Lazer Z1 racing bike helmet The Lazer Z1 racing bike helmet is one of the latest additions to the High Performance Lazer helmet range. The Z1 is the lightest helmet Lazer has ever made, but is no less than other helmets in terms of comfort and safety. The helmet is equipped with the ARS Advanced Rollsys Retention System. This allows you to adjust the fit of the helmet in an instant, ensuring that the helmet guarantees comfort at all times. The Adjustable Head Basket also ensures that the height is adjustable. Thanks to the In-Mold system, the helmet is extremely safe. Four different layers form one whole, resulting in optimal strength without extra, unnecessary weight. The helmet also has a notch at the forehead. Thanks to this notch, you do not look at your helmet and your field of vision is optimized. The 31 ventilation holes ensure that you do not overheat even on the hottest summer days. Cooling air flows easily penetrate the helmet while cycling. This top model was worn by professional cyclists during several UCI World Tour victories.
