Sway is the way. Why, you ask. Well, for one, I've got a big ol' bucket handle that makes carrying drinks feel like a luxury, and I slide into cupholders like I was made for them (which I was). Plus, my fancy 2-in-1, sip-or-swig spout makes staying hydrated easier than ever. Stainless steel bottle. Durable, grab-and-go bucket handle. Contoured bottle for a secure and comfortable grip. Patented FreeSip spout with a built-in straw that lets you sip or swig. Triple-layer insulation. Leak-proof lid with push-button to open. Dedicated lock to make sure liquids stay put. BPA, lead, and phthalate-free. Wide opening for cleaning and adding ice. Dishwasher-safe lid and hand-washable cup.
