Heidi Klum and Sir Elton John have signed jackets, available online by charity auction, for the 15 Below Project.
The 15 Below Project is literally helping put clothes (jackets) on the backs of some of the 300 000 homeless people in Canada.
3000 jackets will be given out this winter, so homeless people can survive the extreme weather conditions.
Find out more about the 15 Below Project online, or bid on a jacket before December 11 and 15 to help provide funds to grow the organization.
