The Owala FreeSip Sway is a 30oz vacuum-insulated stainless-steel tumbler featuring Owala's signature 2-in-1 FreeSip spout — you can sip through a built-in straw upright or tilt back and swig. Triple-layer insulation keeps drinks cold for up to 24 hours. The tumbler has a push-button, leak-proof lid that locks, an ergonomic bucket handle, and a cupholder-friendly base. Made from BPA-free 18/8 stainless steel; the lid is dishwasher-safe and hand-wash recommended for the bottle. At 30oz, it strikes a balance between portability and all-day hydration. Best for daily commuters, school, sports, and travel who want flexibility in how they drink without sacrificing leak-proof reliability.
