The firm's first cycling-specific head protector, the Bern Allston Zipmold Helmet is as stylish as it is safe. With input from world leading cyclo-cross racers, it sports 16 vents that provide a whopping 50 per cent increase in airflow over Bern's other models. Forged from high-impact foam surrounded by a polycarbonate shell, it's lightweight, as well as airy, with the low-profile configuration wrapping around - as opposed to on top of - your head.
