Introducing the Dark Skwal. The main difference between the Shark Skwal and new Shark D-Skwal, is that the D-Skwal does not have LED lights. The Shark D-Skwal is a quality helmet, less expensive than the Skwal without the LED lights and connections,and is wearable, urban and sporty looking. Main features of the Shark D-Skwal are the dropdown internal visor and pinlock included as standard.The D-Skwal is developed from the inside out, to give a more comfortable fit and shape. Designing helmets this way is the latest safety development where Shark engineers develop the protective inner EPS (Expanded Polystyrene) around a model headform, matching the correct amount and density of EPS to where it is needed the most. The outside shell is then designed around the EPS, which is the opposite way helmets were traditionally designed.
