Avril Lavigne's 'Head Above Water' Charitable T-Shirt Benefits Fight Against Lyme Disease

The campaign is part of Lavigne's own organization, The Avril Lavigne Foundation.

Following the release of her powerful comeback single "Head Above Water," Avril Lavigne is continuing to bring awareness to Lyme Disease through The Avril Lavigne Foundation with exclusive, charitable t-shirts.    

"All proceeds from the sale of the #HeadAboveWater charitable t-shirt will help The Avril Lavigne Foundation create an international grant program to directly help individuals affected by Lyme, that would otherwise not be able to afford treatment," Lavigne says. "Please join us in our fight against Lyme disease!"    

Through special programs and grants, The Avril Lavigne Foundation supports people with Lyme Disease and other serious illness and disabilities, providing funding, education and encouragement.  

The shirts are printed on a 100% ring sput cotton unisex shirt, and cost $24.99. They can be purchased on the Foundation's official website, and are only available until Oct. 26.
