The Speed Demon isn't loaded with high technology, but it offers good bang for your buck. It's not too high or too wide, so it presents a small profile to the wind. This is thanks to thin ear flaps, which don't offer much crash protection, but do sit very snugly to the side of your head to reduce drag.
It kept our heads cool as there are only five main contact points between your head and the inside of the helmet. There are six vents at the front too, which aid airflow but increase drag. It offered lots of adjustability to help you find the best position.
