And it’s all for charity.
It might be cold outside, but that hasn’t stopped these guys, and girls, from running through the streets in Santa inspired underwear.
It’s Christmas and that means its time for the Santa Speedo Run.
Held in cities across the US, the event raises money for several children’s charities.
The Santa Speed Run started back in Boston in 2009 and has been held in cities such as Detroit, Atlanta, Annapolis and more.
While the run isn’t necessarily a gay event, we do love watching men run around in skimpy underwear!
Take a look at some of the snaps taken during the event below:
