A conceptual design to hydrate the user, when taking part in water sports like Surfing or Body Boarding. This vessel carries around 300mL of liquid allowing just enough consumption for the user to stay hydrated and energized when performing physical activities in the water. 

 

Designed to fit nice and snug into a mens size wetsuit, the vessel becomes almost invisiable to any on looker apart from the small drinking tube. 

It's still easy to perform activities like surfing as the vessel is slim lined and only about 20mm thick.

In additon the vessel possesses a slight curve to fit with the users chest.
