Matt Damon has teamed up with water.org to encourage Santa's elves to purchase limited edition CamelBak water bottles as presents this Christmas.

The Bourne trilogy star features in a campaign film, dressed as Santa, asking children what they want for Christmas. The self-mocking film uses comedy to help spread the serious word of what difference the gifts could make to people around the world.

A $10 donation from every sale of the Groove bottle goes to water.org to help the charity bring safe drinking water to people in developing countries. Available from the water.org shop, the bottles cost between $25 and $35. 

The YouTube film, which can be seen below, has currently received over 28,000 views since its launch on 8 December.
