Stephen Amell and Jared Padalecki are shirtless in the following photograph.
But they didn't strip partially down on Facebook merely to make female followers everywhere drool and ogle.
While vacationing in Lake Austin, Texas over the weekend, the close friends and fellow CW stars decided to pose on a dock in half their birthday suits in order to bring attention to an important cause.
No, not their abdominal muscles.
"Stay Sunday Strong," Amell wrote online along with a link to his Padalecki's charity T-shirt campaign. "My buddy Jared Padalecki wants you to Always Keep Fighting."
Padalecki has been very open and honest about his struggle with anxiety and depression for years now.
In response to this illness, the Supernatural stud created T-shirts to help benefit To Write Love on Her Arms, an organization that supports people struggling with similar mental health issues.
"To a degree there is certainly a taboo attached to it still," Padalecki has told E! News. "There's still a large portion of the population who just want to say, ‘Buck up. Put on a happy face and everything goes away.' For some people, that works."
But for others?
"For those of us who aren't so blessed, the message ‘Always Keep Fighting' is for us," he says. "Generation by generation, we're slowly stripping away that taboo, that strange dynamic of, ‘Oh, there must be a problem with you if you feel this way."
Amell, meanwhile, will return to your small screen when Arrow Season 4 kicks off this October; while Padalecki will do the same when Supernatural Season 11 premieres the same month.
