• Duo is a new patent pending closure cap for non carbonated beverages that allows you to share your (or someone else's) drink in a totally hygienic and non-embarrassing manner
• Thanks to embedded one-way valves, saliva can not return into the bottle - keeping the water fresh even when bottle has been left for periods un-finished
• Its fun, its "cool", its safer for children, it prevents spillage, and its smoother to drink with, with less suction, and with no backwash!
• It wistles! After consuming the water and removing the Duo closure cap, it acts as a "whistle" while blowing through any of its mouthpieces, generating different "tunes" as the mouthpece is extracted to different lengths.
• It's good to have Duo when you are together with a friend or family member, and you wish to share your drink (at school, or college, in the car, stadium, concert, etc…)
• Many of Duo's features provide a strong advantage while marketing it for the Children and Boomers segments. For more details see The water bottler's benefits
