Incredibly light and designed to keep your head cool, the Kask Vertigo 2.0 Helmet boasts a precise fit and super compact shape. The Vertigo has a unique hinged adjustment system that allows for both size and up/down adjustment, which together comfortably cradle the nape of the neck. The helmet size can be adjusted using either the dial or finger push system. This system also includes ventilated, non-stick pads. Working together, these features give the helmet a superior fit and deliver a feeling of improved safety and security. After putting on the helmet and fastening the chin strap, the divider moves to fit comfortably around your ear lobes without you having to do anything. Cooling ventilation is achieved by means of 24 large air vents which do not compromise safety or aerodynamic qualities of the helmet. The internal pads are made from two layers of CoolMax to help draw perspiration away from the head and these pads are removable and washable. The helmet is secured thin nylon fixed straps and quick release buckle. Reflective stickers on the back of the helmet increase visibility in the dark.
