The Specialty Group, Australia, has developed a luminous textile coating which the company claims will glow in the dark for more than three hours after only 12 minutes exposure to natural light. Called Energlo, the product uses photo-luminescent (light absorbing and emitting) crystals that are dispersed within several layers of the company's waterproof breathable coatings. These coatings are then applied to a range of face fabrics that can be used for wet-weather clothing where additional night-time visibility is required.
