The AIRTIME combines a clean design with the best possible safety. It is particularly lightly built so that it is extremely comfortable to wear. 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. With the aid of a pad set and the Run System Classic, the helmet can be easily adapted to fit any head shape.
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.
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.
RUN SYSTEM CLASSIC: If you only use your bike to run down to the shops there's no need to splash out on a highly sophisticated adjustment system. The Run System Classic fits the bill nicely, with a simple, robust adjustment wheel that is easy to use and keeps the helmet securely where it belongs: on your head.
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.
PAD SET: Alpinas street and park helmets have pads of various thicknesses for size adjustment instead of the Run System. Weight supplement: Manufacturer's Spec
