me upright to sip through the built-in straw. Or when you’re feeling extra parched tip me up and chug through the wide-mouth opening. Sip or swig. The choice is yours. I have a flip-top lid. The average person unscrews their bottle top 869 times a day. Either way, it gets tedious. With the flip-top lid, you simply press the button and this bottle springs open ready for action. Also, it stays cleaner because you’re not getting all handsy with it every time you open it. I'm leak proof. Some things in life should always be leak proof. Roofs. Water bottles. Life rafts. Definitely life rafts. This bottle is designed to keep liquids inside—where they belong. Carry Loop Hinged loop flips up when you need it; tucks away securely when you don’t. Easy to Clean Designed to be quick and easy to disassemble with minimal hard-to-reach surfaces. 24 Hours Cold Triple-layered, vacuum-insulated stainless steel to keep your drink cold.
