Rock band Yoon Do Hyun Band showed their fun side in a recent photo shoot for camping equipment.

The members of YB are all men over 40, but they don't seem so old in their photos.

YB's jump in front of the RV shows the essence of YB, which is "freedom".

Campline, the sponsors for the photo shoot, expressed their satisfaction, saying, "YB showed great synergy with our campaign of 'enjoying Rock music outdoors'. They captured the essence of 'active' and 'fun' very well."
