To promote the theatrical premeire of X-MEN: APOCALYPSE, 20th Century Fox Films and Hanes got together for a partnership focused on the "X-Temp" line of temperature-controlled undergarments. X-Temp shoppers received a free X-Men-themed bonus t-shirt in specially-marked packages of Hanes X-Temp shirts. To coincide with the giveaway, Hanes and Fox also teamed up to give away 5 authentic, wearable Magneto helmet replicas. By entering the sweepstakes on the Hanes website, fans got the chance to take home up to $500 of X-Men memorabilia.

The program was promoted on the Hanes website, on their various social media channels, as well as with a TV Spot entitled, 'X-Men: No Pants.'
