downhillkypärät

Downhillkypärät, also known as full-face helmets, are a crucial piece of safety equipment for downhill mountain biking and other extreme cycling disciplines. Their primary function is to offer maximum protection to the rider's head, face, and jaw during high-speed descents and potential impacts. Unlike open-face helmets, downhill helmets enclose the entire head and feature a chin bar to safeguard the face.

These helmets are typically constructed with a hard outer shell, often made of polycarbonate or composite materials, designed to absorb and distribute impact forces. Beneath the shell lies an inner liner, usually made of expanded polystyrene (EPS) foam, which crushes upon impact to further dissipate energy. Many downhill helmets also incorporate advanced safety features such as MIPS (Multi-directional Impact Protection System) technology, which helps to reduce rotational forces on the brain during angled impacts.

Ventilation is an important consideration for downhillkypärät, as riders can experience intense physical exertion. Helmets are designed with strategically placed vents to allow airflow and keep the rider cool, though the emphasis remains on protection. Adjustability and comfort are also key, with features like adjustable retention systems and padded interiors ensuring a secure and comfortable fit. The weight of these helmets is generally higher than lighter-duty helmets due to the increased protective coverage.
