French fashion photographer Fred Goudon released a 2016 charity calendar featuring French firefighters.

The men of fire service pose almost naked in their department showing off their well-fit body.

The money raised will be given to the NGO charity Pompiers Sans Frontières, a French organization that provides humanitarian aid.

“For me and for many others, firefighters are heroes. Every single day, these guys are out there saving people’s lives,” Goudon told The Local. “And they’re all so nice, so strong… and you can see it in the pictures that there is a kind of pride in them that others don’t have.”
