Tank Top Style Showdown: Penn Badgley vs. Zac Efron (POLL)

Beefy Biceps!
Some of Hollywood's best.
Summer time is hot, hot, hot which means that guys are doing what they can to stay cool. One popular way for guys to beat the heat? Tank tops!

Gossip Girl star Penn Badgley (who is in humid NYC) and Zac Efron (who is in the sticky South) were both seen on set of their latest projects (respectively) on Wednesday and were both rocking tanks!

We think both were looking great and thank them for giving us front row seats to the gun show, but we have to ask — who is working the tank best?

Do you prefer Penn’s striped sleeveless number? Or do you like the simplicity of Zac’s wife-beater?

Let you voice be heard, and cast your vote in the poll!
