Are the so-called winter cycling helmets being touted by manufacturers truly providing the necessary safety features for riding in harsh, cold conditions, or are they just a cash-grab, slapping a winter label on a standard helmet with some token insulation, and what specific features should we be demanding from manufacturers to ensure our safety on the roads during the coldest months of the year - MIPS, adjustable ventilation, or perhaps something more innovative, like integrated heating or advanced moisture-wicking technologies, and can we trust the current crop of winter helmets to protect us from the unique hazards of winter riding, such as black ice and reduced visibility.
