The Evo 21 offers a true 360-degree concept with a brake warning light, turn signals, as well as front and rear lights. With 30% more ventilation and a weight of 350 g, you stay one step ahead of the competition, keep a cool head, and glide through the wind with minimal air resistance. In the event of a fall, it sends an SMS alert with your exact GPS location to your emergency contacts. The light is visible from all angles and, due to its high position on the head, is also easily recognizable from long distances. The helmet features patented crash detection and SOS technology from Livall.
