Over the weekend thousands of cyclists bared it all as they cruised nude through the streets of Philadelphia.
The annual Philly Naked Bike Ride event was created to promote positive body image, encourage cycling and to become more mindful of fuel consumption.
Riders used body paint to express their own messages during the 10-mile event that began at the Rocky Steps.
