Dierks Bentley has teamed up with Flag and Anthem for a clothing line called Desert Son! The line includes T-shirts, raglan shirts, hoodies and trucker hats with original graphics inspired by Dierks. In fact, the eagle with the stars and stripes on it (pictured below) is called the "Riser" design just like the name of his 2014 album and hit song!
If you're looking to pick some up, you can go to the Flag & Anthem site (here) or pick items up in a few select retailers.
