The Owala FreeSip is tough, never leaks (when closed) and offers two drinking methods — a straw and a larger opening for guzzling that conforms to the shape of the user’s mouth. Easily unlock the Owala FreeSip with a quick button press and secure a leak-proof experience by pushing it back down to seal it shut. The FreeSip bottle fits comfortably in our  so you can get them as a duo for your travels.
