ALPINA Alto Hi-EPS + Visor QV Quattroflex/Varioflex - Ski/Snowboard Helmet with Visor - Black matt/Cobalt-Green Mirror

Style, aesthetic, innovation. The ALPINA ALTO QV  is a visor helmet for skiers who like to look good and be able to see everything. The newly designed and perfectly visor translation rotation Mechanism (TRM) sets new standards in terms of comfort. Thanks to TRM, the visor seals extra tightly to the face, thus helping the helmet to sit compactly and comfortably on the head. The ALPINA high-tech lenses ensure optimal visibility and sharp contrast. The ALPINA ALTO’s active air venting structure guarantees active ventilation. At the same time, the clean play of surfaces in combination with the scattered hole structure of the ventilation creates an iconic look.

DETAILS
Best for : ski - Snowboard - snowsports.
Gender :  Men's  & Women's
Construction : Hard shell helmets - consist of a Hi-EPS core and an impact-resistant outer shell made of ABS or polycarbonate. This combination ensures maximum safety.
Hi-EPS - 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.
Ceramic shell : 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.
Certification :    ASTM F2040 – (EN1077:2007).
UV Protection:    100% UV A - B - C protection.

Protection : UV 400 nm.
Weather : Sunny ,Cloudy, overcast,  snowfall
Transmission    S2 ( 18%-43% ), S3 (8%-18%)
What percentage of visible light passes through the lense, a higher percentage is perfect for low light conditions and a lower percentage is better for sunny days.
Lens :Quattroflex is the term for a specially coloured lens in ruby red, which reduces the proportion of blue in visible light. This increases contrasts in the snow, allowing surroundings to be perceived better and more quickly. Thanks to the lens’s brightening effect, the contours and textures of the piste can be perceived better even in poor weather conditions. A polarisation film of highest optical quality built into the lens completes the Quattroflex effect: Distracting scattered light and glares are filtered out and the contrast is also enhanced. Reflections and mirroring are minimised, which allows icy surfaces and dangerous situations to be seen much better.
Varioflex makes the glass tint automatically. The photochromatic (self-tinting) lens automatically reacts to visible light and darkens in a matter of seconds or brightens if it’s getting darker.
Hicon - Hicon is the name for a certain orange tint of the lens. This colouring has the property of significantly increasing contrasts. This makes the view clearer and better, which increases safety on the way down. The effect is particularly helpful in diffuse lighting conditions such as fog or snowfall.
Doubleflex - Long-lasting fog resistance and lenses do not freeze thanks to double lens in conjunction with fogstop coating
Mirror - Mirror is a lens on which multiple reflective layers are applied. They provide protection from harsh glares and infrared light. Mirror is not only the feature of a highly functional lens, it’s an element of style.
Venting adjustable : Airstream Control - 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.     
Head Phones (MP3-IPOD-Mobile):   No
Goggle system : TRM - The “translatory-rotatory-mechanism” (TRM) seals the visor particularly close to the face. The mechanism allows the visor to rotate from the upper to the lower position. In the lower position, a linear movement (translation) ensures that the visor can be moved towards the eyes. This creates a compact fit of the helmet on the head.
Insulation: Lavalan® is a washable insulation material made of sheep wool, used as a padding in ALPINA ski helmets to provide extra comfort. The sustainably obtained lavalan® wool has both insulating and temperature-regulating properties, is breathable and prevents unpleasant sweat odours from forming thanks to the wool’s natural moisture management and the self-cleaning function of the wool fibres. European wool is exclusively used for production, the short production routes for which allow us to monitor animal welfare. 
Interior removable : Yes
Earpads Removable : Yes EARPADS REMOVABLE
Fit adjustable :  Yes Run System Ergo Snow - 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.
Weight in  grams :  670 grams
Features : Deep neck warmer - Highly comfortable and pleasant climate due to long neck warmer made of soft microfleece
Edge Protect - The lower edge of the helmet is protected by the polycarbonate shell Edge Protect
More details :  Ergomatic - 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.
