Dads love wearing wellies in the way they love thermostats, spirit levels and bike puncture kits. The wellies are not simply footwear; they’re a declaration of rugged competence, whether cleaning the car or taking the dog out in a downpour. So what better way to treat your welly-loving dad on his birthday or for Father’s Day than by giving him a Wellies Dad 1/2 Pint Mug?
