A couple of native Texans—Kacey Musgraves and Josh Abbott—are raising money for the Hurricane Harvey relief effort by selling personalized t-shirts.

Kacey is selling her red “Texas Rope Tee” for $25, while Josh is selling his gray “My Texas” t-shirt for $30. The proceeds from both shirts will be donated to the Hurricane Harvey relief effort.

Josh has already raised more than $40,000.

Take a look at the tees below.
