If keeping cool in time trial helmets has been an issue, then the Lazer Tardiz may be the right aero helmet for you. Their innovative Aquavent is a ventilation port on the top surface of the helmet where you can use your bottle to deliver water into the port to reduce overheating, which then is filtered down along perforated EVA padding around the head. Front vents helps keep the rider cool while rear vents allow for heated air to escape. It’s also the first time trial helmet with multiple surface treatments. Smooth front glass meets the least amount of resistance for optimal airflow and their Rollsys fit system provides a comfortable 360 degree fit.
