Cold kids equal miserable kids – and no matter how much fun your outdoor activity is, as soon as children feel the chill, the fun and smiles disappear. The great news is the solution to staying warm really is simple: layers, layers, layers. By starting with thermals, you’ll give your children a natural radiator of warm air trapped between clothes that will stave off the chill when it’s freezing outside. And if it really is far too cold and miserable to venture outside? They make super-cosy loungewear, too.
