A special version of the Wasp Air helmet designed to meet the needs of triathlon. Everything about the helmet is shaped around the rider's position and finding the maximum aerodynamic gains. Wasp Air Tri features the Aquavent, a ventilation port on the top surface of the helmet. You can use your bottle to deliver water into the Aquavent to help reduce overheating. Special perforated EVA padding and EVS channels allows the water to filter down and around the head. The water and airflow over the head provides for maximum cooling and riding efficiency. The aerodynamic performance of the Wasp Air is the result of extensive wind tunnels research, scientific insight in aerodynamics and the use of mathematical models that allow Lazer to compute and optimize the shape of the helmet in the virtual environment. The integrated lens is an integral part of the helmet and can be moved forward so that air can flow into the helmet when needed. This creates an airflow through the helmet with air passing over the rider's head and out the two tail vents. A trip wire on the top of the surface of the Wasp creates micro vortices to assure for a smooth airflow over the tail of the helmet. The Lazer advanced Turnfit® retention system makes sure the helmet is snug and comfortable on the head.
