The ALPINA MAROI’S clear lines and clean design result in a modern, distinctive shape. The shell of the helmet consists of two polycarbonate plates that fit together seamlessly thanks to Seamless Connection. Edge Protect protects the helmet completely, with soft surface transitions that add a touch of refinement the surface. The exterior is also defined by discreet air vents which are integrated at strategically important points. This ensures optimal ventilation in the goggles while keeping the air channels supplied with plenty of air. Inside, an all-new channelling system directs the air flow around the entire head. This provides cooling air while simultaneously conducting heat away. Not new, but more than reliable for it is the fit. It is identical to the top-selling Alpina helmet. The GRAP served as the model for developing the ALPINA MAROI. The optimised interior fittings with a shaped structure and segmented padding guarantee that it is as comfortable to wear and safe as possible, as the head is fully enclosed by soft material: for maximum protection and maximum fun in the backcountry.
• Air vents at the top of the helmet can be opened and closed using the Airstream Control mechanism. The air flow can thus be regulated and adapted to the weather conditions. This ensures perfect air conditioning inside the helmet at all times.
• All Alpina helmets manufactured using the inmold process are fitted with a robust ceramic shell. A polycarbonate plate is stretched under intense heat onto the shape of the helmet in the making and pressed onto the Hi-EPS body under high pressure and thermally bonded to it. The Ceramic shell is characterized by several qualities: It is impact- and scratch-resistant, UV-stable and antistatic.
• Edge Protect is an additional polycarbonate plate that give inmold helmets a touch of refinement. It covers the edges on the underside of the helmet. This protects the Hi-EPS and increases the helmet's durability.
• Proven a hundred thousand times over and used on all Alpina helmets: the strap buckle with the red push button and multi-step automatic locking mechanism. Ergomatic can be operated with one hand - you can loosen the strap on the way up the mountain and tighten it for downhill - and in a fall the locking mechanism cannot open automatically.
• The inner shell of all Alpina helmets is made of Hi-EPS (High Expanded Polystyrene). The material has microscopically small air chambers that absorb the forces acting on the helmet in the event of an impact. Hi-EPS provides optimum protection and at the same time allows for extra-thin helmet wall as well as narrow helmet shapes.
• In the inmould production process, the polycarbonate upper shell is thermally bonded to the Hi-EPS inner shell of the helmet body under intense heat and pressure. This creates a large and inseparable connection between the upper and lower shell. Advantage: The helmet is very light and at the same time extremely stable.
• The Run System enables all Alpina helmets to adjust to a custom size by using an easy-to-move dial. Alpina relies on the tried-and-tested Run System Classic for its ski helmets, a flexible head adjustment system with a central dial. A twist mechanism allows the headband to be adjusted more loosely or more tightly. The large dial is equipped with a non-slip two-component mix and can be operated perfectly with ski gloves.
• A helmet can only provide the best possible protection if it remains in the optimum position in the event of an impact. The adjustment and fixing of the two straps under the ear plays a decisive role. The Y-clip system ensures a millimetre-accurate adjustment - in a matter of seconds.
