Granger Smith suffered a huge tragedy last week when his three-year-old son River died in a tragic drowning accident. Now the singer is using his son’s memory to do some good and help others.

Granger’s Yee Yee Apparel site is selling “The River Smith Tribute Shirt,” which features an image of a Yee Yee Excavator with the name “Riv” on its body. The company shares that “Riv’s favorite thing to do was watch excavators scoop up dirt,” adding that they chose the color red because it was River’s favorite.

The post explains that, “100{99cd714f394079a7f0ed2eb1518dd31342ff3ceb5b6c267c3ad8acd5b5a7d66b} of the proceeds from this shirt will go to Dell Children’s Medical Center in honor of River Kelly Smith,” sharing, “He was cared for by the wonderful staff at Dell Childrens before he passed away.”
