The salt of the Earth Travel is a totally natural, really effective deodorant that won\'t leave embarrassing white marks on your clothes. It\'s small - so it can fit snugly in your toiletry bag without sparking a fight for space with your toothbrush and face cloth. This little deo will feel right at home in your gym bag and won\'t cause any problems on a flight. The Salt of the Earth Travel Deodorant works by leaving a thin layer of natural mineral salts on your skin. These mineral salts are a natural deodorant and inhibit the formation of body odour on your skin.
