Ronnie Lott knows a thing or two about toughness. A 10-time Pro Bowler and winner of four Super Bowls, Lott is a Hall of Fame player that obliterated the opposition for 14 NFL seasons.

So when Lott talks about toughness, people listen.

Lott is working with Hanes to promote their new line of ComfortBlend clothing, which feature the brand’s softest t-shirt ever. Hanes partnered up with Harris Interactive on a new survey that identified the top 10 toughest fan bases for NFL teams. Fans who tweet about their city’s NFL toughness or nominate a tough fan using the hashtag #AmericasToughest, can score free COmfortBlend t-shirts for their trouble.
