Dierks Bentley recently made his annual Polar Plunge, but he was a few days late, 13 to be exact, so he decided to “punish” himself by staying in the cold water for 13 minutes, and he added one additional minute for the heck of it. At Percy Priest Lake outside of Nashville, Dierks was dressed in just a pair of shorts and a ballcap when he walked into the 36-degree water. Check out the video of his 15th plunge below.

Dierks just released the video for his latest song, “Black,” and he’s about to hit the road for his What the Hell Tour, featuring Jon Pardi and Cole Swindell. The trek kicks off in Dayton, Ohio on Thursday (January 19th).
