The Insider has a very comfortable, semi-streamlined shape with excellent peripheral
vision and will accommodate glasses or goggles. Ours have a cleanly installed
radio headset and finger switch if you so desire. The Insider helmet is tested and certified to CEN
Standard EN 966, which is a European testing standard specifically designed for
helmets used for sport aviation. This standard includes tests for shock absorption,
penetration resistance, and specifications for visibility and head mobility.
