Alpina D-Alto L.E. - MTB Helmet

If you're looking for a helmet for narrow heads, you'll find it in the D-Alto. The fit is proven, the comfort high. Due to its features and design, it has a wide range of uses.

Perfect fit for narrow heads: the D-Alto L.E. MTB helmet from Alpina

It is the ideal bike helmet for light off-road terrain. Its matte finish gives it a refined look. The low weight comes from the Inmold manufacturing, where the upper shell is thermally bonded to the Hi-EPS. This results in a strong surface connection, which is responsible for a very stable construction. The lower edge of the helmet is protected by the further polycarbonate shell Edge Protect.

Thanks to the production Made in Germany, the highest manufacturing quality is thereby ensured. The arrangement of ventilation openings guarantees ideal climate management, fly screens keep insects away from the head. With the Run System Ergo+, which is combined with the height-adjustable Custom Fit, the helmet can be perfectly adjusted to the head. Another plus for comfort: the removable, antibacterial padding. With it, you always have a comfortable feeling - no matter how hot the bike ride becomes.

Technologies

AIR FLOW VENTING
Alpina developers spend a lot of time and energy to constantly improve the ventilation of our cycling helmets. Through wind tunnel tested arrangement of vents, our engineers create a "Venturi" effect inside the helmet that cools the head, leading to less sweat and higher performance.

FLY NET
The front vents of the helmet are covered with a mesh fabric. This performs the same function as an insect screen, preventing insect bites on the scalp during hot and humid riding periods and locations.

CERAMIC SHELL
All Inmold-manufactured helmets from Alpina, receive this shatter and scratch resistant polycarbonate shell. The blank is stretched under high heat to the shape of the later helmet and pressed with high pressure on its Hi-EPS body. The material is characterized by several qualities at the same time: It is break- and scratch-resistant, UV-stable as well as antistatic.

CUSTOM FIT
Different head shapes require a flexible fitting system. In combination with the Run System, Custom Fit ensures a non-slip fit. The neckband at the back of the head can be tilted in several stages and grips the head gently without pressure points.

EDGE PROTECT
Edge Protect is a processing method that ensures Inmold helmets have no sharp edges. This reduces the risk of injury in two ways: on the one hand, it protects the hands when handling the helmet, and on the other hand, in the event of an impact, the neck and shoulder area remain protected from scratches when in contact with the lower edge of the helmet.

ERGOMATIC
Proven hundreds of thousands of times and used in all Alpina bicycle helmets: the well-known belt buckle with red push button and multi-stage automatic detent. Ergomatic can be operated with one hand - you can loosen the strap uphill, tighten it downhill - and cannot open itself in the event of a fall.

HI-EPS
The inner shell of every Alpina helmet is made of Hi-EPS ("High Expanded Polystyrene"). It consists of microscopic air chambers, which optimally absorb the forces acting during an impact. Despite optimal protection, HI-EPS ensures extra-thin wall thicknesses and narrow helmet shapes.

INMOLD
In the Inmold production process, the helmet upper shell made of polycarbonate is "baked" together with the EPS granulate of the helmet body under high heat and strong pressure. This creates an extensive and inseparable bond between the upper and lower shells. Advantage: The helmet is very light and at the same time extremely stable.

RUN SYSTEM ERGO+
Like its big brother, the RUN SYSTEM ERGO PRO, Alpina's second most elaborate helmet fitting system features the newly developed, pressure-distributing "headrests" and the new, easier-to-use adjustment wheel. The only difference from the top model is that the wing-shaped supports and the dial are made only of plastic.

SHIELD PROTECT
The removable shield protects against both splashing dirt and direct sunlight.

Y-CLIP
A helmet can only protect as well as it remains in the optimum position on impact. The fixation of the two straps under the ear plays a crucial role here. Alpina's "Y-Clip" system guarantees a millimeter-precise adjustment - in seconds.
