Sunny Boy is just your regular happy Sun. Taking a day off from being the source of all life for a day to relax and enjoy the simple things. He likes to walk his sausage dog, go for a dip, play the banjo, he can even do a kickflip. Join Sunny Boy and enjoy the simple things too in this relaxing shirt.
