This part is dedicated to the internal elements of the helmets; there are three components to consider:
The padding is the main element to consider if you want a helmet with the perfect size.
When the padding is new it can “press” with decision on your head and your jowls.
That pressure mustn’t be painful or slack; with time, the form of the padding will adapt to your head.
Producers use different types of padding, and I suggest to test several helmets before buying one: surely, you’ll find your perfect helmet.
Materials are anallergic and anti-mould; they are of high quality, and some helmets have the internal padding removable, and other don’t.
Breathing and sweating produce bacteria and moulds, so it’s a good habit to sanitize the helmet sometime.
There are two types of padding:
Removable padding is practical, you can wash it with water and neutral soap.
It is very important to follow the manufacturer’s instruction to dry it (normally out in the sun and in a dry place).
For the unmovable padding there are different types of spray to sanitize and clean the internal.
The duration of the helmet depends on the care that we dedicate to it.
A good maintenance and sanitisation can give a long life (and safety) to your helmet, also more than five years with a daily use.
The retention system is a safety element that composes the helmet, it has an important task: it doesn’t allow to lose the helmet in case of incident or fall.
It is tasked to close the helmet under the throat, connecting the two straps present here; there are two locking systems:
Double rings closure
The micrometric buckle is easy to use, you can quickly open and close it.
It’s important to calibrate well the length of the straps, close them and go.
This system is perfect for short distances or when you have many stops during the travel, like a touristic trip.
The double ring closure, instead, is used in the competitions; its use takes some practice, but then it becomes easy like the micrometric one.
This system is perfect with high speed or for a long transfer.
Producers study many different ventilation systems to make the helmets more comfortable.
Good helmets have many air intakes: on the top of the shell, in the front of chin guard, and there is an air extractor in the rear of helmet.
Ventilation is very important, because it can reduce the fogging in the interior of the visor and control the temperature of the padding.
Sometimes the ventilation is not enough, so the producers use the “Pinlock system”: a little film to apply in the interior of the visor to avoid its fogging.
A good helmet mustn’t expose the nape of the neck, and it has to be well closed in that area.
There is a practice test you can make when you wear a new helmet: pass your arms over the helmet and take the back with your hands, so pull strongly forward; if the helmet slips off you must choose a smaller size.
