Alpina - D-Alto L.E
MountainBIKE 06/14 - Grade: Excellent
With its slim fit, the D-ALTO LE is particularly suitable for narrower heads. The light weight is achieved thanks to the Inmold technology which connects the outer shell of the helmet directly with the Hi-EPS inner shell. The edges of the helmet are finished with Edge Protect. A further feature is the high-quality Run System Ergo Pro, which is combined with the Custom Fit System for height adjustment – an additional bonus in respect of comfort and safety. The matt finish further enhances the quality appearance of this helmet.
Note: Please measure the head circumference to get the right helmet size.
HI-EPS: Alpina helmets have inner shells made of Hi-EPS (highly expanded polystyrene). This material consists of many microscopically small air chambers which effectively absorb the forces caused by an impact. Hi-EPS provides optimum protection with the benefit of allowing extra-thin walls.
EDGE PROTECT: Is applied to the lower edges of the helmet by the IN-MOLD method. This is a crucial safety feature in the case of a sideways crash and is effective protection against damage to the HI-EPS in daily use.
CERAMIC: This impact- and scratch-resistant polycarbonate shell is fitted to all Alpina helmets manufactured using the Inmold procedure. The blank workpieces are shaped at high temperature onto the form of the helmet design and the shells are then pressed onto the helmet's Hi-EPS body. The material combines a number of distinct advantages: it is impact- and scratch-resistant, it contains UV stabilisers and is anti-static.
INMOLD TEC: The Inmold production process involves the polycarbonate outer shell of the helmet being heated to a high temperature and "baked" onto the EPS helmet body at high pressure. This produces a permanent bond across the entire surface of the inner and outer shells, producing a helmet with the advantage of being very light yet extremely stable.
SHIELD PROTECT: The removable slide-in visor protects the face both from splashing mud and from solar radiation.
RUN SYSTEM ERGO PRO: The top-of-the-range model of ALPINA's new adjustment systems for the rear of the head features two large "head rests" to the left and right of a newly-designed adjustment wheel. These two wing-shaped pads and the adjustment wheel are made of twin-component mix of plastic and rubber. Since 2014, Run System Ergo Pro has been available in colours to match the helmet.
ERGOMATIC: Tried and tested countless times, this is the buckle used in all Alpina cycle helmets. It features a red push button and multi-step automatic adjustment. It can be used one-handed, so for example you can loosen the strap when riding uphill and tighten it again for the descent, and it cannot come open in the event of a crash.
Y-CLIP: A helmet can only provide proper protection if it stays securely in place in the event of an impact. The fastening that joins the two straps under the ear is critical to this. Alpina's Y-Clip system guarantees a perfect fit down to the last millimetre, all in a matter of seconds.
CUSTOM FIT: As heads vary in shape they need an adjustment system that is flexible. In combination with the Run Systems, Custom Fit ensures a slip-free snug fit. The rear neck support can be adjusted to several angles of incline so that it fits snugly and without undue pressure.
FLY NET: The front ventilation holes have a mesh lining which effectively works as an insect screen to protect the wearer's head from insect bites when riding in hot or humid conditions.
ANTIBACTERIAL INTERIOR: Helmet pads made of a special padding material reduce the formation of bacteria and thus prevent perspiration odors.
