How to Choose Your Bicycle Helmet?

There are some factors that you need to think highly of when you choose a bicycle helmet that is absolutely suitable for you.

Some common sense
You may have noticed that most brands use "S-M-L" terminology to describe helmet size. In fact each of these terms frames a few measures in centimeters.
For example the Catlike Mixino is divided into:
SM: Between 52 and 54 centimeters
MD: Between 55 and 57 centimeters
LG: Between 58 and 60 centimeters

How to know the size of our rider helmet?
We simply have to measure the circumference of our skull at the level of the forehead, just above the eyebrows, that is the position in which we must place the helmet.
The same size of helmet can be used for different measures, so when putting on the helmet we must adjust it with the rear wheel. In case of very little adjustment, we must try a larger or smaller size. It is important to keep in mind that the helmet must be fastened but never tightened, as this can cause a headache.

Ventilation of a bicycle helmet
This is one of the key points when it comes to choosing a bicycle helmet. We will use it for hours and during intense physical activity or even strenuous. That is why we must take into account the ventilation, and therefore cooling, that the hull we choose will provide us.
You can juge the ventilation by the following ways.
We can be guided by the number of ventilation holes, this can be a clue as to the amount of air that will "enter" into our head. Now, it is not a matter of quantity but of quality, since the most important thing is to know if the helmet integrates a good driving of the air that circulates in its interior. One trick to determine if a bike helmet has a good ventilation system is to look at it head-on, putting the helmet between a colored wall and us. If by looking at it we can see through the holes the color of the wall means that the air has holes well designed both to enter and exit, thus ensuring a correct wind flow.

Comfort of cycling helmets
Comfort is something very personal and subjective, a helmet that is comfortable for someone to be uncomfortable for another person, both the shape of the head and the fact that we have much or little hair in it.

In any case to know if a helmet is comfortable there are a series of aspects that you must look to orientate you:
1.According to the helmet padding
2.According to the hull fastening
3.According to your accessories
