H&M has announced a partnership with the US-based Mentor Foundation to launch a collection of t-shirts to promote the prevention of drug abuse.

The one-off collection is currently on sale in 45 H&M stores in the US, with 25% of sales being donated to the Mentor Foundation.

The collection includes three T-shirts for men and two tank tops for women - ranging from $12.95 to $17.95.

"We're proud to partner with the Mentor Foundation for this campaign. Together we can raise protective awareness for young people. The purpose is to provide H&M customers with stylish clothing, while at the same time raising money for a great cause," said Daniel Kulle, H&M North America president.
